Noise levels on Monday,the eighth day of Navratri,crossed permissible limits at various locations across Mumbai,claim activists.
Activist Sumaira Abdulali recorded noise levels at 10 locations around the city such as Chunabhatti in Sion,Bhandup east,Mulund east and Goregaon. The levels in these areas were between 68 dB and 104.5 dB,she said. The highest noise levels were recorded at Kamal Nagar Society in Bhandup east.
The noise limit in a residential area between 6 am and 10 pm is 55 dB and 45 dB between 10 pm and 6 am.
At many locations,I measured noise levels from the highway,at a distance of around 100 metres from the mandals. The noise levels were above the permissible limit, said Abdulali.
She added that Navyuvak Mitra Mandal in Mulund east,which had obtained special permission but with conditions from the Bombay High Court to organise its Navratri function in a silence zone,violated the order on all counts. The court had asked the mandal to maintain noise limit and not play music beyond 10 pm. However,Abdulali said,noise levels were between 68 dB and 97 dB and the mandal played music beyond 10 pm. Also,the court had asked the mandal to use a distributed sound system instead of loudspeakers,but the mandal did not do so,she said. The mandal is 40 metres from a hospital,she added.
Others,such as Yuva Mitra Mandal in Mulund,also used loudspeakers in silence zones. The noise level at this mandal was 95 dB between 11.15 pm and 11.25 pm,she said. This was in the presence of political leaders and the police, said Abdulali. The noise limit for a silence zone between 10 pm and 6 am is 40 dB.
