Do you think CPCB follows Noise Pollution (Regulation and Control) Rules by identifying lawbreakers?As per Central Pollution Control Board (CPCB)'s Noise Pollution (Regulation and Control) Rules, 2000 there are many rules and restrictions of using the loud speakers, horns, musical instruments, etc. The noise is measured by DB (decibel). And there is too much noise pollution due to blow horns by buses, trucks and motorcycles in cities and small towns. I think the local departments of noise pollution control board is completely slept or kept cotton in their ears, so that nothing will be audible and no issues.
Here I'm writing one of those rules as mentioned in the Noise standards, "A loud speaker or a public address system or any sound producing instrument or a musical instrument or a sound amplifier shall not be used at night time except in closed premises for communication within, like auditoria, conference rooms, community halls, banquet halls or during a public emergency."
Then why bands and baaraats at permitted during night with lots of fireworks and full volume sound track in towns? Once I asked a friend in his marriage, he's taken permission from collector and S.P. for bands and fireworks. There is nothing mentioned whether not be used/not in night time. So there is no risk.
