Chennai: Chennai is the fifth most noisiest metro city in India as per a report by Central Pollution Control Board (CPCB) and its commercial, residential and “silence” zones are actually noisier than its industrial zones.
The CPCB gathered data from 35 noise monitoring systems installed by it in nine metro cities, including Chennai, for the period 2011-14 and compiled it to get an idea of noise pollution problem in its report ‘Status of ambient noise levels in India’.
Analysing the compiled data for four years, it was found by CPCB that Chennai stood fifth in violations of CPCB-set noise level standards after Mumbai, Lucknow, Hyderabad and New Delhi. In the same period, Bengaluru and Kolkata have observed least number of violations.
In Chennai, noise monitoring systems by CPCB are located at two commercial zones, T Nagar and Perambur, one silent zone, eye hospital, one industrial zone, Guindy and one residential zone, Triplicane.
T Nagar, Triplicane and Perambur performed the worst as noise recorded exceeded CPCB prescribed limits for every single observation. In eye hospital, a silence zone, the noise levels recorded always reached limits of commercial zone which is 65dB in the morning and 55dB at night.
