Diwali this year in the city has turned out to be less noisy than that of the preceding year. If the noise levels recorded by the Andhra Pradesh Pollution Control Board (APPCB) are to go by the festival of lights has been a tad muted affair.

Initial data collated by the PCB on the festival day when the noise levels usually peak due to bursting of crackers show a marginal rise when compared to the normal days.

In residential areas, noise level at Pragatinagar rose to 67 decibel (dB) on November 13 against a normal observation of 57 decibels while the same at Jubilee Hills went up to 53 dB against daily normal of 49 dB.

In commercial areas, rise in noise levels was by three dB at Abids followed by one dB rise found at Paradise and Punjagutta. Similarly, the rise in noise levels at industrial areas was to the effect of eight dB at Uppal and in the silence zones, it went up by one dB at the Nehru Zoological Park observation point.

“Overall, the rise has been marginal compared to the daily normal recording and also when seen against last year recoding,” said an official.

The final averages of noise levels were being worked out and the PCB was also in the process of tabulating the rise in dust levels too during the season.

The prescribed noise levels for different zones include 55 dB for commercial zone, 45 dB for residential zone, 70 dB for industrial and 40 dB for silence zones. The zone wise noise level averages on last year Diwali day were 83 dB in commercial, 74 dB in industrial, 65 dB in silence and 88 dB in the residential.
