The noise pollution level crossed the permissible decibel count in most places of Ranchi on Diwali though it was less compared to last year, Jharkhand State Pollution Control Board officials said on Thursday.
The pollution board had installed machines to calculate sound levels at six places in the state capital from 6pm to midnight on Wednesday and the noise pollution was found to be higher than the permissible level in all the areas, officials said. The maximum noise pollution was recorded from 6pm to 9pm.
The machines were installed at Albert Ekka Chowk, MECON, high court, Sujata Chowk, Van Bhawan and Raj Bhawan.
The permissible decibel count in silence zones is 40 dB during nights and 50 dB during days. For commercial areas the permissible count is 65 dB during days and 55 dB during nights and for residential areas, it’s 55 dB and 45 dB.
The average noise calculated by the machines in the city was 72.5 dB this year, down from last year’s 82.83 dB, said JSPCB member secretary Sanjay Kumar Suman.
“The noise pollution was well above the permissible limit,” said Suman.
The state’s pollution department and green activists are concerned over the environmental hazards of bursting crackers. Animal rights activists also oppose bursting of crackers during the festival of lights as it is believed to have adverse effects on cattle and animals.
The fall in the decibel count this year is being seen as a positive sign by green crusaders and animal rights activists.
“The fall in decibel count is a good indication, but the city is still far from celebrating a green Diwali,” said Sunil Kumar Singh, a green activist based in Ranchi. “The day is still far when every person would realise the adverse effects of bursting crackers.”
Campaigns were run across the country by environmental organisations for ban on high-decibel crackers. “Many pet parents in Ranchi did not burst crackers this Diwali considering the trauma it brings to animals,” said veterinarian Suranjan Sarkar.
