THRISSUR: The sound levels of the just-concluded Thrissur Pooram fireworks display crossed prescribed limits as per the measurements conducted jointly by the state pollution control board (PCB) and Thrissur Engineering College.
Even though the levels are only slightly above the maximum permitted levels, the measurements reveal that the fireworks display this year were more intense than last year.
The highest sound level during the fireworks display this year was 128.2 db, against the maximum permitted level of 125 db, official sources said. The maximum sound level recorded last year was 101 db .
Interestingly, the highest sound levels recorded during this year’s sample fireworks displays of both Thiruvambady (117.1 db) and Paramekkavu (124.2 db) Devaswoms were lower than the maximum permitted levels.
This year’s highest sound level of 128.2 db was recorded during the early morning fireworks display of Thiruvambady side. The noise level was 125.6 db during the early morning fireworks of Paramekkavu side.
The sound level was 126.9 db during fireworks display by the Paramekkavu devaswom after the conclusion of all programmes on the second day of the Pooram. The fireworks display by Thiruvambady side then recorded 124.3 db.
District collector T V Anupama said detailed studies would be conducted to identify the factors that led to the higher noise levels this year, as the quantities of the explosives were lower compared to last year. “I have just received the report on the sound level. We will follow-up it up as soon as the election results are out,’’ she said.
Meanwhile, Archaeological Survey of India (ASI) local unit officials have decided to request their head office to conduct an expert study to assess the impact of the fireworks display on the historically-important mural paintings on the walls of the Vadakkunnathan Temple.
They conceded that the visible impact was limited this year, and only few tiles had fallen down from the roofs of the temple. However, cracks had already developed on the walls adorned with murals during the previous editions of the festival. These cracks would definitely aggravate in the impact of the massive fireworks display held every year as part of Pooram. An expert study was required to assess the extent of damage, a senior official with the ASI said.
