Loudspeakers, bands, and outdoor events across Williamson County answer to city noise ordinances and to Tenn. Code Ann. §39-17-305, which makes unreasonable noise a Class C misdemeanor. Franklin's ordinance 11-402 requires amplified sound and live bands to stay at a reasonable level, with tighter limits between 11 p.m. and 7 a.m., and public events at parks and downtown typically need a city permit setting volume and end-time conditions. Brentwood's Chapter 42 adds a 70-decibel ceiling near homes. A backyard party in the unincorporated county needs no permit but still cannot disturb the neighborhood.
