Mumbai celebrated its quietest Diwali in 15 years according to records maintained by Awaaz Foundation. The city generated a decibel level of 112.3, down from 117.8 dB in 2017 and far lower than 145dB in 2010 when most firecrackers exceeded permissible levels.
Sumaira Abdulali of the NGO Awaaz Foundation said the lower decibels may be a result of greater awareness among people about curbing noise pollution apart from a fall in use of firecrackers over a period of time.
“This Diwali has been the quietest in 15 years since Awaaz Foundation began recording decibel levels in the city. Till about 2010, 100 per cent firecrackers exceeded the maximum permissible decibel levels. In some case, they were as high as 145dB,” she said.
Abdulali said the bursting of firecrackers continued till 10:45 pm across the metropolis, though the intensity waned after 10:15 pm on Sunday.
