Quietest Diwali in Mumbai since 2014: MPCB

Noise levels across the city this Diwali were the lowest in five years but were still above permissible limits for residential areas and silence zones, says the Maharashtra Pollution Control Board’s (MPCB) noise monitoring report.

MPCB officials said there was a 50% decline in use of firecrackers across Mumbai and 30% decline across the state.
