§ 9-312 Loudspeakers, etc.

No commercial enterprise may broadcast over a loudspeaker or other device so that the sound can be heard more than 100 feet from the boundaries of the building or property where the device is located or, if the device is in a vehicle, more than 100 feet from that vehicle.

The owner, manager, operator, or other person in charge of the building, premises, or vehicle from which the sound emanates is presumed to be responsible in the absence of evidence to the contrary.
