Noise pollution in the Ranchi zone of silence increased 66% on Diwali on Saturday after a massive violation of the two-hour window granted by the Jharkhand State Pollution Control Board (JSPCB) for setting off firecrackers, according to the data released by the board on Sunday.

The same area recorded a 37% increase in noise pollution against the boundary during the two-hour window.

By order of the National Green Court (NGT), JSPCB issued an order on November 12 granting a two-hour window, from 8 pm to 10 pm, to set off firecrackers on Diwali.

The board measured the status of noise pollution in four places: Jharkhand High Court (quiet zone), Albert Ekka Chowk (commercial zone), Kutchery Chowk (commercial zone) and Ashok Nagar (residential area), on Saturday from 6 p.m. to 12 pm.

The High Court of Jharkhand, the city’s quiet zone, recorded an average noise pollution of 67.83 decibels (dB) between 6 p.m. and 12 p.m. on Diwali, a slight drop compared to the measurement prior to Diwali The area registered 70.28 dB on November 9.

The silence zone registered 68.55 dB during the window hour, from 20:00 to 22:00 hours against the permissible limit of 50 dB, while the same zone registered 66.5 dB during the hours after the window, from 22:00 to 12:00, against the limit of 40 dB.

The allowed limits for the quiet zone are 50 dB during the day (6 am to 10 pm) and 40 dB during the night (10 pm to 6 am).

Similarly, Ashok Nagar, the posh town in the city, recorded an average decibel of 71.28 for six hours against the limit of 55 dB in the day and 45 dB at night. The area recorded 74.45 decibels during the assigned hours against the 55 dB limit and 71.6 dB after 10 pm to 12 pm, against the 45 dB allowable limit.

The residential area had registered an average of 57.85 dB in six hours during the pre-Diwali measurement.

The Albert Ekka Chowk shopping areas recorded an average noise pollution of 78.41 dB and Kutchery Chowk of 74.31 dB over the six-hour period. The permitted limits for commercial areas are 65 dB during the day and 55 dB at night.

Shopping areas recorded 70.9 dB and 72.36 dB respectively during the pre-Diwali assessment on November 9.

Albert Ekka Chowk recorded 80.9 dB during the assigned hours and 73.75 during the hours after the window. Similarly, Kutchery Chowk recorded 74.31 dB during window hours and 71.3 dB during window hours on Diwali night.

JSPCB analyst RN Kashyap said: “The increase in noise pollution during the hours after the window appears to be due to the ignorance of Diwali revelers. It appears that the order of the two-hour window had not reached many residents. “

“In some places like Albert Ekka Chowk, the increased noise level is appearing due to other factors, such as the speakers and the sound of the vehicles,” he said.
