Measures to Reduce Noise Pollution
Excessive noise that may harm human health is called noise pollution. There are laws to reduce noise pollution but due to lack of awareness, people do not care about them. The need is that people should try to understand the importance of these laws and should follow them strictly. Government also tries to create awareness about noise pollution in public through media. Bus stands, airports and factories need to be shifted away from residential areas. Use of horns near hospitals, educational institutions and libraries should strictly be prohibited (Figure 8.8).

Proper silencers should be used in the vehicles. The volumes of TVs or tape record[1]ers should be kept low. The use of loud speakers at high volume has been prohibited. Trees should be grown wherever possible because they help to reduce noise and other types of pollution.
