Data centers, like the Amazon one in Oregon pictured here, are an increasing source of noise pollution.

Turning Down the Heat, and the Noise

With every bicycle that replaces a motorcycle, every garden hose that supplants a power-washer, every rake that displaces a leaf blower, our world will both warm a little more slowly and become a little less noisy..

The most pressing environmental crisis of these times, our heating of the Earth through carbon dioxide and other greenhouse gas pollution, is closely connected to our excessive energy consumption. And with many of the ways we use that energy, we’re also producing another less widely discussed pollutant: industrial noise. Like greenhouse-gas pollution, noise pollution is degrading our world—and it’s not just affecting our bodily and mental health but also the health of ecosystems on which we depend utterly.

Noise pollution, a longstanding menace, is often ignored. It has, however, been making headlines in recent years, thanks to the booming development of massive, boxy, windowless buildings filled with computer servers that process data and handle internet traffic. Those servers generate extreme amounts of heat, the removal of which requires powerful water-chilling equipment. That includes arrays of large fans that, in turn, generate a thunderous wall of noise. Such installations, known by the innocuous term “data centers,” are making growing numbers of people miserable.

Residents of Loudoun County, Virginia, the nation’s data-center epicenter, have filed dozens of complaints about an especially loud facility located in the town of Leesburg. People living as much as three miles from the center compared the noise from its giant cooling fans to the sounds of an airplane engine, a freight train, a huge leaf blower, or a helicopter hovering overhead, day and night.

The data center’s ear-splitting noise was so bad that it drove Mr. Zhang to seek refuge at… O’Hare Airport.

Attorneys representing a group of Williston, North Dakota, homeowners argued last December that noise pollution from the nearby Atlas Power Data Center “is a continual invasion of their homes, their health, and their North Dakota way of life. They are now virtually shut-ins in the slice of North Dakota they once called their own.” In April, Gladys Anderson of Bono, Arkansas, told reporters that a nearby cryptocurrency-mining data center was “like torture, like a form of military-grade torture.” Her neighbor complained, “It’s caused problems for me with my hearing, my blood pressure, with the sweetheart where she gets migraine headaches.”

Chicago-based airline pilot Joshua Zhang—someone who (I’m betting) knows a thing or two about loud noise— told CBS News in 2021 that a new data center in his Printers’ Row neighborhood whined like a gigantic vacuum cleaner that never shuts off. “I try to fly as much as I can to stay away from here,” he said. “I can’t really sleep well… and I have to operate a flight.” In other words, the data center’s ear-splitting noise was so bad that it drove Mr. Zhang to seek refuge at… O’Hare Airport.

Noise Makes Us Sick and We’re Sick of Noise

The recent, rapid proliferation of data centers has been due, at least in part, to the similarly rapid growth of two types of enterprises: cryptocurrency and artificial intelligence (AI). Those voracious wasters of electricity were unasked-for inventions that filled largely nonexistent human needs. And they’re amplifying the very real problem of noise pollution.

Crypto and AI illustrate a larger issue. An all-out effort to curb climate change will require deep reductions in the use of fossil fuels, which will, in turn, require more frugal use of all forms of energy. And if that happens (as it should), it will have profound repercussions throughout society. As one of the more welcome consequences, our now-cacophonous world is likely to become easier on the ears.

With every AI project abandoned, every bitcoin not mined, every pickup truck not sold, every jet fighter not flown, people somewhere will get relief. With every bicycle that replaces a motorcycle, every garden hose that supplants a power-washer, every rake that displaces a leaf blower, our world will both warm a little more slowly and become a little less noisy.

The severe impact of noise pollution on both mental and physical health is well documented. Hearing impairment is the most obvious malady it causes. The World Health Organization (WHO) finds that noise pollution severely disrupts our quality of life in other ways, too, raising the risk of heart disease, childhood cognitive impairment, sleep disturbance, and general annoyance. WHO notes that while

...annoyance is not normally classified as a health effect, it certainly affects well-being and therefore is considered to fall within the WHO definition of health as being “a state of complete physical, mental, and social well-being.” More importantly, however, it is the effect of noise that most lay people are aware of and concerned about.

And annoyance can be a gateway to much worse, to “feelings of disturbance, aggravation, dissatisfaction, concern, bother, displeasure, harassment, irritation, nuisance, vexation, exasperation, discomfort, uneasiness, distress, hate, etc.” You might think I got that quote from a thesaurus, but, no, it’s from a study published in the journal Noise and Health . Any person living near a data center or other source of loud, continuous noise can, I expect, attest to having experienced most (or all) of those feelings. And it’s well known that such stresses can lead to physiological health problems.

When it comes to making people miserable, keep in mind that not all noises are created equal. The roar from data centers, vehicle traffic, commercial lawn-care operations, and other notorious disturbers of the peace is rich in low-pitched audible frequencies that travel much further than others and can even pass through walls. Such low tones also irritate us more, even when they aren’t all that loud. Consequently, and unfortunately, people complaining about their exposure to noise from data centers or other sources of low-frequency noise are all too often dismissed as hypochondriacs. In a recent, comprehensive article on noise pollution in The   Atlantic magazine, Bianca Bosker told a gripping tale of how people in Chandler, Arizona, suffered for years as their complaints about data center noise were casually dismissed by local authorities.

The Cruelty Is the Point

For those of us not living near a data center, road traffic may be the most pervasive, day-to-day source of unhealthful low-frequency noise. In the European Union, for example, 113 million people, or 20% percent of the population, live with noise pollution from road traffic that’s loud enough to raise risks of heart disease and heart failure. The risk of developing diabetes, obesity, anxiety, depression, and of course, sleep disturbance also increases as traffic noise gets louder.

Of course, we produce traffic noise collectively and most, but not all, of us hate it. In an April essay entitled “What is Noise?,” New Yorker music critic Alex Ross observed that “if you elect to hear something, it is not noise, even if most people might deem it unspeakably horrible. If you are forced to hear something, it is noise, even if most people might deem it ineffably gorgeous.” Extra-loud vehicles, particularly en masse, richly illustrate Ross’s observation.

In recent decades, American pickup trucks and SUVs have grown steadily larger and heavier, with towering front ends and armoring that create a road-ruling mystique. Increasingly, to further satisfy consumer demand for big, intimidating vehicles, automakers equip many of them with high-decibel engines, turbochargers, and thunderous exhaust systems. Drivers all too regularly dial the volume up several more notches with muffler modifications that are often illegal. The automakers’ economic motivation for offering big, loud vehicles is clear ($), but why exactly do their customers want them? The deafening din emanating from those trucks has distinct political undertones , but there may also be something deeper going on.

A 2023 study published in the journal Current Issues in Personality Psychology sheds some light on this. The researcher interviewed 529 people, split almost equally between the sexes, about their attitudes toward noisy vehicles. Then, using questionnaires, she evaluated the subjects for four “dark” personality traits: Machiavellianism, narcissism, psychopathy, and sadism. It turned out (surprise!) that men liked loud vehicles significantly more than women did. Across both sexes, those who expressed greater fondness for such vehicles also tended to score higher for two dark personality traits: psychopathy and sadism. The researcher drily observed that the results made perfect sense:

Psychopathy reflects an up-close cruelty, whereas sadism includes viewing the harm to others from a distance… Modifying a muffler to make a car louder is disturbing to pedestrians, other drivers, and animals at a distance, meeting the sadism component, as well as startling when [the victim is] up close at intersections, meeting the psychopathy component.

The author of that study is not a medical professional (nor am I); still, it’s not exactly illogical to consider guys who alter their trucks to produce brain-rattling noise psychopaths. I’m not a lawyer either, but it still seems to me that labeling such practices a form of reckless indifference to human well-being is anything but unreasonable.

Quietness Should Be a Right, Not a Privilege

For decades, the environmental justice movement has been fighting a longstanding American tradition of locating dirty, dangerous industries and activities in low-income, racialized communities. This is a problem that arises with every environmental issue, and noise is no exception. Alex Ross recognized that in his “What Is Noise?” essay when he observed, “Silence is a luxury of the rich… For the rest of society, noise is an index of struggle.”

In neighborhoods with lower socioeconomic status and/or large Indigenous, Asian, Black, or Latino populations, residents endure greater exposure to noise pollution, especially in areas where informal racial segregation is more severe. Not surprisingly, a separate study found that the same demographic groups experience highly disproportionate levels of annoyance from noise caused by road traffic or aircraft.

Consider it a certain irony then that, despite being exposed to less noise pollution, white Americans are subject to significantly higher rates of hearing loss than Black Americans—and it’s unclear why. Andrew Van Dam of The Washington Post complicated matters further when he noted that there’s also a political disparity : The higher the share of Republicans in a state or county, the greater the rate of hearing loss. He couldn’t fully explain this as a result of populations in redder states being generally whiter and older. There had to be some other factor. When Van Dam looked further, he found one that made a big difference in the prevalence of hearing loss: Politically redder areas have higher rates of recreational firearm ownership than bluer areas, with lots more hunting and gun-range target practice—another kind of noise pollution entirely.

No Peace, No Quiet

The U.S. military also has lots of guns, as well as an enormous climate footprint . A dramatic downsizing of our war-making capacity (and the staggering Pentagon budgets that go with it)—badly needed for both humanitarian and ecological reasons—would have the salutary side-effect of shrinking one of our major sources of noise pollution and hearing loss.

It should come as no surprise that researchers in a wide range of countries have found that hearing loss is more common among military personnel than in the general population. Among American service members, almost 15% suffer hearing impairment. Hearing loss is one of the most common health problems of veterans, especially those who served in special forces units (where it’s twice as prevalent as elsewhere in the armed forces). The exposure of those in such units to large-caliber weapon fire, urban combat training, and the like clearly has a lot to do with that.

In military operations, jet aircraft are the most intense source of both greenhouse-gas emissions and noise pollution. Jets account for almost 80% of the military’s fuel consumption. Their noise output is not as precisely quantified, but recent research in a study on civilian impacts around Naval Air Station Whidbey Island in Washington State found that, in the county where the base is located, two-thirds of the resident population were exposed to noise levels that could have negative health effects. One-fifth suffered high levels of annoyance and 9% were “highly sleep disturbed.” Worse yet, according to that study, “the Swinomish Indian Tribal Community of the Swinomish Reservation [located northeast of the airfield] was extremely vulnerable to health risks, with nearly 85% of residents being exposed.”

