A comparison of Maharashtra Pollution Control Board (MPCB) readings from 10 monitoring stations on November 1 and 8 showed the city’s average night-time noise level rising by 8.4 dB, from 60.5 dB to 68.9 dB. Daytime noise also increased, from 69 dB to 72.3 dB, but the sharpest spike was recorded after dark, when noise levels are expected to be lower. As per MPCB data, night-time noise increased at nine of the 10 monitoring stations, indicating that a quieter Diwali remained out of reach for much of the city.
The findings also raise questions about the enforcement of restrictions on late-night firecracker bursting.
