"HOW TO PREVENT NOISE POLLUTION"



PREVENTING NOISE POLLUTION:

Spend time away from noise. Sometimes it's simply impossible to truly get away from the noise. If you live on a busy street with lots of traffic, you know there's never really a respite from traffic sounds, sirens and honking horns. Getting away from it all is a good way to restore your emotional balance. Go to a quiet spot that's as free of sound as possible. Stay there and enjoy the silence for a few hours, until you feel renewed and ready to reenter the noise of daily life.
  • See if you can go for a walk in a quiet natural spot away from busy roads.
  • If you can't make it to a quiet outdoor space, try sitting in a library for a few hours. The librarians will make sure it stays nice and quiet.
  • Churches and cemeteries are also good places to find some peace and quiet.

  • When you're feeling overwhelmed, sit very still, close your eyes and focus on taking deep, even breaths. Do 10 breaths and try to let your worries go and ignore the noise around you. No matter where you are, whether it's on a noisy subway car or in your own kitchen, you can try this technique to calm yourself down.

Earplugs are a cheap drugstore purchase that buys you hours of sleep, once you get used to falling asleep with them in your ears. Noise-canceling headphones are a bit more expensive, but if getting peace and quiet is at the top of your priority list, they're probably worth the splurge.


Install noise-reducing insulation and glass. This is by far the most expensive method, but if nothing else is working for you, and you are serious about the peace and quiet, this is a most effective way to stop noise from getting in your home.









"HARMFUL EFFECTS OF NOISE POLLUTION"


HARMFUL EFFECTS OF NOISE POLLUTION:

  • It interferes with speech. In the presence of noise we may not able to follow, what the other person is saying.
  • Noise leads to emotional and behavioral stress. A person may feel disturbed in the presence of loud noise such as produced by heating of drums.
  • Noise may permanently damage hearing. A sudden loud noise can cause severe damage to the eardrum.
  • Noise increases the chances of occurrence of diseases such as headache, blood pressure, heart failure, etc.
  • Noise leads to increased heart beat, constriction of blood vessels and dilation of pupil.
  • Noise is a problem especially for patients who need rest.
  • Noise may cause damage to liver, brain and heart.

What is Noise Pollution?

Noise pollution or noise disturbance is the disturbing or excessive noise that may harm the activity or balance of human or animal life. The source of most outdoor noise worldwide is mainly caused by machines and transportation systemsmotor vehiclesaircraft, and trains.Outdoor noise is summarized by the wordenvironmental noise. Poor urban planning may give rise to noise pollution, since side-by-side industrial and residential buildings can result in noise pollution in the residential areas. Documented problems associated with urban noise go back as far as Ancient Rome.
Outdoor noise can be caused by machines, building activities, and music performances, especially in some workplaces. Noise-induced hearing loss can be caused by outside (e.g. trains) or inside (e.g. music) noise.
High noise levels can contribute to cardiovascular effects in humans and an increased incidence of coronary artery disease. In animals, noise can increase the risk of death by altering predator or prey detection and avoidance, interfere with reproduction and navigation, and contribute to permanent hearing loss.


Noise pollution is undesired sound that is disruptive or dangerous and can cause harm to life, nature, and property. It is often said that noise differs from other forms of pollution in that, unlike atmospheric pollutants for example, once abated, noise leaves no residual accumulation in the environment or the human body. Noise does leave behind its effects, however, and these can deteriorate after continued exposure to harmful sounds. So it is not true, strictly speaking, that “noise … leaves no visible evidence” (Lai 1996, p. 389).
The hazardous effects of noise depend on its intensity (loudness in decibels), duration, and frequency (high or low). High and low pitch is more damaging than middle frequencies, andwhite noise covering the entire frequency spectrum is less harmful than noise of a specific pitch. Noise may be ambient (constantly present in the background) or peak (shorter, louder sounds).