In Salina, Kansas, where Priti Gulati Cox and I live, we have less frequent but highly immersive experiences with military noise pollution every time the curiously named “ Jaded Thunder joint exercise” comes to town. In part of that “exercise,” pilots from the Air Force, Army, Marines, and Navy take off from a nearby airfield in fighter jets and fly low over our city of 50,000. The noise hits you suddenly, like a roundhouse punch. It’s like nothing I’ve heard or felt elsewhere. My own reaction to such overwhelming noise levels is similar to those found in survey responses from several residents of Madison, Wisconsin, who hear fighter jet noise much more routinely than we Salinans do. As one of them put it: “Everything I’m doing comes to a halt… my entire body tenses up and my heart starts racing… utterly jarring… impossible to make out dialogue… impossible to just continue any activity… reminds me of every innocent soul killed in a bombing by my home country.” Finally, there was simply this: “Annoyed.”

Cooler Means Quieter

America was getting louder before the rise of data centers, but now it’s getting louder faster. Unfortunately, the research on that is sparse, but it’s still a reasonable conclusion to draw. In her article, Bianca Bosker pointed out another intriguing indicator of our rising noise problem. Fire-engine sirens today are designed to be more than twice as loud as those of the 1970s, just so they’ll be audible above the rising din of our cities and suburbs. And keep in mind that they’re eight times as loud as the sirens of 1912.

Climate mitigation is also noise mitigation. To avoid baking the Earth, governments must quickly phase out the use of oil, gas, and coal. With a slimmed-down energy supply, economies will need to direct fuels and electricity toward uses that meet more essential needs. Crypto and AI are not among such uses, nor can we afford to keep streets and highways crammed with gas- and diesel-guzzling private vehicles. For those and many other reasons, count on one thing: Strong efforts to reduce greenhouse gas emissions will also have striking beneficial side effects, including more peace and quiet. And that should be music to our ears.

Essay Writing on Noise Pollution in 250 Words

Noise pollution, often referred to as unwanted or harmful sound, has become a pervasive issue in modern society. According to the World Health Organization (WHO), environmental noise affects millions of people worldwide, with urban populations particularly vulnerable. This essay examines the causes, consequences, and potential remedies for noise pollution.

Causes and Sources

The primary sources of noise pollution include transportation, industrial activities, construction, and recreational events. In urban areas, traffic noise is a major contributor, with studies indicating that it exceeds recommended levels in many cities. Industrial machinery, such as factories and power plants, also emit high levels of noise, impacting surrounding communities. Additionally, construction projects produce significant noise during excavation, demolition, and building phases. Moreover, social gatherings, concerts, and festivals contribute to noise pollution, especially in residential areas.

Health Impacts

Exposure to excessive noise has detrimental effects on human health. Chronic noise exposure can lead to hearing loss, sleep disturbances, stress, and hypertension. The WHO estimates that environmental noise causes thousands of premature deaths annually due to cardiovascular diseases. Children exposed to noise pollution may experience learning difficulties and impaired cognitive development. Furthermore, noise-induced sleep disturbances can result in fatigue and decreased productivity, affecting overall well-being.

Environmental Consequences

Noise pollution not only affects humans but also disrupts ecosystems and wildlife. Studies have shown that noise pollution alters animal behavior, communication, and reproductive patterns. Marine mammals, such as whales and dolphins, are particularly vulnerable to underwater noise pollution, which interferes with their navigation and feeding activities. In terrestrial ecosystems, excessive noise can drive wildlife away from their natural habitats, leading to habitat fragmentation and biodiversity loss.

Mitigation Strategies

To address noise pollution, a multi-faceted approach is necessary, including stricter regulations, technological innovations, and community engagement. Governments and urban planners can implement noise abatement measures, such as sound barriers, traffic management, and land use planning. Additionally, advancements in noise-reducing technologies for vehicles, machinery, and construction equipment can help mitigate noise emissions.

Writing an Essay on Noise Pollution in 500 Words

Noise pollution, an increasingly prevalent environmental problem, poses significant challenges to human health, well-being, and the ecosystem. According to a report by the United Nations Environment Programme (UNEP), approximately 1.6 billion people worldwide are exposed to unhealthy levels of noise pollution. This essay aims to delve into the complex causes, multifaceted impacts, and potential solutions to mitigate noise pollution.

Noise pollution originates from various anthropogenic activities, including transportation, industrial operations, construction, and recreational events. In urban areas, traffic noise is a major contributor, with studies indicating that it surpasses acceptable levels in many cities globally. Industrial facilities, such as factories and power plants, emit substantial noise during their operations, affecting nearby communities. Construction activities, including drilling, hammering, and heavy machinery operation, also contribute significantly to noise pollution. Moreover, social gatherings, concerts, and outdoor events produce excessive noise, particularly in residential areas.

Exposure to high levels of noise pollution can have profound effects on human health. Chronic noise exposure is associated with various adverse health outcomes, including hearing loss, cardiovascular diseases, sleep disturbances, and mental health disorders. The World Health Organization (WHO) estimates that environmental noise contributes to thousands of premature deaths annually due to heart disease and stroke. Furthermore, children exposed to noise pollution may experience learning difficulties and impaired cognitive development. Noise-induced sleep disturbances can lead to fatigue, irritability, and decreased productivity, impacting overall well-being.

Noise pollution not only affects human health but also disrupts ecosystems and wildlife. Studies have shown that noise pollution alters animal behavior, communication, and reproductive patterns. Marine mammals, such as whales and dolphins, are particularly vulnerable to underwater noise pollution, which interferes with their navigation, communication, and foraging activities. Terrestrial wildlife may experience habitat fragmentation and displacement due to excessive noise levels, leading to biodiversity loss and ecological imbalances.

Economic Impacts

The economic costs of noise pollution are significant, encompassing healthcare expenditures, property devaluation, and productivity losses. According to a study by the European Commission, the economic burden of noise pollution in the European Union amounts to billions of euros annually. Healthcare costs associated with noise-induced health problems, such as hearing loss and cardiovascular diseases, place a substantial burden on public health systems. Additionally, property values in noisy areas tend to depreciate, affecting homeowners and local economies. Moreover, noise-induced productivity losses in workplaces result from decreased concentration, communication difficulties, and stress-related absenteeism.

Regulatory Framework

To address noise pollution, governments and regulatory authorities have implemented various policies and regulations. These include noise standards, zoning ordinances, and land use planning measures aimed at controlling noise emissions and protecting sensitive receptors. For instance, the Environmental Protection Agency (EPA) in the United States sets noise standards for vehicles, machinery, and industrial facilities to limit noise pollution. Similarly, urban planning strategies such as green buffers and sound barriers are employed to mitigate noise impacts in urban areas.

Technological Innovations

Advancements in noise-reducing technologies offer promising solutions to mitigate noise pollution. Innovations such as acoustic insulation, sound-absorbing materials, and noise-canceling devices help reduce noise emissions from transportation, industrial operations, and construction activities. Additionally, electric vehicles and hybrid engines produce lower noise levels compared to traditional combustion engines, contributing to noise reduction in urban environments.

Public Awareness and Education

Raising public awareness and fostering community engagement are essential aspects of noise pollution mitigation efforts. Education campaigns, noise awareness programs, and community outreach initiatives can empower individuals to take proactive measures to reduce noise emissions and protect their health and well-being. Moreover, promoting responsible behavior, such as minimizing noise during leisure activities and adhering to noise regulations, can contribute to creating quieter and more livable communities.

In conclusion, noise pollution is a complex and pervasive environmental problem with far-reaching impacts on human health, the environment, and the economy. Addressing this issue requires a holistic approach, integrating regulatory measures, technological innovations, and public education efforts. By implementing effective strategies to mitigate noise pollution and fostering a culture of noise awareness and responsibility, we can create healthier, more sustainable living environments for present and future generations.

Essay on Noise Pollution for Students and Children

500+ words essay on noise pollution.

Essay on Noise Pollution: Noise pollution is a form of pollution which has become very deadly nowadays. This pollution is increasing only and creates an unsafe environment . Noise pollution is when the level of noise increases more than the normal level. When the amount of noise exceeds, it becomes dangerous for living beings. Moreover, these unpleasant sounds cause several disturbances and create an imbalance in the environment.

In other words, high volume noises are abnormal. As the world is advancing at a rapid rate, so is noise pollution. Technology has made things easier for people by creating appliances and devices for almost everything. You want to mix or grind something? It can be done with a mixer and blender. You are feeling hot? Simply turn on the AC or cooler. Do you want entertainment at home? You can watch television or play music. However, people don’t realize this comfort comes with harmful effects too. All the mentioned appliances contribute to noise pollution. They disturb the natural rhythm of life and fall in the category of a pollutant .

What causes Noise Pollution?

As the world is turning to technology for their comfort, it is, at the same time, harming us. The industries no matter how big or small contribution to noise pollution . The equipment they use like compressors, exhaust fans, generators and more produce a lot of noise.

Similarly, the ever-increasing use of automobiles is a major cause of this pollution. Not only automobiles but other transport vehicles like airplanes, buses, bikes, trucks and more also are a part of it. People honk unnecessarily in the traffic and listen to loud music on the way which creates high levels of noise .

Furthermore, social events like marriages, parties, and religious functions in places like clubs, pubs, temples, halls and more create a lot of nuisance in the residential areas. In addition, the construction activities like mining, the building of flyovers, bridges and more also produce great noise.

The Damaging Impact of Noise Pollution

Similarly, it reduces the ear sensitivity to the sounds that the human body requires to regulate our rhythm of the body. Moreover, it also affects our psychological health. It may not be evident instantly, but in the long run, it changes our behavior.

When your sleep gets disturbed or you constantly have headaches because of too much noise, you tend to experience fatigue and even migraines.

Not only humans but noise pollution also impacts wildlife too. For instance, pets become aggressive or afraid when they hear a loud noise. It is one of the main reasons why crackers are not encouraged when pets are around. In short, we must make people aware of the impact of noise pollution. Likewise, we must encourage them to adopt ways that do not contribute to noise pollution. If everyone starts doing the same on an individual level, we will surely be able to reduce noise pollution to a great extent.

ENCYCLOPEDIC ENTRY

Noise pollution.

Noise pollution can cause health problems for people and wildlife, both on land and in the sea. From traffic noise to rock concerts, loud or inescapable sounds can cause hearing loss, stress, and high blood pressure. Noise from ships and human activities in the ocean is harmful to whales and dolphins that depend on echolocation to survive.

Noise pollution is an invisible danger. It cannot be seen, but it is present nonetheless, both on land and under the sea. Noise pollution is considered to be any unwanted or disturbing sound that affects the health and well-being of humans and other organisms.

