Impact Of Noise Pollution On Environment – Noise pollution refers to excessive, excessive noise in the environment. It turns out it’s just as dangerous as water or air pollution. Continuous exposure to noise pollution can adversely affect or even damage the hearing facilities of humans and animals. Additionally, it can exacerbate the environmental impact of noise pollution by disrupting animal behavior and ecology.
How does long-term exposure affect us and the environment? This article covers the causes of noise pollution and its many effects on the environment. We also explore the adverse health effects of noise pollution on humans and wildlife.
Impact Of Noise Pollution On Environment
By traditional definition, noise pollution is disturbing, unwanted sound. When unwanted sound interferes with sleep schedules and conversations and disrupts a person’s quality of life, it is considered noise pollution. As cities develop, noise from various sources constantly surrounds us.
Health Hazard Of Noise Pollution
Sadly, state and local governments don’t pay enough attention to noise pollution because it’s not as obvious as air pollution. However, outdoor and indoor noise pollution is a form of air pollution. The only time many of us enjoy a quiet atmosphere is at night, and even then, in urban environments, sirens, traffic noise, and other sounds often permeate the night.
In the European Union, approximately 20% of residents of member states are affected by unhealthy noise. Noise pollution affects people’s living standards, causing an increase in stress hormones.
Environmental noise can lead to sleep disorders, mental health problems and high blood pressure. However, the primary health concern caused by environmental noise pollution is noise-induced hearing loss. Noise pollution also affects various wildlife species.
Traffic noise sources refer to the noise generated by vehicle movement. Traffic noise includes aircraft noise, railway noise and road noise.

Road traffic is always noisy as cars and trucks move from one destination to another. Factors that influence traffic noise include the type of vehicle on the road, the friction between the tires and the road surface, and the behavior and style of the driver.
Railway transportation produces noise, but it is less noisy than road transportation. Train noise comes from engines, warning signals, freight cars and vehicles traveling on the tracks. Aircraft noise is generated by noise caused by various aircraft engines and aircraft structures.
Industrial noise or occupational noise is a by-product of industrial activities. People working in the steel industry or manufacturing plants surrounded by machinery are always surrounded by industrial noise. Occupational noise sources include machinery, buildings and vehicles.
Construction noise results from activities such as demolition, site preparation, construction, expansion, and structural changes. Construction noise levels often depend on the type of construction, its stage and the construction equipment. For example, cleaning and preparing a construction site involves the use of noisy equipment.

Recreational noise, also known as leisure noise, is generated by entertainment activities. Examples of recreational noise sources are parties, religious gatherings, discos, nightclubs and personal listening devices.
Noise pollution mainly affects humans and biodiversity. Therefore, we will discuss the adverse effects of environmental noise pollution on humans, animals, and plants.
Long-term exposure to noise puts human health at risk, with researchers demonstrating the harmful effects of noise pollution. It can cause hearing impairment, cardiovascular disease, annoyance and sleep disturbance.
Continuous exposure to urban noise can lead to hearing loss. Hearing impairment is a disability that affects daily life and personal productivity. People with hearing impairment find it difficult to hear, process and understand speech at low background noise levels.

Hearing problems occur in people exposed to sound frequencies between 500 Hz and 6, 000 Hz. Sound frequencies that may permanently affect your hearing are between 3, 000 Hz and 6, 000 Hz.
However, the World Health Organization states that hearing loss does not occur at 70 dB(A). This means that most people exposed to ambient and recreational noise of 70 dB(A) or less are not at risk for hearing problems.
Even without lifelong exposure, sudden high-pitched disturbing sounds can cause mechanical damage to the inner and outer ears8. The hearing threshold that causes ear damage is 140 dB (A). Exposure to 120 dB(A) may damage children’s ears. Additionally, recording noise at 80 dB(A) can impair hearing function.
Noise pollution can also cause tinnitus, which is a constant ringing in the ears. Tinnitus is most common in people who listen to loud music through headphones, attend concerts, or are constantly exposed to loud sounds. Sometimes tinnitus caused by noise pollution is temporary. Here, it only lasts 24 hours after exposure.

