Most of us are accustomed to the sounds we hear every day. However, when the sound of the television keeps you from sleeping all night or the traffic starts giving you a headache, it transcends the boundaries of mere noise and qualifies as noise pollution.

It is also a very effective alarm system. Noise can be defined as an unpleasant and unwanted sound. Exposure to loud noise is indeed annoying and harmful too. Its effects are more directly on the receiver i.

Noise Pollution: Definition, Sources and Effects of Noise Pollution

Do Latex Mattresses Sag? March 01, Latex Mattress Buying Guide February 22, Posted on Sep 19, by Amber Merton. Although sound is something that is essential within our daily lives, noise is not. Sounds that cause discomfort to the ears, that produce unpleasant effects, or are unwanted, are considered to be noise. Noise pollution generally interferes with normal activities, for example, conversing or sleeping.

This type of pollution can also diminish or disrupt quality of life. Not all noise is considered to be pollution. These mammals, who use their ears more than their eyes, make calls that travel distances of 20 miles and more.

They need to do this to communicate, in much the same way as humans need to. It also helps prevent them from becoming lost during migration. Sound and noise is measured in decibels dB , and according to statistics from the Center for Hearing and Communication, continued exposure to noise levels measuring more than 85 dBA adjusted decibels will cause hearing loss over time. Both the length of exposure to the sound, and the volume dBA will tell you how harmful the noise is.

What this also means is that with these adjusted decibels, the values of low frequency sounds are reduced as the human ear is less sensitive at this frequency. This is different to regular unweighted decibels, where no correction is made for audio frequency.

This list will help illustrate the range of environmental noise levels that affect everyone in society today. According to statistics from the Dangerous Decibels, prolonged exposure to noise over the threshold of 85 decibels can become an issue, especially when the exposure time to the sound increases. With these figures in mind, it is important to note that the effects of noise pollution on humans are best understood by examining the different types of noise an individual is exposed to daily.

Other types of man made noise pollution are recreational in nature. Dangerous Decibels states that at maximum volume, personal music players can exceed decibels, which can cause irreversible damage to the hearing of people who listen for only 15 minutes a day. The effects of noise pollution on the health of humans can be vast — including having mental, behavioral, and physical effects.

For usually nervous individuals, noise can make them feel even more nervous, angry, and irritable. Looking beyond these symptoms, the other long-term effects of noise pollution are often even worse. Information from Conserve Energy Future CEF indicates that noise pollution is connected to sleeping disorders, elevated blood pressure, stress, and cardiovascular problems. Furthermore, the fatigue that living with noise pollution presents to an individual must not be downplayed. When an individual is constantly exposed to chronic levels of noise, he could easily begin to suffer from a loss of hearing.

There are various ways in which this chronic exposure can occur; these include:. For anyone worried about the potential effects of noise pollution, it is a good idea to keep the noise within the controllable home environment to a minimum.

Utilizing home improvement methods such as soundproofing walls, and installing double glazing are also useful for in-home noise pollution. It is also good practice to check the noise ratings of all tools, and appliances you introduce into the home, choosing only the quietest products where possible. However, in the case of neighbors with barking dogs and such, it is always possible to negotiate and to come to some form of agreement in terms of handling the problem.

Life can be incredibly difficult for people who have to live with the crippling fallout of noise pollution on a daily or regular basis, and this is why the issue is something that needs to be looked at in detail, and addressed as soon as possible.

Environmental Noise Levels Measured in dBA This list will help illustrate the range of environmental noise levels that affect everyone in society today. Types of Noise There are various different types of noise pollution, including: Man Made Noise — including traffic, subway noise, airports, constructions sites, transport, and so on.

In fact, figures from Dangerous Decibels indicate that the sound of an idling bulldozer can reach as high as 85 decibels, and people who work closely with the machines can sustain irreversible damage to their hearing within just one day.

Environmental Noise — including animal sounds, barking dogs, and loud thunderstorms. It might not seem like it, but according to Dangerous Decibels, the sound of thunder during a particularly bad storm can hit over decibels.

The Effects of Noise Pollution on Humans The effects of noise pollution on the health of humans can be vast — including having mental, behavioral, and physical effects. Chronic Noise Exposure When an individual is constantly exposed to chronic levels of noise, he could easily begin to suffer from a loss of hearing. There are various ways in which this chronic exposure can occur; these include: Living in the city — Background noise is just something that city-dwellers live with without noticing.

Work-related noise — According to OSHA, noise pollution-related hearing loss has been a huge occupational health problem in the U. There have been many steps taken within various affected industries to protect their employees from hearing loss via the introduction of protective equipment such as noise-reduction earplugs.

Protection from Noise Pollution For anyone worried about the potential effects of noise pollution, it is a good idea to keep the noise within the controllable home environment to a minimum.

What is Noise Pollution?

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.

Noise Pollution: Definition, Sources and Effects of Noise Pollution

Noise pollution has become a major environmental problem leading to nuisances and health issues. This paper aims to study and analyse the noise pollution levels in major areas in Ota metropolis. A probability model which is capable of predicting the noise pollution level is also determined.

Noise pollution

Noise health effects are the physical and psychological health consequences of regular exposure to consistent elevated sound levels.

The main air pollutants are represented by gases forms, particles in suspension, different ionizing radiation and noise. The particulate forms are: PM10 and PM2. Atmospheric pollutants have a negative effect on the plants; they can have direct toxic effects, or indirectly by changing soil pH followed by solubilization of toxic salts of metals like aluminum. The particulate matters have a negative mechanical effect.

Air pollution and excessive noise harm our health and our environment. Air pollution mainly stems from industry, transport, energy production and agriculture. The Environmental Noise Directive helps to identify noise levels in the EU and to take the necessary measures to reduce them to acceptable levels. Separate legislation regulates air and noise pollution from specific sources. Air pollution can cause cardiovascular and respiratory diseases as well as cancer, and is the leading environmental cause of premature death in the EU. Certain substances, such as arsenic, cadmium, nickel and polycyclic aromatic hydrocarbons, are human genotoxic carcinogens, and there is no identifiable threshold below which they do not pose a risk. Air pollution also negatively impacts on the quality of water and soil and damages ecosystems through eutrophication excess nitrogen pollution and acid rain.

  • It may occur due to continuous exposure to noise level of more than 90 dB. It may be temporary or permanent. Explosions or other high intensity sounds can also cause immediate deafness by rupturing the ear drums or damaging the cochlea. Many time hearing loss is attributed to occupation.