Sound is measured in decibels . There are many sounds in the environment, from rustling leaves (20 to 30 decibels ) to a thunderclap (120 decibels ) to the wail of a siren (120 to 140 decibels ). Sounds that reach 85 decibels or higher can harm a person’s ears. Sound sources that exceed this threshold include familiar things, such as power lawn mowers (90 decibels ), subway trains (90 to 115 decibels ), and loud rock concerts (110 to 120 decibels ).

Noise pollution impacts millions of people on a daily basis. The most common health problem it causes is Noise Induced Hearing Loss (NIHL). Exposure to loud noise can also cause high blood pressure, heart disease, sleep disturbances, and stress. These health problems can affect all age groups, especially children. Many children who live near noisy airports or streets have been found to suffer from stress and other problems, such as impairments in memory, attention level, and reading skill.

Noise pollution also impacts the health and well-being of wildlife. Studies have shown that loud noises can cause caterpillars' dorsal vessels (the insect equivalent of a heart) to beat faster, and cause bluebirds to have fewer chicks. Animals use sound for a variety of reasons, including to navigate, find food, attract mates, and avoid predators. Noise pollution makes it difficult for them to accomplish these tasks, which affects their ability survive.

Increasing noise is not only affecting animals on land, it is also a growing problem for those that live in the ocean. Ships, oil drills, sonar devices, and seismic tests have made the once tranquil marine environment loud and chaotic. Whales and dolphins are particularly impacted by noise pollution . These marine mammals rely on echolocation to communicate, navigate, feed, and find mates, and excess noise interferes with their ability to effectively echolocate.

Some of the loudest underwater noise comes from naval sonar devices. Sonar , like echolocation , works by sending pulses of sound down into the depths of the ocean to bounce off an object and return an echo to the ship, which indicates a location for object. Sonar sounds can be as loud as 235 decibels and travel hundreds of miles under water, interfering with whales’ ability to use echolocation . Research has shown that sonar can cause mass strandings of whales on beaches and alter the feeding behavior of endangered blue whales ( Balaenoptera musculus ). Environmental groups are urging the U.S. Navy to stop or reduce using sonar for military training.

Seismic surveys also produce loud blasts of sound within the ocean. Ships looking for deep-sea oil or gas deposits tow devices called air guns and shoot pulses of sound down to the ocean floor. The sound blasts can damage the ears of marine animals and cause serious injury. Scientists believe this noise may also be contributing to the altered behavior of whales.

Among those researching the effects of noise pollution is Michel Andre, a bioacoustics researcher in Spain who is recording ocean sounds using instruments called hydrophones . His project, LIDO (Listening to the Deep Ocean Environment), collects data at 22 different locations. Back in the lab, computers identify the sounds of human activities as well as 26 species of whales and dolphins. The analysis aims to determine the effects that underwater noise is having on these animals. Andre hopes his project will find ways to protect marine animals from the dangers of ocean noise.

Have you ever been somewhere truly free from the sounds of humankind? We become immune to the sounds of distant traffic and especially the subtle hum of planes above, but there are few places that don't have some form of noise pollution.

Noise pollution is noise that has surpassed ambient noise levels and has a harmful impact on humans and animals. This type of pollution is generated by humans and is a form of environmental degradation. It can serve as a source of stress on fauna, can have negative effects on animal welfare, and can even cause behavioral changes in birds, according to a study on the impacts of noise pollution on birds.  

Noise pollution can be problematic when frequencies that are produced disrupt information transmission in animals, specifically animals that use similar frequencies to communicate. These disturbances can also lead to higher anti-predator behaviors in situations that don’t require it, as well as change species vocalization, increase stress and stress-related diseases, and have the potential to decrease populations.

Noise Pollution Facts

• The third most common chronic physical condition in the United States is hearing loss. (CDC)
• Over 100 million people in the European Union are exposed to traffic noise above 55 decibels (dB), according to a study looking at noise pollution and its health effects.
• Noise over 70 dB over a long period of time can damage your hearing, and noise above 120 dB can cause immediate damage to your ears. The average sound of a firework is 140 dB, and the average sound of traffic (from inside the car) is 80 to 85 dB. ( CDC )
• Noise pollution threatens the survival of over 100 species.

Noise pollution can also be defined as an unwanted sound. The noise that is studied usually refers to occupational noise instead of social noise or environmental noise like construction.

In the E.U., around 56 million who live in areas with a population size of more than 250,000 people are exposed to more than average traffic noise. In the United States, noise has been shown to be increasing in California due to street traffic and increased at a rate of 6.7 dBA (A-weighted decibels). 

Noise pollution's impact on the environment can be classified as:

• Chronic Contamination / Continuous Noise : Constant exposure to noise; this type of pollution can lead to hearing impairment.
• Temporary Contamination with Physiological Damage : Exposure to a limited source of noise; an example is exposure to explosives.
• Temporary Pollution Without Damage : Continuous noise for a limited period of time, like street noise—this can lead to temporary hearing impairments.

Meanwhile, low-frequency noise is described as the background noise that comes from urban environments like air conditioning systems or vehicles. Traffic accounts for 80% of the environmental impact of noise. In animals, traffic noise can reduce foraging efficiency, and in birds can affect their reproductive system.

Examples of Noise Pollution

Barcelona , Spain

Barcelona is among the top cities exposed to noise pollution. Almost 48% of city blocks had an average noise level over 65dB, and only 5% of city blocks had noise levels under 55dB, according to research on environmental noise inequities in the city. The area with the highest noise level was the Eixample district; this district has high flows of street traffic and is also where the very popular La Sagrada Familia is located. This district, as well as the Sarria-Sant Gervasi district, experience levels over 70dB. In Barcelona, 94% of the population lives in city blocks that experience high-noise levels. In Madrid, 80% of all urban noise comes from road traffic, according to an impact assessment of traffic noise in Madrid . In general, the E.U. has shown that 65% of Europeans live in major urban areas that are exposed to high noise levels.

New York City, United States

Noise has been consistently reported as the number-one quality-of-life issue affecting residents in New York City. Sound pressure levels were reported at 70 to 85 dB in midtown Manhattan, which is above average and is at a level that poses health hazards, according to an assessment of noise pollution in NYC . More than two million people in New York City reported that they were disturbed from sleep by noise once a week; 78% of those people reported being disturbed three or more nights each week, according to a paper on the effects of ambient noise on sleep . Traffic noise caused 53% of sleep disturbances. Measured locations in New York City with noise levels greater than 70dB increased risk of hearing loss. These noise levels were especially high in areas with a lot of traffic, during the morning and evening commuting periods, and all around Manhattan, as reported in an assessment of street-level noise in New York City. The assessment also found that the highest noise measurement occurred when sirens, heavy pedestrian traffic, or construction was present. Street-level noises contribute to 4% of total noise exposed to the NYC public.

Noise Pollution and the Clean Air Act

The Clean Air Act Amendment added Title IV to the document, which relates to noise pollution. This amendment established the EPA Office of Noise Abatement and Control to study the effect of noise on public health and the effect on wildlife, the psychological and physiological effects it may have on people, and the effect of sporadic extreme noise. The sources of noise that are regulated by the EPA include construction equipment, trucks, transport equipment, low-noise emission products, and rail and motor carriers. It also regulates the labeling of hearing protection devices.  During the time this amendment was written, the EPA identified the average exposure to environmental noise to be 70 dB over 24 hours and average levels of 55 dB outdoors. However, the Office of Noise Abatement and Control was closed as the administration thought it was best if issues regarding noise were handled at the local and State level, according to the EPA .

The Noise Control Act of 1972 and the Quiet Communities Act essentially replaced the office and have yet to be rescinded, however the EPA’s website states they are “essentially unfunded.” Since the Clean Air Act and the previously mentioned amendment are no longer enforced, people can look at their state’s regulations. For example, Colorado limits the decibels produced by noise in residential, commercial, light industrial, and industrial zones between a set time. Their statute also considers periodic, intrusive, or shrill noises as a nuisance. The California Noise Control Act reiterates the harm excessive noise can have on physiological and psychological health, and also states that people in California are entitled to having a “peaceful and quiet” environment without noise that could be hazardous to their health.

The greatest effect of noise pollution on the environment is on animals. Noise pollution can affect an animal's ability to detect acoustic signals, affect courtship behaviors, cause birds to produce fewer eggs, and cause fewer offspring to reach reproductive age. On detecting acoustic signals, noise can also be produced in the same frequencies in which animals vocalize and can interrupt the transmission of information.

Noise affects many species of animals, from amphibians, arthropods, birds, and fish to mammals, mollusks, and reptiles.

According to the World Health Organization, noise is one of the most hazardous forms of pollution and has become omnipresent in aquatic and terrestrial ecosystems.

How Noise Affects Animals

• It hampers communication . Most animals rely on vocalizations and other acoustic signals to communicate with each other. Interference makes it challenging for animals to find mates, warn of danger, establish territories, and coordinate group activities.
• It disrupts reproduction : Noise pollution is distracting and can disrupt breeding behaviors and lead to diminished reproductive success. For instance, loud noises near nesting sites can cause birds to abandon their nests.
• It compromises dwindling habitat : Noise can reduce the quality of usable habitat, something that is already in critical decline.
• It alters foraging patterns : Noise pollution can change the foraging patterns of animals. For example, ship noise can cause marine mammals to avoid certain feeding grounds.
• It leads to stress and health issues : Just like in human animals, prolonged exposure to loud and constant noise can lead to chronic stress in non-human animals, which can have many adverse effects.
• It drowns out environmental cues : Noise pollution can make it hard to hear important environmental cues that animals have always relied on to navigate and detect predators or prey.
• It disorients and can cause strandings : Particularly in aquatic environments, noise—like that from ships or oil extraction activities—can disorient marine animals and lead to beach strandings or collisions with boats.

These disturbances can have long-term consequences. For example, some species may perform anti-predator behavior due to the confusion noise may create, as is the case with the impact of noise pollution on the saffron finch.

In this case, the noise created by traffic changed the behavior of saffron finches and made them less aggressive. In an environment with heavy noise, the male bird would display less aggressive behaviors when confronted by an intruding bird. This may be because they pay less attention to the intruder if unwanted noise masks the information that dictates the attributes of the intruder. The study predicts that if noise pollution were to continue, this species would continue to exhibit anti-predator behavior, as well as eat and reproduce less. This type of behavioral change was also found in the chipping sparrow.

