High decibel level this year

Increasing vehicular population is one of the major causes

 
In three out of four locations where the atmospheric noise level was monitored by the Karnataka State Pollution Control Board (KSPCB) on October 17, 18 and 19, the variation in noise levels ranged between 2 and 32 decibel (see box) over the previous year. Noise levels were monitored between 5 pm and 11 pm on the above stated days.

Locations monitored fell under different categories namely, AECS Layout (residential area), Cubbonpet (commercial area) and Indiranagar ESI Hospital (sensitive area), said Member Secretary KSPCB, M S Goudar. Vijayanagar Club (residential) was the only part that showed a decrease in decibel level when compared to last year’s Deepavali, he added.

“It is not merely the crackers but annual increase in vehicular population and subsequent noise created by them have contributed to high decibel levels,” he said. Maximum noise this Deepavali, 114 dB was registered for a short period at Cubbonpet. This year revealed the maximum decibel level when compared to the noise levels in the last three years. There has been a huge increase in decibel levels even on regular days this year, when compared to previous year, due to increasing vehicular population, he pointed out. Increase ranged between 7% and 22% at these areas over the previous three years (see box)
An order from the Centre’s Petroleum and Explosives Safety Organisation prohibits the manufacture, sale or use of firecrackers generating noise level exceeding 125 dB. This is in line with a Supreme Court directive in this connection.

“The saving grace is that the human ear can put up with this increase in noise level. Moreover, it is for a short duration only,” the Member Secretary said.
