Mosinee, WI Noise Ordinances: Amplified Music & Outdoor Sound (2026)

Section 54-193(e) of the Mosinee Code of Ordinances treats unpermitted street amplification as part of the city's loud-and-unnecessary-noise article. Anyone who wants to run a loudspeaker or amplifying device on a city street must first apply to the chief of police for a permit; without one, the use is flatly prohibited. , so no amplified announcement on the street is lawful outside that 12-hour window even with a permit in hand. The chief also has standing authority to deny an application or revoke a permit already granted whenever, in his judgment, the loudspeaker or amplifying device is becoming a nuisance because of its volume, the manner in which it is operated, or where it is located.

A narrower exception in subsection (c)(3) lets people use amplifiers or loudspeakers for noncommercial public addresses without a permit, covering things like political speeches or civic announcements rather than advertising. Commercial advertising broadcast onto the street through a loudspeaker is separately restricted under subsection (b)(3), which also requires that any announcement over a loudspeaker be delivered live by the announcer rather than through a recorded or mechanical device. Enforcement runs through the police department, and because chapter 54 sets no dedicated fine for this subsection, a violation defaults to the city's general penalty in section 1-13: forfeitures of $25 to $500 for a first offense and $50 to $1,000 for a repeat offense within a year, with jail time in default of payment.