Trees can be used against noise pollution, according to an investigation on the effects of leaves, branches, and canopies on noise pollution. By decreasing the area in which noise is made and increasing tree presence with tree belts of at least 12 meters, trees could serve as a noise barrier in urban areas. Another study found that tree belts with a width of 30 meters could be planted on the roadside and have more than 6dB reduction of noise than a grassland would. The conclusion was that more trees, branches, and leaves could reduce noise pollution.

Regulations have also been placed in the U.S. statewide and local governments to reduce noise pollution. New York, for example, has a regulation that looks at occupational noise exposure; this ranges from monitoring noise to providing personal protective equipment. Many states and local governments in the U.S. have their own regulations regarding noise pollution; however, many focus on the human impacts that noise pollution has and not the environmental impacts.

How Can You Help?

• Advocate for planting trees and vegetation, or plant trees yourself. Trees can serve as a great noise barrier and have many other benefits as well.
• Turn down the volume on your television, music, and car stereo—especially in urban and residential areas where people can overhear your entertainment.
• If you own a car or motorcycle, ensure it's well-maintained to minimize engine noise.
• Check your road rage and limit unnecessary honking.
• Limit the use of loud machinery or equipment.
• Opt for electric gardening equipment—gas-powered lawnmowers and leafblowers are a bane for your neighbors.
• Opt for an electric car, which reduces engine noise from traffic.
• Use soundproofing in your home or workspace to decrease the noise you hear and the noise you emit.
• Advocate for quiet zones in public places, like parks, libraries, or public transportation.
• Research and support local and national noise-reduction policies and regulations.
• Become active in local community initiatives to reduce noise pollution, such as organizing noise awareness campaigns or supporting noise-reduction projects.

noise pollution , unwanted or excessive sound that can have deleterious effects on human health, wildlife, and environmental quality. Noise pollution is commonly generated inside many industrial facilities and some other workplaces, but it also comes from highway, railway, and airplane traffic and from outdoor construction activities.

Sound waves are vibrations of air molecules carried from a noise source to the ear. Sound is typically described in terms of the loudness ( amplitude ) and the pitch ( frequency ) of the wave . Loudness (also called sound pressure level, or SPL) is measured in logarithmic units called decibels (dB). The normal human ear can detect sounds that range between 0 dB (hearing threshold) and about 140 dB, with sounds between 120dB and 140 dB causing pain (pain threshold). The ambient SPL in a library is about 35 dB, while that inside a moving bus or subway train is roughly 85 dB; building construction activities can generate SPLs as high as 105 dB at the source. SPLs decrease with distance from the source.

The rate at which sound energy is transmitted, called sound intensity , is proportional to the square of the SPL. Because of the logarithmic nature of the decibel scale, an increase of 10 dB represents a 10-fold increase in sound intensity, an increase of 20 dB represents a 100-fold increase in intensity, a 30-dB increase represents a 1,000-fold increase in intensity, and so on. When sound intensity is doubled, on the other hand, the SPL increases by only 3 dB. For example, if a construction drill causes a noise level of about 90 dB, then two identical drills operating side by side will cause a noise level of 93 dB. On the other hand, when two sounds that differ by more than 15 dB in SPL are combined, the weaker sound is masked (or drowned out) by the louder sound. For example, if an 80-dB drill is operating next to a 95-dB dozer at a construction site, the combined SPL of those two sources will be measured as 95 dB; the less intense sound from the compressor will not be noticeable.

Frequency of a sound wave is expressed in cycles per second (cps), but hertz (Hz) is more commonly used (1 cps = 1 Hz). The human eardrum is a very sensitive organ with a large dynamic range, being able to detect sounds at frequencies as low as 20 Hz (a very low pitch) up to about 20,000 Hz (a very high pitch). The pitch of a human voice in normal conversation occurs at frequencies between 250 Hz and 2,000 Hz.

Precise measurement and scientific description of sound levels differ from most subjective human perceptions and opinions about sound. Subjective human responses to noise depend on both pitch and loudness. People with normal hearing generally perceive high-frequency sounds to be louder than low-frequency sounds of the same amplitude. For this reason, electronic sound-level meters used to measure noise levels take into account the variations of perceived loudness with pitch. Frequency filters in the meters serve to match meter readings with the sensitivity of the human ear and the relative loudness of various sounds. The so-called A-weighted filter, for example, is commonly used for measuring ambient community noise. SPL measurements made with this filter are expressed as A-weighted decibels, or dBA. Most people perceive and describe a 6- to 10-dBA increase in an SPL reading to be a doubling of “loudness.” Another system, the C-weighted (dBC) scale, is sometimes used for impact noise levels, such as gunfire, and tends to be more accurate than dBA for the perceived loudness of sounds with low frequency components.

Noise levels generally vary with time, so noise measurement data are reported as time-averaged values to express overall noise levels. There are several ways to do this. For example, the results of a set of repeated sound-level measurements may be reported as L 90 = 75 dBA, meaning that the levels were equal to or higher than 75 dBA for 90 percent of the time. Another unit, called equivalent sound levels (L eq ), can be used to express an average SPL over any period of interest, such as an eight-hour workday. (L eq is a logarithmic average rather than an arithmetic average, so loud events prevail in the overall result.) A unit called day-night sound level (DNL or L dn ) accounts for the fact that people are more sensitive to noise during the night, so a 10-dBA penalty is added to SPL values that are measured between 10 pm and 7 am . DNL measurements are very useful for describing overall community exposure to aircraft noise, for example.

Noise is more than a mere nuisance. At certain levels and durations of exposure, it can cause physical damage to the eardrum and the sensitive hair cells of the inner ear and result in temporary or permanent hearing loss , known as noise-induced hearing loss. Hearing loss does not usually occur at SPLs below 80 dBA (eight-hour exposure levels are best kept below 85 dBA), but most people repeatedly exposed to more than 105 dBA will have permanent hearing loss to some extent. In addition to causing hearing loss, excessive noise exposure can raise blood pressure and pulse rates, cause irritability, anxiety , and mental fatigue, and interfere with sleep , recreation, and personal communication. Children living in areas with high levels of noise pollution may suffer from stress and other problems, such as impairments in memory and attention span. Noise pollution control is therefore important in the workplace and in the community.

Noise pollution also impacts wildlife. A wide range of animals, including insects , frogs , birds , and bats , rely on sound for a variety of reasons. Noise pollution can interfere with an animal’s ability to attract a mate, communicate, navigate, find food, or avoid predators and thus can even be an existential threat to vulnerable organisms. The problem of noise pollution is especially serious for marine animals, particularly those that rely on echolocation , such as certain whales and dolphins , and much of the world’s oceans are polluted with chaotic sounds from ships, seismic tests, and oil drills. Some of the loudest and most detrimental sounds in the sea are from naval sonar devices, whose noise can travel hundreds of miles through the water and is associated with mass strandings of whales and dolphins.

Introduction

Noise as one of the greatest hazards of this world, noise pollution in law, application of methods in real life, the truax model, works cited.

Little sound and noise we all require to live in the society but when this noise and sound becomes unbearable and very loud, it turns to noise and sound pollution. The word noise originated from the Latin term “nausea”, meaning uncalled for. “Noise is defined as unwanted sound; sound, which pleases the listeners is music and that which causes pain and annoyance is noise”. (Jaiswal & Jaiswal, 327) However, “Sound is a kind of energy that allows the particles in the air, a liquid or a solid to vibrate”. (Occupational Health Clinic for Ontario Workers, Online)

For all living inside the arena of the technological world and amidst the cities and towns, noise has become a part of life except for all those fortunate who are still living in the laps of nature away from any busy roads, screaming industries and factories, sounds of loud music, etc. Twenty hours a day we have to bear these sounds and we have increased our toleration level and endurance towards them, but amidst this too when sound becomes too loud, it becomes unbearable causing health hazards.

In the early years of the 1890s, journals of America and London raised the people’s consciousness towards noise as one of the greatest hazards of this world, but people had already got aware to the noise problem during the time when “Epic of Gilgamesh” was written and read in the 3 rd millennium BC. In the Sumerian account of the flood, it was written, “in those days the world teemed, the people multiplied, the world bellowed like a wild bull, and the great God was aroused by the clamour. Enlil heard the clamour and he said to the Gods in council, “the uproar of mankind is intolerable and sleep is no longer possible by reason of the babel. So Gods in the heart were moved to let loose the diluge”.

Now the noise problem is no doubt has become a matter of grave concern for politicians, environmentalists, and basis for legal actions and a topic for health-conscious people. But rarely it is considered as a human problem that is a part of the system acoustic communications. Sound creates a relationship between the individual and environment whereas noise becomes a mediator but creates a negative impact on such mediations and makes the contact between the individual and communicator impossible; it also creates hindrance on the part of effective communications. But what constitutes noise and when sound becomes noise, the concept of this since Helmholtz has been, “the physical acoustic definition of noise has been that it is a non-periodic vibration, by comparison to musical sound, which has a periodicity and therefore a pitch”. (Traux, 95).

However, music can also become a source of irritation and become a noise for someone who is unaccustomed and annoyed by it. As per law, the quantitative noise is defined functionally as regards to the sound’s intensity level to determine the extent to which it could be acceptable or not. The problem with the legislation law is finding out the right level above which the sound becomes unacceptable enough to be considered as noise. (Traux, 95) The noise pollution should be considered by the duration of the sound, the frequency of noise, and whether there is any control to the sound or not. The British Columbia Workers’ Compensation Board (WCB) has fixed the limitations of sound to be 85 decibels in the workplace and above it is harmful. If sound reaches 120 decibels, it becomes very painful and at 140, it is very harmful. However, at home the noise level above 50 decibels is quite normal and above 55 is serious. While in hospitals and schools, the safe level of sound is 35 decibels. (Ban the Canons, Online) The noise if reaches above the safe level cause tremendous impact on health like increase in stress, high blood pressure, loss of sleep, inability to concentrate and learn and loss of productivity. Noise pollution can impair hearing in children; reduce their attention level and cause negative impact on them.

We are staying in British Columbia and near the villages where farmer’s blast their cannons from dawn to dusk and they are very loud. They have the devices like leaf blowers that reciprocate the novel that reaches to the level of 75 or 80 decibels. The noise of the boom cars can reach till 100 decibels, but propane cannons can go to the range of 130 decibels. Though these canons are regulated by the British Columbia, they begin at 6: 30 am and blast until 8: 00 pm. And the areas, which are not regulated, farmers blast their cannons from dawn to dusk. The blast of propane cannons is like a shotgun, ranging between 120-130 decibels. From our home we often have to hear two blasts every single minute and many have to hear five to six blasts every single minute. These blasts occur during the berry season, which stretches from the month of late June to the whole month of October. It is claimed that these propane cannons are neither very necessary nor are very effective and the farmers are breaching the Langley Township Noise Bylaw. (Ban the Canons, Online).

