The court order implied that sound should not go beyond the periphery of the public or private place. The order said that the district magistrates were required to categorise areas into industrial, commercial, residential and silence zones. Each area has separate maximum limits for permissible sound levels. The loudspeakers installed in public places cannot have a sound level more than 10 decibels above the ambient noise level at the periphery of a public place and 5 decibels above the ambient noise level at the periphery of a private place. The division bench of Justices Vikram Nath and Abdul Moin had issued the directions on a PIL moved by lawyer Moti Lal Yadav, seeking strict compliance of the Noise Pollution (Regulation and Control) Rules framed in 2000.
