Do you know which is the loudest city in India?

Noise pollution is not a new thing in the lives of people dwelling in metro cities across India. Now a study of Central Pollution Control Board has revealed that Chennai is the noisiest city in India. The capital of Tamil Nadu is followed closely by Hyderabad and Mumbai.

A number of locations in the city of Chennai have been violating the noise levels. The study was bifurcated in several categories across the city.

Anna Nagar was placed under the silence zone. T Nagar, Perambur, Washermanpet and Pallikarnai were placed under the commercial zone. Guindy was kept under the industrial and Triplicane, Velachery and Sowcarpet were studied from the residential zones.

Most of these places violated the usual permissible levels - silence zone (50 dB), residential (55 dB), commercial (65 dB) and industrial (75 dB). What is more surprising is that eight out of these nine marked places, the noise pollution seemed to be almost double the normal level.

CPCB stated that vehicles and industrial activities are the reasons for this noise pollution.