I did some thought-provoking methods to deal with the situation. I along with my neighbors prepared some brochures and campaigning plans and went personally to the farmer’s houses to explain them how much they are causing noise pollution and they should substitute these propane canons with some other method that do not make too much noise and are economically feasible too. Secondly we went to visit the local MLA to personally administer the farmer’s use of propane cannons and govern the farmers towards reducing the noise immersing from the use of cannons. Still the noisemakers are ignoring and bent on using the cannons above the normal decibels. Then I decided to contact the Minister of Agriculture, and the Farm Industry Review Board (FIRB). They have responsibility to pursue the right to Farm Legislation, which has the clause to allow the farmers to the use of the propane cannons. But, if they want they are entitled to modify or make changes in this legislation to check the farmers to control their use of cannons. Many of these issues like that of noise pollution comes under the Vancouver Charter whereby the powers of Council would be exercised by bylaw. The bylaws governing city of Vancouver are numbered beginning with by-law No 1 that is the law, which was enacted first and then continued subsequently. The first by law was passed on 18 th May 1886 and then over many years around 10,000 laws have been passed. The Noise Bylaw of city controls and legalizes construction works, vehicles and noise immersing from households. (SoundSmart, Online) People also formed Urban Noise Task Force. This is a group of citizens, who with the help of the city staff and councilors recommends and makes suggestions to the city for making improvements in Vancouver’s soundscape. There is also on the anvil the Vancouver Transportation Plan. It had proposed that reviews should be conducted on the most important arterial roads in the city for their performance and the way they are dealt with and are being used in relationship to the neighbors. The city is also planning for the quite payment towards most important transportation corridors. The Urban Noise task force has been created to check on the increasing noise in the city and the extent to which it is affecting the daily lives of Vancouver.

In Canada, there are very few laws at the national, provincial, or state levels to govern the noise pollution. As a result, most of the Canadian and EU countries regulations of the law are governed at the municipal level. There are different noise laws and ordinances in municipalities among different areas. The laws constitute certain ordinances that may prohibit persons against creating noise or may place certain guidelines on the level of noise allowed for certain time duration. There is slight difference between the laws in the cities and villages as regards the control of noise pollution is concerned. In cities, there are several laws and governing bodies to check the lawbreakers while in the villages of British Columbia, either MLA can put a control on the noise pollution or there is right to Farm Legislation whose discretion is in the hands of the Minister of Agriculture, and the Farm Industry Review Board (FIRB). Particularly for British Columbia, there is one law, which is the Langley Township Noise Bylaw. For e.g. “the law states that the number of discharges from any noise scare device is limited to a maximum of one discharge in any three minute period of time”. (Noise Control by law 1988 No 2573, Online) The difficulty in the provision of the law is inability on the part of the province to control the direct use of the devices.

Sounds, which exceed the level more than determined, become noise. What makes one sound a noise is determined by the intensity of the volume of sound. It depends on the listening capacity of the people also. For many people what constitutes sound could be noise and for many what is noise is sound and for many, sound is a pleasure. When we look at the day-to-day to life, it is very simple to determine what constitutes sound and what constitutes noise. For e.g. when we listen to the music, it would sound very appealing to the ears and give soothing effect and if this music is interrupted by the other sounds like unnecessary playing of drums, or shouts of children or sounds of traffic on the roads, it would become a noise, which could be very irritating. But it is very difficulty to consider the same in case we have to determine sound and noise in theoretical terms and on the basis of its established set norms and prescribed limits. The legislation of each area or place has considered the proximate level of sound and if the sound reaches above that level, it becomes noise requiring strict consideration. The problems come in legislation in determining the nature of sound and in determining if really this sound is noise. If someone is typing something on a typewriter, it could be very annoying to someone even if its sound is low. It is also not necessary that unpitched sound is noise; it could be a sound from music as well.

The Truax model understands the relationship between the listener and the sound. This model describes the relationship between the listener and its environment, which is interfered with the help of the sound and triangular relationship, is therefore created. Any change occurring due to any one of the components either due to habituation, or any other disturbances has an effect on the soundscape and that what happened in this process.

The above example I cited is related to the environmental acoustics. “This acoustics studies show different frequencies behave during propagation. When the sound waves comes into contact with objects, its energy is transmitted through the object, absorbed within it, or reflected from it with varying degrees of efficiency depending on efficiency.” (Traux, 5) This happens when the cannons blow. They reciprocate the sound waves above the level prescribed. These sounds create a disturbance between the relation between the listener and its environment.

Every now and then we are facing the noise pollution and as it is difficult to analyze, more difficult is to follow the legislation. In Canada, the noise pollution is controlled at the Federal, provincial and municipal levels and government has adopted different roles and responsibilities as regards to the noise pollution issues. For e.g. Federal government has responsibility for ensuring noise pollution does not occur in case of consumer products, equipment, and vehicles. But, these regulations do not follow when these products are sold and after they are used and depleted. The sold and depleted products often exceed the prescribed sound levels, for which federal government is not responsible. The federal government has also mentioned about the guidelines for control of pollution through provincial transportation systems including aircraft, trains and waterways. As a part of its provincial role, government fixes rules in the area of land use planning. They help the municipalities in pursuing the noise control by-laws to decrease the sources of noise pollution. They also have provisions to check the noise levels immersing from consumer products, equipments and vehicles. And in municipal level role too, municipalities see to it that noise control bylaws are followed adequately in the provincial areas. (CBC News, Online).

The complexities of the noise immersing from the different corners of our lives create hurdles in the path of the government at different levels for effective application of the legislation.

Negative effects of noise pollution essay sample, example.

Image: freepik.com

Industry growth, an increasing number of vehicles and constant information overload causes a significant and underestimated problem: noise pollution. The term noise pollution is used to define unwanted sounds that are released into the environment. Various research studies have proven that noise pollution imposes a number of negative impacts on mental and physical health. To understand the reasons behind these health conditions, people should consider the effects that are usually caused by noise pollution.

In a modern megalopolis, noise pollution arises from many sources, such as traffic, barking dogs, noisy neighbors, aircraft, verbal advertising in streets, and many other environmental factors merging into one sound wall. A person may get used to perceiving these sounds and ignore them, but on a subconscious level, such constant noise exposure has a significant effect. Noise pollution is measured in decibels, and its intensity and duration determines the impact on an individual’s health.

One of the most obvious negative consequences of prolonged exposure to noise is hearing loss. Studies show that people who have been regularly exposed to intense noise, due to the nature of their work, have decreased hearing sensibility compared to those who have worked in more quiet conditions. The most disturbing source of noise pollution stems from traffic (Healthy Hearing). Elevated sound levels cause changes in the structure of the inner ear, which results in irreversible hearing loss.

Another negative effect caused by noise pollution is heightened irritability and sensitivity. Different sounds can have different impacts on a person; thus, one can get annoyed with the sound of water dripping from a faucet or car horns blowing, but relax to the sounds of falling rain. Natural sounds are much less irritating than artificial sounds, such as traffic noise. However, natural sounds also create a sound wall effect as in the case of a waterfall or the wind blowing. In contrast, living near the motorway can lead to frustration and can seriously upset human nerves.

Speech and sleep interference is another issue that arises from noise pollution. It can be difficult to talk while standing on a busy street, and in this case, people often have to shout to be heard. Therefore, hearing and interpreting each other becomes an issue. The noise of a big city is one of the most popular reasons for sleep disorders. High levels of noise often wake people in the middle of the night and hinder them while trying to fall asleep again, thus breaking bio-rhythms and causing weakness and drowsiness during the next day.

Decreased work performance should also be mentioned in the list of negative impacts caused by noise pollution. High levels of noise can cause inaccuracy and inattentiveness, which can result in decreased productivity and additional stress. This is a crucial point for people whose workplaces are potentially dangerous, such as construction sites or factories. A misheard order or instruction, or the lack of concentration in such workplaces can lead to severe consequences.

It can be observed that noise pollution is a serious, though underestimated problem for the human population. It causes a number of negative effects both on health and the effectiveness of performing actions. Among the most obvious and significant negative effects are hearing loss, increased irritability, speech and sleep disturbances, and decreased work performance. Even if a person becomes accustomed to constant noise and thinks that it does not affect them, changes still occur. Every individual, including scientific and healthcare organizations, should seek ways to minimize the aforementioned impacts and reduce their exposure to noise pollution.

300 Words Essay on Noise Pollution

Noise pollution is a pervasive and often underestimated environmental issue that has a significant impact on the quality of life in urban areas. It refers to the excessive, unwanted, and disruptive sounds that fill our surroundings, leading to a wide range of physical, psychological, and social problems.

Sources of Noise Pollution

One of the primary sources of noise pollution in urban settings is traffic. The constant roar of engines, honking horns, and screeching brakes can be overwhelming. Industrial activities also contribute significantly, with the relentless hum of machinery and construction sites adding to the cacophony. In addition to these, social and recreational activities, such as concerts, parties, and even barking dogs, can add to the noise burden.

Consequences of Noise Pollution

The consequences of noise pollution are far-reaching. Physiologically, exposure to high noise levels can lead to hearing loss, elevated stress levels, and an increased risk of cardiovascular problems. It can disrupt sleep patterns, leading to chronic fatigue and irritability. Noise pollution can also impair cognitive functions and hinder concentration, impacting productivity and academic performance .

Moreover, noise pollution has social implications. It can strain relationships among neighbours, causing conflicts and reducing the sense of community. Children growing up in noisy environments may experience delays in language development and learning difficulties. Additionally, it affects wildlife, disrupting their natural habitats and communication.

How to Reduce Noise Pollution

Addressing noise pollution requires a multifaceted approach. Urban planning and zoning regulations can play a crucial role in minimizing noise exposure for residents. The development of noise barriers, quieter road surfaces, and improved public transportation can help mitigate the problem. Promoting the use of noise-reducing technologies, such as quieter machinery and better-insulated buildings, is also essential.

Individual responsibility is equally vital. Reducing unnecessary honking, limiting loud activities during nighttime hours, and using noise-cancelling headphones are practical steps individuals can take to reduce their contribution to noise pollution.

In conclusion, noise pollution poses a growing threat to urban life, affecting physical and mental health, social harmony, and overall well-being. To combat this issue effectively, a combination of government regulations, technological advancements, and individual awareness and responsibility is needed. 

500 Words Essay on Noise Pollution

Introduction.

