Railways and road transport are the topmost contributors to noise in the city, according to a first-of-its-kind noise-mapping by National Environmental Engineering Research Institute (NEERI).

At 89 decibels (dB), the average noise level from railways on working days was the highest, followed by major roads and national highways at 88.7dB and 85dB, respectively, according to the findings of the study. The noise emanated from an industrial area on a working day stood at 85.8dB, while that from a commercial space was 87.2dB.

Based on a Bombay high court (HC) order, NEERI monitored the noise from 55 locations in Mumbai for 48 hours on working and non-working days. The locations were divided into nine categories – railways (7 locations), national highway (4), expressway (1), major and minor roads (10), industrial sites (10), commercial (8), residential (10), and silence (5). The study found the noise at commercial, residential and silence zones were all above the permissible limits (see box).

The report was made public by NGO Awaaz Foundation’s website on Monday.

Chhatrapati Shivaji Terminus (CST) (95.3dB) was the noisiest location across Mumbai during the day.

Anti-noise campaigners, however, said transport cannot be termed a major contributor, as other sources have not been studied in detail. “The NEERI report comprehensively measures noise from traffic at numerous spots in Mumbai and validates our findings that traffic is a major contributor to Mumbai’s high noise levels. However, other noise sources are not specified and it is unclear how this report will be integrated into the city’s development plan,” said Sumaira Abdulali, convener, Awaaz Foundation.

NEERI officials said they would not like to comment on the report as the matter was sub-judice. “We have already submitted the report,” said NEERI director Dr Rakesh Kumar.