Sleep is an important function of the human body and we cannot ignore it. When we don’t sleep well, human functioning suffers. After a long day of work and high stress, a good night’s sleep can rejuvenate us. People who work the night shift sleep during the day. Lack of sleep hinders brain recovery and cardiovascular system rest time.
However, many people experience sleep disruption due to ambient noise sources, which in turn interferes with their daytime activities, adversely affecting mood and cognitive abilities. People exposed to nighttime noise often suffer from noise that affects their mental state. Due to lack of sleep, they are often grumpy, angry and tired.
One of the effects of noise on human health is high blood pressure. Continuous exposure to traffic noise can lead to high blood pressure, putting you at risk for ischemic heart disease.
A 1997 Chinese study of 20, 000 rural community residents showed that noise determines both systolic and diastolic blood pressure. Caerphilly and Speedwell’s research shows that people who live in areas with average sound levels of 50 and 55 decibels are at risk for ischemic heart disease.

People working in industrial areas experience noise levels of 85 decibels. These people are at risk for high blood pressure. Evidence from a study of Berlin women showed resting levels of epinephrine and norepinephrine. Women whose bedrooms faced a busy street (where at least 20,000 cars passed by each day) had higher levels of norepinephrine.
Children are also at risk for cardiovascular disease. Systolic and diastolic blood pressure are increased in children exposed to traffic noise.
A study of children aged three to seven by Slovak researchers found that children living in noisy areas had higher blood pressure, unlike children living in quiet areas.
The Munich Aircraft Noise Study documents neuroendocrine indices of chronic stress. Researchers found that children exposed to aircraft noise had higher levels of adrenaline and norepinephrine.
Noise Pollution: Causes, Effects And Remedies
Noise pollution affects marine animals across the board. Naval sonar and seismic surveys are extremely dangerous to whales, dolphins and porpoises. Exposure of cetaceans to moderate intensity mid-frequency military sonar can result in multiple deaths and strandings.
As cities grew starting in the 1960s, more powerful sonar was created. These sonar were responsible for the mass stranding of more than 40 Habitat’s beaked whales; approximately 28 people were stranded by Navy sonar. Their autopsies revealed internal bleeding in their hearts and brains.
Noise exposure caused them to panic, changing diving patterns and causing decompression sickness bleeding. Whales often change their breeding and feeding habitats because constant noise alters their migration patterns. They can also change the whale’s call or make it silent.
Research shows that 24 species of cetaceans have adverse reactions to noise. They include sperm whales, pilot whales, beluga whales, killer whales, bottlenose dolphins, humpback whales, porpoises, harbor porpoises and Risso’s dolphins.
What Is Pollution And Where Does It Come From?
Seismic airguns also stranded nine giant squid between 2001 and 2003. These giant squids suffered internal injuries so severe that their internal organs were destroyed. The constant noise also affected the brown shrimp in the tank. The shrimp’s metabolism speeds up due to exposure to noise. This resulted in more than three months of low growth and reproduction rates.
Another marine species that responds to seismic noise is the snow crab. Snow crabs exposed to seismic noise develop internal injuries, ovarian abnormalities, smaller larvae, delayed growth, gill disfigurement, and signs of stress. Some reports suggest that interaction of lobsters with noise can lead to increased appetite. Cod were also affected by seismic noise levels, with an increased appetite for over a month.
Noise pollution seriously affects marine life. Exposure to high noise can cause ear damage in animals within a range of 500 meters to several kilometers. Seismic waves disrupted fishing for haddock, cod, rockfish, blue cod, sand eels and herring. Vessel noise disturbance causes disturbances in the school structure and swimming behavior of bluefin tuna.
Research also shows that goldfish, catfish, bass, bluefin tuna, rockfish, sand eels and cod are among the 21 species of fish affected by noise. Fish of all ages can become sensitive to noise. Research shows that the heartbeats of three-day-old clownfish embryos increase in response to noise.

Noise pollution caused by human activities affects the behavioral patterns of birds. Certain bird species are declining due to noise generated by urban development.
Many bird species have modified their calls to adapt to higher sound levels in the air5. Bird calls are a series of sounds that birds use to communicate. Sound is an important communication tool in bird societies. They use sounds called mating calls to