Noise pollution encompasses unwanted and disruptive sounds generated by various sources, including transportation, industrial activities, and recreational events. 

This essay explores the causes, effects, and solutions to noise pollution, emphasizing the pressing need for collective action to mitigate its adverse impact on modern urban life.

Causes of Noise Pollution

1. Transportation: Urban areas are characterized by constant traffic flow, which is a primary source of noise pollution. The incessant rumble of engines, screeching tires, and incessant honking contribute significantly to the overall noise levels.

2. Industrial Activities: Industries and factories, often concentrated in urban zones, generate noise through the operation of heavy machinery, equipment, and manufacturing processes. Construction activities, with their bulldozers and pile drivers, are particularly notorious for their noise emissions.

3. Recreational Activities: Urban centres are hubs of entertainment and recreation, hosting concerts, sporting events, and social gatherings. These activities generate high levels of noise, especially when amplified music or cheering crowds are involved.

Effects of Noise Pollution

1. Health Implications: Prolonged exposure to high noise levels can lead to severe health problems. Hearing impairment is a common consequence, with noise-induced hearing loss being a well-documented issue. Noise pollution is also linked to increased stress, anxiety, and elevated blood pressure, which can escalate the risk of cardiovascular diseases.

2. Sleep Disturbances: Noise pollution disrupts sleep patterns, leading to chronic sleep disturbances. Poor sleep quality can result in fatigue, irritability, and decreased cognitive performance, affecting overall productivity and well-being.

3. Cognitive Impairment: Noise pollution impairs cognitive functions, making it difficult to concentrate and focus. This can hinder academic performance and reduce workplace productivity.

Solutions to Noise Pollution

Noise Pollution Essay

When noise levels exceed the normal range, this is known as noise pollution. When noise levels exceed safe levels, it becomes harmful to living things. Additionally, these irritating noises disrupt several activities and imbalance the surroundings. Here are a few sample essays on the topic ‘noise pollution’.

100 Words Essay On Noise Pollution

Noise Pollution is regarded as a form of environmental pollution brought on by excessive noise from various sources. The term "noise disturbance" also applies to noise pollution. In addition to being unhealthy, excessive noise can disturb animal or human life. Although there is a significant environmental problem in India that requires adequate attention to be resolved, noise pollution is less dangerous than pollution of the water, air, and soil. Machines, transportation systems, poor urban planning and other factors contribute to outdoor noise.

Among the sources of indoor noise include domestic appliances, construction activity, loud music, etc. The most frequent disability brought on by noise pollution is irreversible hearing loss due to ear drum damage.

200 Words Essay On Noise Pollution

Average noise levels are required for daily life, but undesirable noise or noise that is intolerable to people, animals, or plants results in noise pollution in the environment. Noise is a term used to describe the undesired sound produced by many industrial or non-industrial sources that are employed in our daily lives. High-volume sound has detrimental impacts on one's health, especially the ears.

The marine animals, especially whales and dolphins, who rely on their hearing to communicate, find food, defend themselves, and survive in the water, are significantly harmed by high levels of noise, suffering from physical trauma, injuries, bleeding around the brain, large bubbles in organs, and even death. Navy submarine sonar, which can be heard from about 300 miles away, is the cause of the noise in the ocean. The long-term effects of noise pollution are becoming more hazardous and concerning.

Prevention | There are various ways to prevent noise pollution, including encouraging soundproof rooms. Contractors should keep the construction in the industrial sector, industries, and factories away from residential buildings. Damaged exhaust pipes on motorcycles should be repaired.

Government should ban noisy vehicles, airports, bus and train stations, and other transportation hubs should be kept away from residential areas. People should establish quiet zones near educational institutions and hospitals, and more vegetation should be permitted alongside roads and residential areas to reduce noise pollution by absorbing sound.

500 Words Essay On Noise Pollution

The spread of noise with varying implications on human or animal activities is known as noise pollution, also known as environmental noise or sound pollution. Machines, transportation, and propagation systems are the main global sources of outdoor noise. Noise pollution is carried on by numerous noise sources, both industrial and non-industrial, and it impacts the health of people, plants, and animals in many ways. The lives of current and future generations are in great danger due to noise pollution's steadily rising level.

Sources Of Noise Pollution

Regular social gatherings like weddings, parties, pubs, clubs, discos, or houses of religion, among others, disturb the neighborhood.

Regular construction projects, such as mining and building bridges, dams, stations, highways, and flyovers, entail large machinery that produces a lot of noise.

All industries, large and small, use massive machinery that produces high pitch sound in large quantities, endangering our health and lives. Other machinery used in factories and businesses, such as compressors, generators, exhaust fans, and grinding mills, also makes a lot of noise.

Effects Of Noise Pollution

Because of the undesired sound, noise pollution can lead to various hearing issues, including ear drum damage and hearing loss.

It lowers the ear's receptivity to the sounds needed to control body rhythm.

Aggressive behaviour, disturbed sleep, stress, weakness, exhaustion, hypertension, cardiovascular diseases, and other severe and chronic health problems in later life are all consequences of noise pollution on psychological health.

It causes communication issues and miscommunication. It impacts animals and increases aggressiveness in dogs.

Marine life and animals are particularly vulnerable to noise pollution. Their behavior may change as a result of it affecting their listening abilities. During migration, these animals have trouble listening, which can negatively affect their survival. When it comes to marine life, noise pollution can cause physical and internal harm.

Legal Aspects Of Controlling Noise Pollution

The government may use a conditional or permanent order to eliminate a public nuisance under Section 133.

Limits for noise exposure in the work zone are outlined in the Factories Act Reduction of Noise and Oil of Machinery.

The Motor Vehicle Act deals with changing faulty engines and using the horn.

Preventive Measures For Noise Pollution

Public awareness should be raised to regulate the hazardous sound level in the environment, and everyone should take the regulations seriously.

Reduce the usage of high-pitched sound generators inside and outside the home, such as at parties, clubs, pubs, and discos.

Planting trees can reduce the noise generated by moving from one location to another, which is another helpful measure.

We must take responsibility for refraining from needless honking. We can reduce noise pollution if strict measures are implemented against those who break this regulation.

Additionally, constructing soundproof walls, windows, and flyovers in homes, buildings, and overpasses can reduce noise.

As noise pollution levels rise, there is an urgent need for greater public awareness of its sources, effects, and preventative measures. In workplaces, schools, neighborhoods, hospitals, etc., excessive noise levels should be prohibited. The issue of noise pollution should be covered in textbooks, and lectures and discussions should be held in educational institutions to create more informed and socially responsible future generations.

Metrics details

Environmental movements of the late 20th century resulted in sweeping legislation and regulatory actions to reduce the prevalence of diverse pollutants. Although the consequences of noise pollution to public health, environment, and the economy have been recognized over the same time period, noise has received far less policy attention. Correspondingly, even while evidence of the diverse and detrimental effects of noise pollution on human health has grown, solutions and actual reductions in environmental noise remain seemingly out of reach.

To address this shortcoming, we developed a prospectus for environmental noise reduction through technology-forcing policies. Technology-forcing describes intent to encourage technological solutions for pollution control through policy and regulations, and has been a critical component of national and global progress in reducing environmental pollutants.

We take advantage of the unique policy history for noise in the United States - which initially enacted, but then abandoned federal noise regulation. We compare this history against outcomes from contemporaneous environmental legislation for air, water, and occupational pollution control, to demonstrate the potential for technology-forcing to reduce noise pollution. Our review then identifies promising solutions, in the form of existing technologies suitable for innovation and diffusion through technology-forcing regulations and incentives.

Based on this review, we outline a program for noise policy development to support efforts to reduce environmental noise pollution worldwide. The proposed program consists of three steps, which are to (i) identify dominant sources of noise pollution, (ii) combine legislative or regulatory provisions with suitable systems of enforcement and incentives, and (iii) anticipate and prepare for stages of technological change.

Impact statement

Analysis of noise policy often focuses on justifying the need to reduce noise pollution. In this article, we demonstrate how technology-forcing regulations could also promote much-needed innovation and diffusion of technologies to reduce environmental noise pollution. We first establish the potential for technology-forcing by comparing technology outcomes from environmental legislation passed contemporaneously to the inactive US Noise Control Act. We next review promising innovations available for diffusion in multiple sectors to reduce environmental noise. Lastly, we recommend a program to support development of technology-forcing noise policies, to help ensure that the benefits of reduced noise pollution are distributed equitably.

Noise Pollution Essay

Introduction.

Do you get irritated when someone honks their car horn while waiting for the traffic signal to turn green? Will you be able to concentrate on your work/studies when heavy construction is taking place near your house and the drilling sound deafens you? These are some of the instances of noise pollution, and we will be discussing more in this noise pollution essay.

Causes of Noise Pollution

There are various factors that cause noise pollution in the environment, and we will understand them through this short essay on noise pollution. We know that technology has eased the life of humans through grinders, compressors, televisions, generators etc., but we are not aware that this same technology is ruining our health. Along with these machines, there are also cars, bikes, buses, trains and aeroplanes that produce a large amount of noise. We will see how this creates pollution through this noise pollution essay.

People unnecessarily use horns, and the long siren disturbs other people. Besides, people play music at a loud volume while travelling in cars or buses. Due to this, we put others in an inconvenient position. It is only required to think of the commotion that happens during weddings and other festivals and how it causes a nuisance to those residing nearby to understand the seriousness of the matter. The noise pollution essay in English is, therefore, an attempt to throw light on this issue.

Ways to Reduce Noise Pollution

Noise pollution is a serious concern, and hence, we must try to prevent it. But before we see how it can be controlled, we will see its effect on us in this short essay on noise pollution. Noise pollution causes hearing problems if we get exposed to a high volume of sounds continuously. It also has the potential to damage our eardrums, resulting in permanent loss of hearing.

Moreover, it disturbs our state of mind, and we might experience stress, tension, loss of sleep etc., thus affecting our psychological health. All these reasons point out that noise pollution can be dangerous and we must follow certain measures to prevent it.

First of all, we must be responsible for not honking unnecessarily. If strict actions are taken against the violators of this rule, we can reduce noise pollution to some extent. Besides, installing soundproof walls and windows in houses, buildings and flyovers can also help in bringing down the noise level.

Planting trees is another effective measure as we can reduce the noise from travelling from one place to another. So, children can write an essay on noise pollution 150 words by taking important points from the noise pollution essay in English and thus creating awareness regarding the issue.

