Prohibited noise disturbances include amplified music, loudspeakers, and public address systems that are audible beyond the property line during quiet hours (10 PM to 7 AM weekdays, 10 PM to 8 AM weekends and holidays). Power tools, lawn mowers, and similar equipment are restricted to daytime hours only. Vehicle horns, car alarms, and other audible signals used except as warning devices are also regulated.
