Question

What are the control methods of noise pollution ?

Answer 1

The increase in the volume or noise level more than the normal or permitted noise level is called noise pollution which can be unsafe for human health and other organisms in the environment .

Complete answer:

The increase in the level of noise has become unhealthy causing serious health issues and imbalance in the environment which shows that high volume noises are abnormal for everyone .
The high volume of noise causes psychological and physiological disorders in humans such as insomnia or sleeplessness , increased heartbeat that is tachycardia and altered breathing pattern .
The cause of noise pollution is many electrical appliances used in homes such as coolers , mixers or grinders , televisions, music players etc. Even the equipment like compressors , exhaust fans , generators create large amounts of noise .
These appliances due to their effect on the environment fall in the category of a pollutant and disturb the natural rhythm of life . Noise pollution is observed in bigger metropolitan cities more often .
The noise generated by take off of a jet plane or rocket can create 150 dB of sound which can damage the ear drums causing hearing disability . Not only this , even low sound level exposure can permanently damage hearing abilities of humans .
Due to all these harmful effects of high levels of noise , noise was considered as a pollutant and the government of India had to take serious measures to control the level of noise in cities .
Noise was included as an air pollutant and hence in the year 1981 , the Air (Prevention and Control of Pollution ) Act came into force , but it was amended 6 years later that is in the year 1987 .
After the implementation of this act , stringent following of laws was laid down to reduce the noise pollution like delimitation of horn – free zones around hospitals and schools , timings after which loudspeakers cannot be played and permissible sound – level of crackers and loud speakers .
Humans can experience serious health issues like sleeplessness , headaches , migraine due to noise pollution and even experience fatigue and tiredness due to lack of sleep . Such people are given sleep producing pills to treat them .

Note: Not only humans but even other animals are affected by noise pollution such as pets become aggressive or even scared of high noise levels . Therefore crackers should not be burst when pets are around .
