NOISE POLLUTION

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 systems, motor vehicles, aircraft, and trains . Outdoor noise is summarized by the word environmental 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.

Indoor 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.

EFFECTS OF NOISE POLLUTION ON HUMANS Generally, problems caused by noise pollution include stress related illnesses, speech interference, hearing loss, sleep disruption, and lost productivity. Most importantly, there are three major effects we can look at:

HearingThe immediate and acute effect of noise pollution to a person, over a period of time, is impairment of hearing. Prolonged exposure to impulsive noise to a person will damage their eardrum, which mayresult in a permanent hearing impairment.

EFFECTS OF NOISE POLLUTION ON MARINE ANIMALSMarine AnimalsMarine scientists are concerned about excessive noise used by oil drills, submarines and other vessels on and inside the ocean. Many marine animals, especially whales, use hearing to find food, communicate, defend and survive in the ocean. Excessive noises are causing a lot of injuries and deaths to whales. For example, the effect of a navy submarine’s sonar can be felt 300 miles away from the source. 

(SONAR is the use of sound by submarines and other fishing vessels to deterring the depth of water, the closeness of an object, or detect movement of other objects in the water.

HOW TO REDUCE NOISE POLLUTION ? Noise pollution prevention and control tips

1 ] Below are a few things people and governments can do to make our communities and living laces quieter:

2]Construction of soundproof rooms for noisy machines in industrial and manufacturing installations must be encouraged. This is also important for residential building—noisy machines should be installed far from sleeping and living rooms, like in a basement or garage.

3] Use of horns with jarring sounds, motorbikes with damaged exhaust pipes, noisy trucks to be banned.

4] Noise producing industries, airports, bus and transport terminals and railway stations to sighted far from where living places.

5] Community law enforcers should check the misuse of loudspeakers, worshipers, outdoor parties and discos, as well as public announcements systems.

6] Community laws must silence zones near schools / colleges, hospitals etc.

7] Vegetation (trees) along roads and in residential areas is a good way to reduce noise pollution as they absorb sound.
