Noise levels on the last day of immersion on Sunday exceeded the permissible limit at various spots across the city.
Noise levels measured by Awaaz Foundation, a non-governmental organisation, showed that areas such as Mahim, Matunga, Santacruz, Worli and Parel were noisier than last year, with firecrackers and DJs playing music from atop trucks that accompanied the idols.
The noise level opposite Asha Parekh hospital in Santacruz was 98dB as compared to last year’s 91dB. The hospital falls within a silence zone, which comprises areas within 100 metres of courts, educational institutions, hospitals and places of worship.Noise pollution rules specify that the permissible noise level during the day is 50dB in silence zones and 55dB in residential areas. Noise levels near Siddhivinayak temple at Prabhadevi, another silence zone, touched 101dB at 9.49pm owing to loud music. At Worli naka, it rose up to 100dB at 10pm against last year’s 86.8dB.
“Though noise levels during the entire festive period was much lower than last year, the level on the last day of immersion was terrible in certain areas,” said Sumaira Abdulali, convener of the Foundation.
Abdulali said that compared to 2010, almost all big processions had loudspeakers mounted on trucks. “It seemed like a discotheque along the immersions routes,” she said.
The NGO said areas such as Juhu, Bandra and Girgaum Chowpatty were less noisy. From 10.50pm onwards, the noise level at Girgaum Chowpatty oscillated between 77dB and 100dB compared to 2010 when it was between 97dB and 102.9dB.
The noise level in residential areas also exceeded the permissible limit. While it measured 98 dB at Sena Bhavan, Dadar, it touched 78dB at Mehboob Studio, Bandra.
The state had extended the 10pm deadline to midnight, and the noise level skyrocketed along the immersion routes. From 11pm to midnight, the noise level on Lamington Road was between 100dB and 105dB.
