Sound pollution in Ranchi’s silent zone rose 54.22 percent above the permissible limit for Diwali, an official said on Tuesday.
However, when compared to the pre-Diwali level on October 18, a week before the festival, there was a 6.34 percent increase in noise on Monday, the official stated.
The Jharkhand State Pollution Control Board (JSPCB) has given a two-hour window – 8:00 PM to 10:00 PM – for bursting firecrackers on Diwali.
The board monitored sound pollution levels in four areas of the city — Jharkhand High Court (silent area), Albert Ekka Chowk (commercial area), Kutchery Chowk (commercial area) and Ashok Nagar (residential area) — for six hours from 6 pm on Monday. .
At Albert Ekka Chowk and Kutchery Chowk, the sound pollution levels were 2.33% and 1.96% higher than pre-Diwali figures respectively, according to the JSPCB data.
Similarly, Ashok Nagar registered a 3.06% increase over the pre-Diwali figures, according to data.
”Ranchi’s silent zone recorded 69.4 dB between 6pm and 12 midnight during Diwali against the average permissible limit of 45dB. Ashok Nagar, a residential area, recorded 55.46 dB on average during the period.
”The commercial areas of Albert Ekka Chowk and Kutchery Chowk recorded 75.33dB and 72.76 db respectively on average,” JSPCB analyst Ramanand Anjan said.
A ban on firecrackers that produce noise above 125 decibels (dB) has helped curb sound pollution to an extent in the state capital, Anjan told PTI.
”If we compare Diwali and pre-Diwali noise pollution, we see that there was no significant difference. It seems that people are becoming aware of the ill effects of bursting firecrackers. Banning the sale of firecrackers that emit sound above 125 decibels (dB) may have helped us control noise pollution,” added Anjan.
