Effects of noise pollution

Effects of noise pollution can be harmful for human.
Noise is unwanted sound.Noise from industry, traffic, homes and recreation can cause annoyance, disturb sleep and affect health.Noise is an important environmental pollutant like noxious gases that befoul our
air, water and soil.The human ear is a very sensitive instrument. If the hearing mechanisms are damaged in any way either by excessive noise levels or by diseases which affect the brain, the auditory nerve or the auditory ossicles, then hearing will be impaired.Exposure to continuous noise of 85–90 dBA, particularly over a lifetime in industrial settings, can lead to a progressive loss of hearing, with an increase in the threshold of hearing sensitivity.Noise exposure during sleep may increase blood pressure, heart rate and finger pulse amplitude as well as body movements. There may also be after-effects during the day following disturbed sleep; perceived sleep quality, mood and performance in terms of reaction time all decreased following sleep disturbed by road traffic noise.

Sources of noise pollution: traffic, concerts, airplanes, industrial machinery, construction or demolition …
Effects of noise pollution: hearing loss in humans and in animals.

Noise has become a very important “stress factor” in the environment of man. The term “noise pollution” has been recently used to signify
the hazard of sounds which are consequenceof modern day development, leading to health hazards of different type.There are many vulnerable groups of people who are most affected by noise pollution such as the young, elderly, and the hospitalized.

What can you do?
Try to use acoustical tile ceilings, wall coverings, and bookshelves to absorb sound.Close windows and doors to shut out noise from road and plane traffic.Place noisy activities next to each other, away from
areas needing quiet for concentration on quiet, learning activities.
Making a change in design and operation of machines, vibration control, sound proof cabins and sound-absorbing materials can reduce it.
Trees and shrubs may be planted in front of building to provide some absorption for the sound.
People can be educated through radio, TV, newsreels in cinema halls about noise pollution. In the family, elders can teach children to keep the radio volume low, low voice talking not to horn unnecessarily on the roads, avoid quarreling amongst each other and so on.
