BANGALORE: After the successful launch of the first phase of National Ambient Noise Monitoring Programme (NANMP) in the city, five more sensitive and prime noise zones will have noise monitoring systems in the second phase. The proposed zones are Victoria Hospital, Indira Gandhi Institute of Child Health, City railway station, Whitefield and Domlur.The first phase of the programme was launched in the beginning of this year and the Minister of Environment Jairam Ramesh was keen on the launch of second phase by April. Due to the delay in selection of land and adequate space, the launch witnessed delay.According to a senior officer at Karnataka State Pollution Control Board (KSPCB), no one wanted to provide space for installing these stations, which led to delay. During the first phase, noise monitoring systems were installed on Church Street, Sanegoravanahalli (Basaveshwaranagar) BTM layout, Peenya Industrial Area and Kaadubeesanahall. Bangalore and other six city including Hyderabad, Mumbai, Kolkatta, Lucknow, Chennai and Delhi have been chosen to have these ambient noise monitoring sytems.The network will provide round the clock data, which will further help in assessing the noise level during a particular period and time. A S Sadashivaiah, chairman, KSPCB, told Express that the network will help in continuous monitoring of noise levels. The data generated will be shared with the Central Pollution Control Board (CPCB). Further, it can also be used to ensure smooth flow of traffic.KSPCB says that in any industrial area in the city, the noise level should not exceed 75 decibel during the day and 70 decibel at night. In commercial areas, it should be 65 decibel during day and 55 in the night. In residential areas 55 should be the limit during day and 45 in the night. In silent zones like hospitals and schools, it is 50 in day and 40 in night.
