Amplified music is squarely covered by Harford County Code § 193-8, which names radios, phonographs, musical instruments, and any device for producing or reproducing sound. Between 11 p.m. and 6 a.m., that sound cannot be audible more than 50 feet away on residential property. During the day and evening, Maryland's COMAR 26.02.03.02 caps residential noise at 65 dBA at the property line, dropping to 55 dBA at night. Bel Air and Havre de Grace require permits for outdoor amplified events and set their own conditions. The Sheriff's Office enforces county complaints and can issue a civil fine.
