Meanwhile, the noise emanated from an industrial area on a working day stood at 85.8dB, while that from a commercial space was 87.2dB. Chhatrapati Shivaji Maharaj Terminus (CSTM) (95.3dB) was the noisiest location across Mumbai during the day.
Following Bombay High Court’s (HC) order, NEERI monitored the noise across 55 locations in Mumbai for 48 hours on both 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).
On Monday, NGO Awaaz Foundation made the report public on their website. Sumaira Abdulali, convener, Awaaz Foundation said that the NEERI report comprehensively measures noise from traffic at numerous spots in Mumbai and validates their findings that traffic is a major contributor to Mumbai’s high noise levels.
