After more than three years of mulling over how to record noise levels in Mumbai, BMC has finally ordered a noise mapping survey. As a part of the survey, noise levels across 1,200 locations and their patterns will be recorded.
This will help the Brihanmumbai Municipal Corporation (BMC) narrow down on areas with high noise levels, and which may need sound barriers.
The proposal, estimated to be worth Rs 61 lakh, will be tabled before the standing committee meeting for approval on Wednesday. If passed, it is expected to be completed in 12 months (excluding monsoon).
The move comes after several concerns were raised in the past regarding increasing level of noise pollution in the city.
The civic body does records noise levels in different parts of the city and releases a yearly environment status report (ESR). However, because of lack of comprehensive data, it has failed to take substantial steps to curtail the increasing noise pollution.
In 2012’s ESR, the BMC had recorded way beyond the permissible limit in all residential, silence, traffic zones and areas around the airport.
As part of the noise mapping, the consultant will study around 50 places spread across 24 wards. The consultant will be required to take readings of a place at different hours as well as on weekends.
According to the data collected, the consultant will then have to propose ideas and technologies to bring down noise levels.
The idea to map the city’s noise level and survey areas to install barriers was first floated in 2011, after a high-level delegation had visited Italy.
Soon after, an Italy-based company was appointed to map five noise-sensitive spots, following which the civic body was to put up sound barriers. However, the plan is still to be executed.
“It is a positive step by the civic body to control the menace. The BMC lacks comprehensive data to implement ways to mitigate noise pollution. The data will lead to better planning,” said Sumaira Abdulali, convener, Awaaz foundation.
