Waynesville, MO Noise Ordinances: Amplified Music & Outdoor Sound (2026)

Section 210.150(C), part of Waynesville's broader loud-noise ordinance, targets "any radio, phonograph, tape player, compact disc player, musical instrument or any similar device for producing or amplifying sound" whenever it "disturbs the peace, quiet or comfort of the neighboring inhabitants." The section then builds two bright-line, time-of-day evidentiary standards on top of that general ban. Between 11:00 p.m. and 7:00 a.m., playing such a device so that it is "plainly audible at a distance of fifty (50) feet from the building, structure or outdoor area in which the device is located" is "prima facie evidence of a violation," meaning the audibility distance alone, without further proof of disturbance, supports a citation.

During the day, from 7:00 a.m. to 11:00 p.m., the threshold relaxes to one hundred feet: the same plainly-audible test applies, just at double the nighttime distance. Two carve-outs run through both standards: noise from a permitted outdoor musical event, and noise from a "sanctioned school group musical activity such as a band orchestra, a chorus group and the like," is not unlawful under this subsection even if it exceeds the audibility distance. The same distance-based approach extends to vehicles: a driver who plays a sound-producing or amplifying device in or on a vehicle so that it is audible fifty feet away is separately covered elsewhere in the section, matching the nighttime residential standard.

Waynesville enforces this with a plainly-audible test rather than a decibel meter, so an officer's own observation of audibility at the measured distance is enough evidence to support a citation.
