The word noise is derived from a Latin word ‘Nausea’ which means sickness in which one feels to vomit. Noise is the unpleasant and undesirable sound which leads to discomfort to human beings. The intensity of sound is measured in decibels (dB). The faintest sound which can be heard by Human ear is 1 Db. Due to increasing noise around the civilizations; noise pollution has become a matter of concern. Some of its major causes are vehicles, aircraft, industrial machines, loudspeakers, crackers etc. Some other appliances also contribute to noise pollution like television, transistor, radio, etc. when used at high volume.

Classification of Noise Pollution

As per studies, after every ten years, the noise pollution in an area gets doubled. Noise can be classified as the following:

  • Transport Noise
  • Neighbourhood Noise
  • Industrial Noise

Transport Noise

It mainly consists of traffic noise which has increased in recent years with the increase in the number of vehicles. The increase in noise pollution leads to deafening of elderly people, headache, hypertension, etc.

Neighbourhood Noise

The noise from gadgets, household utensils etc. Some of the main sources are musical instruments, transistors, loudspeakers etc.

Industrial Noise

It is the high-intensity sound which is caused by heavy industrial machines. According to many researches, industrial noise pollution damages the hearing ability to around 20%.

Effects of Noise Pollution

There are many effects of noise pollution both on human and animal health some of them are as follows:

  • Skin colour turning pale
  • Contraction of muscles leading to tension and nervous breakdown.
  • The digestive, respiratory and cardiovascular system is affected by ultrasonic sound waves.

Prevention of Noise Pollution

Some noise pollution preventive measures are provided in the points below.

  • Honking in public places like teaching institutes, hospital, etc. should be banned.
  • In commercial, hospital, and industrial buildings adequate soundproof systems should be installed.
  • Musical instruments sound should be controlled to desirable limits.
  • Dense tree cover is useful in noise pollution prevention.
  • Explosives should be not used in forest, mountainous, and mining areas.

According to some of the recent reports it has been proved that the blood vessels are thickened by the excessive sound which is very dangerous for health. There are many ways which are helpful in controlling the noise pollution like we can use source control, receptors control, also proper oiling of machines can decrease the noise coming out of it. The problem of noise needs to be dealt with immediate concern, learn more about the control of noise pollution with the interactive videos at Byju’s The Learning App.
