To monitor noise pollution, the Bihar State Pollution Control Board will install sound level meters in nine cities across the State, an instrument used to assess noise and sound levels by measuring sound pressure.
“Having five such meters at various locations, the Pollution Control Board has planned to expand this network to cover more cities in the state that has divisional headquarters or cities with municipal corporations”, said BSPCB Scientist SN Jaiswal.
Reasons for noise pollution in the city are three-wheelers, constant honking by motorists, generator set, and construction activities, said BSPCB chairman Ashok Kumar Ghosh.
Plants can contribute to reduce the noise pollution, as fleshy leaves, stems, branches, and wood can absorb sound.
Residents of the neighborhood in Patna also complained about the constant noise due to some manufacturing activity by some traders and they refused to relocate.
