Delhi's Diwali Decibel Distress: Noise Pollution Soars Despite Restrictions

Delhi experienced elevated noise pollution levels during Diwali, with a significant number of areas breaching permissible decibel limits. Despite restrictions, real-time data indicated an increase in noise compared to previous years. Efforts to manage sound pollution remain vital alongside measures for air pollution control.

This year's Diwali in Delhi proved to be one of the noisiest, with most neighborhoods exceeding permissible noise limits despite existing restrictions. An analysis of real-time data from the Delhi Pollution Control Committee (DPCC) showed 23 of 26 noise monitoring stations experiencing sound levels above the legal limits, a rise from previous years.

Among commercial regions, Karol Bagh stood out, registering a peak noise level of 93.5 dB(A) around 11 pm on Diwali night, slightly lower than last year's 94.5 dB(A). Despite a minor drop, the consistent noise levels throughout the following day kept the region well above the night-time limit of 55 dB(A).

The Central Pollution Control Board (CPCB) classifies Delhi's noise zones into silence, residential, commercial, and industrial categories. These have maximum permissible limits from 40 dB(A) to 70 dB(A) at night. Yet, many areas, including silence zones such as Sri Aurobindo Marg, reported noise peaking near double the allowed levels, highlighting the pressing need for effective noise pollution control measures.
