Even as Diwali this year was a ‘sombre’ affair in SAS Nagar, still the residential areas of SAS Nagar were noisier as compared to the Diwali day last year.
The commercial and areas around hospitals were a bit calmer than last year even though the level of noise remained well beyond the permissible level.
The effect of call for ‘Black Diwali’ given by Sant Samaj this year in protest against the incidents of sacrilege of ‘birs’ of Guru Granth Sahib at various places in Punjab was evident in the commercial areas that wore a deserted look and the noise pollution level registered a dip as compared to last year.
According to the data available with the Punjab Pollution Control Board (PPCB), the level of noise exceeded the permissible limits in residential as well commercial areas.
The PPCB had divided the town into three zones — sensitive areas like hospitals, commercial and residential — for the purpose of ambient noise monitoring.
A seven-hour monitoring was conducted starting at 5pm on Wednesday till midnight. The noise levels were recorded every hour.
The level of noise pollution near the Fortis Hospital was recorded at an average of 66.9 dB against the permissible limit of 40dB.
In the residential area of Phase 7, too, the average level of noise pollution was high and recorded at an average of 75.7 dB against the permissible limits of 55dB.
However, in the commercial areas of Phase 7, the average noise pollution was recorded at 57.2 dB which was lower than the permissible limit of 65 dB.