• Noise Pollution Essay

Essay on Noise Pollution

Noise pollution is one of the types of pollution we face daily. Like air pollution, water pollution, soil pollution and other types, noise pollution has a major impact on our health. Atmospheric pollution is not the only pollution we go through, but noise pollution can bring destruction to our lives. According to the World Health Organization, noise pollution is a dangerous health issue. The European Environment (EEA) says noise pollution is responsible for 16,600 premature deaths in Europe alone.

A person continuously facing noise pollution can start meeting health issues and can be dangerous in the long term. Several unpleasant noise distractions can bring problems later in life.

Cities have become noisier with car honking, loudspeakers; traffic, etc. leading to noise pollution. Construction of roads, buildings, apartments and other areas are also resulting in increased noise pollution.

What is Noise Pollution?

According to the WHO, noise pollution is a noise above 65db, which can severely affect both humans and animals. A noise beyond 75 dB can be painful and will affect the person severely.

It is impossible to see the danger posed by noise pollution. On land and under the sea, you can't see it, but it still exists. Humans and other organisms can be affected adversely by noise pollution if it is an unwanted or disturbing sound.                     

A decibel is the measurement of sound. Rustling leaves (20-30 decibels) or thunderclaps (120 decibels) to the wail of sirens (120-140 decibels) are all sounds that occur naturally in the natural environment. If a person hears sounds whose decibel level reaches 85 decibels or higher, their ears can be damaged. The sounds of lawnmowers (90 decibels), trains (90 to 115 decibels), and rock concerts (110 to 120 decibels) are just a few familiar sources that exceed this threshold.

The presence of noise pollution has a daily impact on millions of people. Hearing loss caused by noise is the most common health problem caused by noise exposure. Furthermore, loud noise can also lead to health problems such as hypertension, heart disease, sleep disturbances, and stress. All age groups are susceptible to these health problems, especially children. It has been shown that children living near loud airports and busy streets suffer from stress and other problems, such as memory problems, attention difficulties, and difficulties with reading.

Animals are also adversely affected by noise pollution. Caterpillars' hearts beat faster when loud sounds are made, and bluebirds have fewer chicks when loud noises are made. There are many reasons animals utilize sound, including to navigate, locate food, attract mates, and avoid predators. The noise pollution they encounter affects their ability to accomplish these tasks, affecting their survival.

Noisy environments are not only harming animals on land, but it is also getting worse for animals in the ocean. A once tranquil marine environment has become loud and chaotic because of ships, drilling devices, sonar, and seismic surveys. The negative effects of noise pollution are felt particularly by whales and dolphins. For marine mammals, echolocation is essential for communication, navigation, feeding and mate-finding. Excessive noise can interfere with echolocation.

It is the naval sonar devices that produce the loudest underwater noise. The use of sonar works similarly to echolocation in that sound waves are sent down into the ocean and bounce off objects, returning echoes to the ship that can pinpoint the object's location. Whales' ability to use echolocation is interfered with when they hear sonar sounds, which can reach 235 decibels and travel hundreds of miles under the surface. Research has shown that sonar can make whales strand on beaches and alter the feeding behaviour of blue whales (Balaenoptera musculus), which are endangered. Groups representing the environment have called on the U.S. Department of Defense to discontinue or reduce sonar-based military training.

Furthermore, hydrographic surveys can cause loud explosions from inside the ocean. Deep in the water, oil and gas are found using air guns that send sound pulses onto the ocean floor. There is potential for marine animals to be harmed by the sound blasts and to suffer serious damage to their ears. Additionally, the whales may also change their behaviour as a result of this noise. 

In Spain, bioacoustics researcher Michel Andre is studying the effects of noise pollution with the help of hydrophones. He has gathered data from 22 different locations during his project, LIDO (Listening to the Deep Ocean Environment). Using computers, the lab identifies 26 different species of whales and dolphins, including sounds produced by humans. In the analysis, underwater noise will be investigated for its effect on these animals.

What causes Noise Pollution?

Although the world is turning into the use of technology, at the same time, this technology is also harmful. Industries using compressors, exhaust fans, and generators are producing a lot of noise.

Similarly, bikes and cars with old silencers produce heavy noise that can lead to pollution. Planes, heavy trucks and buses are also part of this noise pollution. Low flying aircraft, especially military ones, causes noise pollution. Similarly, submarines can cause ocean sound pollution.

How Noise Pollution affects a Person?

Noise pollution can primarily start affecting the hearing ability of the person, causing permanent hearing impairment. Furthermore, it can cause an increase in blood pressure, hypertension, and other stress-related health issues. In many cases, noise pollution can cause a disturbance in a person's state of mind, which further causes disturbance in sleep patterns, stress, aggressiveness, and other issues. The psychological health of the person can also get disturbed due to regular exposure to noise pollution.  Noise above 45 dB can disrupt the pattern of your sleep. According to the WHO, the noise level should not be more than 30db. Change in the sleep pattern can also bring change in your behaviour.

If you have pets in your home or around your area, then noise pollution can bring a negative impact on the environment. Firecrackers can bring fear in them if they are regularly exposed to them. This will also bring change in their behaviour.

Effect on Wildlife and Marine Life

Animals and marine life are vulnerable to noise pollution. It can affect their listening skills, which further affects their behaviour pattern. These animals find it hard to listen during migration, which can negatively affect their lives. When it comes to marine life, noise pollution can lead to internal damage like physical problems in them.

Measures for Noise Pollution

There are many measures taken by the government and people to reduce the effect of noise pollution. Soundproof walls and windows are now being installed in many houses. Many flyovers in cities have soundproof walls to bring down the noise level to a nearby resident from vehicles running. As responsible citizens, we must contribute towards bringing down noise pollution. Needless honking should be stopped and officials should fine people doing it heavily. Hospitals and schools are built-in silent zones.

There should be rules to avoid noise in residential and sensitive areas. People need to be aware of health hazards from noise pollution.

One of the best ways to bring down noise pollution is by planting more and more plants. This process of planting trees can help to reduce the travelling of noise from one place to another.

Noise pollution is the most common problem faced by humans, thanks to various reasons that push many people to face health issues. Following standard measures can be helpful in the long term for both humans and the environment. The ultimate aim is to bring down noise pollution for a better environment.

Noise Pollution: Impact on Human Health

There are several ways in which noise pollution can harm human health:

Having an elevated blood pressure for a long period directly results in hypertension, which is caused by noise pollution.

Hearing loss occurs whenever humans are repeatedly exposed to sounds that exceed what their eardrums can handle, resulting in permanent damage to their hearing.

To function properly at work, it is necessary to get enough sleep every night. Sleep disorders affect energy levels throughout the day. Pollution causes disturbance in sleep cycles, which in turn results in irritation and unrest.

Heart issues such as blood pressure level, stress and cardiovascular diseases can arise in a healthy individual, but a person suffering from heart disease may experience a sudden increase.

It will affect your mental health also very badly because continuously hearing the noise this much loud will pressure your eardrums and that will badly affect your brain also

FAQs on Noise Pollution Essay

Essay on Noise Pollution

Essay generator.

In the modern world, the cacophony of sounds from vehicles, industrial activities, and urban development has become a constant backdrop to our lives. This relentless barrage of noise constitutes what we know as noise pollution, an environmental and public health issue that is often overshadowed by other forms of pollution but is equally potent and destructive. This essay delves into the depths of noise pollution, unraveling its causes, impacts, and potential solutions, aiming to shed light on an issue that is powerful in its ability to affect human health, wildlife, and the environment.

Noise Pollution

Noise pollution is defined as any unwanted or harmful sound that disrupts the natural balance and creates potential harm to human and animal life. The World Health Organization (WHO) has identified noise pollution as the second-largest environmental cause of health problems, just after the impact of air quality. From the incessant hum of traffic to the roar of airplanes overhead and the clamor of construction sites, noise pollution surrounds us, often so pervasive that many have become desensitized to its presence.

Causes of Noise Pollution

The sources of noise pollution are manifold and predominantly stem from urban development and human activities. Key contributors include:

• Transportation Systems: The roar of vehicles, trains, airplanes, and ships are amongst the most significant sources of noise pollution, especially in urban areas.

In 2011, an estimated one million healthy life years were lost from traffic-related noise in the western part of Europe only. Important sources for environmental noise exposure are road, railway and air traffic, or building sites. Noise exposure can also occur through other sources such as wind turbines, and leisure activities such as listening to loud music or other audio content including participation in e-sports (video and computer game competitions). Excessive noise can cause annoyance; in addition research shows it increases the risk for IHD and hypertension, sleep disturbance, hearing impairment, tinnitus and cognitive impairment, with increasing evidence for other health impacts such as adverse birth outcomes and mental health problems.

Essay on noise pollution: sources, effects and prevention.

Essay on Noise Pollution: Sources, Effects, Prevention and Control of Noise Pollution!

The word ‘Noise’ is derived from the Latin word ‘nausea’ which means feeling of sickness at the stomach with an urge to vomit. The term noise may be defined in a number of ways.

ADVERTISEMENTS:

For example:

(i) In acoustic, noise is defined as unwanted, unpleasant and annoying sound.

(ii) Noise is defined as unwanted, unpleasant, disagreeable sound that causes discomfort.

(iii) Noise is defined as the wrong sound, in the wrong place at the wrong time.

(iv) Noise is the sound incidental to our civilization and is without agreeable musical quality.

It is seen that a particular sound which is musical to some­one, may be noise to another. However, if the sound is loud and it prolongs for a longer period of time, it becomes noise for all. (The technological advancements such steam engines, diesel en­gines, jet engines, industrial machinery, traffic noise of moving trucks, buses, cars, and automobiles with blow horns, etc. are polluting the atmosphere with their continuous noise.

So, now a day’s noise is considered as a component of environmental pol­lution having a potential to cause hazards to human health and communication.) It may be noted that sound is a pure tone, harmonically related, occurring at regular intervals and producing meaning full communication whereas noise is a complex mixture of a number of pure tones of varying frequencies and amplitudes.

Noise pollution may be defined in a number of ways:

(i) According to Odum, noise pollution is the unwanted sound dumped into environment without regard to the adverse effect it may have.

(ii) Noise pollution may be defined as any unwanted elec­tromagnetic signal (sound) that produces a jarring or dis­pleasing effect and which interferes with human com­munication, comfort and health.

(iii) According to Ambast (1988), noise pollution is caused when the loudness of the sound becomes irritating or unbearable.

(iv) Noise pollution also refers to perturbations which inter­fere in the communication systems.

The unit of sound intensity is decibel (dB). The sound inten­sity from 0 to 100 dB is pleasant but when the sound intensity exceeds 120 dB, it causes noise. Sound intensity of 130 dB is the upper limit of the threshold of hearing and beyond this, is the threshold of pain which may cause damage to car and leading to hearing impairment. So, sound of more than 130 dB causes noise pollution.

