How to control noise pollution?

There are many methods which help to control the noise pollution. The source of noise must be reduced. The path of transmission of sound must be stopped and the receiver of noise must be safe guarded. The amount of traffic must be reduced near the residential homes, educational institutes and hospitals. The machinery must be redesigned and the vehicles must be properly maintained. The acoustical furnishing must be done so that the sound can be absorbed. The voice must not be passed directly to the receiver and must be diverted upwards instead of downwards as in case of ear splitting jet exhaust noise. The industries must be built away from the residential areas and the legal laws must be established and observed to protect the humans from noise pollution. A general awareness programme to educate the people must be done. It is basically a public nuisance which affects the human beings in almost all aspects.