1. Sources of Noise Pollution :

Noise may originate either from natural sources or from anthropogenic activities. The natural sources of noise include thunder, cyclone, roaring of sea, etc. The manmade noise are mechanized automobiles, industries, trains, aero planes, social functions etc. It may be noted that the manmade noise is now doubling after every decade.

Broadly speaking, the noise may be classified into:

(1) Transport noise;

(2) Industrial noise; and

(3) Neighborhood noise.

1. Transport noise:

The main threat of noise comes from transport sector. The transport noise includes road traffic noise, rail traffic noise and aircraft noise.

(a) Road traffic noise:

The chief causes of road traffic noise are the number of road vehicles and their high traffic speed. Faster moving vehicles produce high noise from their gear box, exhaust system, vibrations from their body, etc.

(b) Rail traffic noise:

The noise from rail traffic is compara­tively lower than that from road traffic. Introduction of diesel engines or electrical engines has reduced the in­tensity of rail traffic noise which was previously shown by steam engine. Besides use of welded tracks and im­proved coach suspension have contributed to the reduc­tion in railways noise,

(c) Aircraft noise:

Larger and faster aircrafts produce high noise intermittently during takeoff, landing and during flight. Noise generates from compressor and turbine and near jet exhaust. Jet engines create most noise around a radius of 16 km. Sonic boom is an important aspect of aircraft noise. Sonic boom occurs when an aircraft flies supersonically overhead.

(2) Industrial noise:

The different machines of numerous industries, factories and mills produce a lot of high intensity sounds causing noise pollution. Some industrial processes like weaning, ship building, boiler making, pressing and blasting op­erations are more nosier than others.

The operations in pneu­matic drills, milling machines, cutters, printing press with an up­ward, downward and sideways movement and vibrations, cause lowering of hearing capacity to a large extent.

The noise pollution is further magnified due to the installation of industries in com­pact places. For example, the workers near the heavy industrial blowers in steel industry are exposed to sound of 112dB for eight hours and hence suffer from occupational pollution. Some typi­cal industrial noise levels are given in table 10.1.

Table 10.1: Some Typical Industrial Noise Levels

3. Neighborhood noise:

This type of noise includes antisocial activities of neighbors like using of loud TV, stereo, radio sets, jazz music, fireworks parties, playing of children, bark­ing of dogs, neighborhood brawls out of intoxication and indus­trial neighborhood noise etc. The machines used in house con­struction like concrete mixes, vibrators, bulldozers, heavy diesel lorry, building demolition activities also add to the noise pollu­tion.

The central pollution board (India) has prescribed permissible sound levels for cities, divided into four zones as given in table 10.2.

Table 10.2: Permissible Sound Levels As Prescribed By Cen­tral Pollution Control Board.

2. Effects of Noise Pollution :

Noise is air-borne mechanical energy striking the human eardrum. A sound of 65dB is the noise level for con­versation heart at a distance of one meter. A sound of 125dB (A) gives the sensation of pain in the ear and 150dB (A) might kill a human being. If a noise of 90dB in the mid-frequency range reaches the ear for more than few minutes, then the sensitivity of the ear is reduced.

The various effects of noise pollution on human beings may be classified in to two categories:

(1) Auditory effects; and

(2) Non-auditory effects.

1. Auditory effects:

The impairing of hearing which may cause immediate auditory fatigue finally leading to deafness is known as auditory effects.

2. Non-auditory effects:

These effects include interference with speech communication, annoyance leading to ill-temper, bick­ering, mental disorientation, violent behavior and a series of health hazards.

In addition to serious loss of hearing, noise also causes patho­logical (or psychological), non-pathological (or physiological) and vibrational disorders.

(a) Pathological disorder:

(i) Exposure to high frequencies or ultrasonic sound above the audible range damages inner ear and induces nau­sea and dizziness in man.

(ii) Exposure to mid-audible frequency affects brain and nerv­ous system having significant impact on thinking and coordination of limbs.

(iii) Moderate vibration can lead to pain, numbness and cyanosis (blue coloration) of Fingers.

(iv) Severe vibration results in damage to bones and joints in the hands with swelling and stiffness.

(v) Exposure to low frequency noise can reduce heart beat, variation in blood pressure and breathing difficulties.

(b) Non-pathological disorders:

These disorders are mainly seen in industries and other establishments which result in lower efficiency, reduced work rate, increased absenteeism and a higher potential for accidents and injuries. Noise also disturbs sound sleep of old people. Children exposed to excessive noise show signs of behavioral disorder which in later age manifest them­selves in destructive nature.

(c) Vibration (physical vibration) disorder and Reynaud’s phenomenon:

(i) Noise from constant vibrations of hand tools like the hammer or drilling instrument creates ‘dead hands’ or ‘white fingers’ which is known as Reynaud’s pheno­menon.

(ii) Noise from moderate vibrations causes pain, numbness, and cyanosis.

(iii) Noise from severe vibrations causes damage to bones, joints with swelling and stiffness.

Some of the important effects of noise pollution are outlined as given below:

1. It causes contraction of blood vessels, makes the skin pale leads to excessive secretion of adrenaline hormone into blood thereby inducing high blood pressure.

2. It may cause damage to heart, brain, kidney and liver.

3. It induces contraction of muscles which ultimately leads to nervous breakdown, tension and even insanity.

4. It induces anxiety, stress and fright which in turn causes increased heart beat, constriction of blood vessels, dilation of pupil of eye etc. by modulating the hormone content in blood.

5. It damages some part of auditory system thereby causing the impairment of hearing.

6. Excessive noise causes thickening of blood and changes in breathing amplitude.

7. It is responsible for disturbing the entire biological system. For example, the internal wreckage caused by the roar of a jet engine includes gastric ulcer and thymus gland atrophy.

8. It causes irritation, dissatisfaction, disinterest and affects work efficiency.

9. Sudden and explosive sounds cause cracks in buildings and breaking of window doors and glasses.

10. It causes chronic headache and irritability thereby reducing work efficiency.

11. It brings about changes in the behavioral aptitude of birds and animals. For example, noise pollution discourages the annual visit of migratory birds to Alipore Zoo of Kolkata.

12. It interferes with communication systems. For example, sometimes it becomes necessary to raise the volume of our TV set or radio to overcome the impact of external noise.

The detrimental effects of noise with different intensity on human beings are shown in Table 10.3.

Permissible Noise Levels (Control) :

We have already discussed the sources of noise of different in­tensity and their hazardous impact on living organisms particu­larly on man. Still we work and live in the environment where the noise level is not optimum. Thus it is rightly told by Robert Koch that noise pollution is a slow agent of death. The peoples work­ing in areas where the intensity of noise is comparatively higher suffer from progressive hearing loss, physiological (health) and psychological hazards including tension. The maximum permissible noise levels at different situations are summarised in Table 10.4.

3. Prevention and Control of Noise Pollution :

Noise produced from different sources has created a catastrophe to the entire living world specially to man. Hence, necessary steps should be taken to minimise the level of noise thereby protecting the living world from its detrimental effects.

Few methods of minimising noise pollution are discussed below:

(1) Industrial noise pollution control:

The level of noise pollution due to industries can be lowered down by adopting the following techniques:

(a) Use of improved technique:

The noise at source can be reduced by replacing noise producing machines with suitable improved technique. For example, the noise from exhaust fans can be decreased either by increasing the number of blades or by decreasing the rotational speed.

(b) Sound proofing:

An insulating material may be applied on the noise producing machinery and equipment’s which causes sound proofing.

(c) Transmission control:

The level of noise can be mini­mised by covering the walls of the room by sound ab­sorber (e.g. acoustic tiles), introducing gaskets around the doors and windows, sealing all the outlets and putting carpet, drapery and acoustic materials inside the room.

(d) Creation of green vegetation cover:

Plants and trees should be planted along highways, streets and indus­trial areas because the vegetation covers absorb and dis­sipate sound energy and acts as a buffer zone.

(e) Using protective devices:

The use of ear plugs or ear muffs or even cotton balls by the worker in the industry can protect them from hazardous effects of noise pollu­tion.

(f) Operations in open space:

Noisy industrial operations should be conducted at open spaces far off from resi­dential areas.

(g) Use of Building codes:

Certain codes should be en­forced which require sound proofing in the construction of industries, buildings and apartments.

2. Community noise control:

The community noise control includes minimization of noise from air traffic, transport system, building constructions etc. The noises from the above sources can be lowered by adopting the following procedures:

(a) The air traffic noise can be reduced either by suitable technique or by zoning the area around the airport and not allowing for the construction of houses or indus­tries within 10 meters of the airport.

(b) The road traffic noise includes tyre noise, engine intake noise, exhaust noise, aerodynamic noise, noise from blowing of horns etc. Such type of noise pollution can be controlled by incorporating silencers in vehicles, main­taining speed limit prescribed for the vehicle and ban­ning air horns.

(c) The loudspeakers, radio and music system should be operated at threshold intensity so that the noise level should not be hazardous to living organisms.

(d) Public awareness should be created to educate the com­mon man about the harmful effects of noise pollution, through radio, television, newspapers etc.

(e) The noise can be reduced by introduction of new regula­tions which mainly include lowering speed limits and designing for non-stop operation.

(f) Stringent laws should be implemented to control noise pollution. For example Motor Vehicle Act of India pro­vides restrictions on heavy vehicles using double sirens while passing through populated areas.

(g) The laying of ballast less tracks reduces the noise level due to railways.

(h) The noise pollution can best be controlled by promo­ting education and research.

The use of Battery Energy Storage Systems (BESS) as part of the national Australian electricity grid is rapidly growing due to its ability to bridge the gap between times of energy need and energy generation. Noise emission has emerged as a key environmental impact challenge in the development of BESS in Australia. The key focus of this paper is on the potential of noise reduction through different barrier configurations. Key influencing parameters have been examined to determine the most effective configurations. If a BESS site requires large noise reductions for the development to proceed, this paper provides potential barrier configurations with higher noise reduction potential than the traditional perimeter barrier. Two of the key takeaways from this paper are as follows: First, when selecting barrier configuration, it is important to consider the direction of receivers since it will impact its performance. Second, the barrier configurations that achieve the best noise reduction on average, across the assessed receiver directions and barrier heights, is the combination of having a barrier around the perimeter as well as between the rows. For a 6-meter-high barrier, this configuration has an average noise reduction over double that of a traditional perimeter barrier of equivalent height.
