Troy, MI Noise Ordinances: Amplified Music & Outdoor Sound (2026)

5, addresses amplified sound in two subsections. Subsection (j), Devices to Attract Attention, declares unlawful "the use of any drum, loudspeaker, amplifier or other instrument or device for the purpose of attracting attention for any purpose," a flat prohibition that, unlike the Chapter's disturbance-based clauses, does not require proof that anyone was actually annoyed. Subsection (l), Sound Trucks, separately bars operating "a sound truck with radio or amplifier within the City" without first obtaining a permit from the City Council, so a business or advocacy group wanting to run a mobile PA system through Troy's streets must apply to the Council itself, not a department, before doing so.

5(m) carves out one relevant exception: "the reasonable use of stationary amplifiers or loud speakers in the course of public addresses which are non-commercial in character" is not enforced against, which shelters things like a non-commercial rally speech but not a business using a loudspeaker to draw customers. Together the two subsections mean fixed loudspeaker or amplifier use to attract attention is banned outright, and any sound-truck operation needs Council sign-off regardless of volume, a stricter posture than the volume-and-disturbance test Chapter 88 applies to radios and musical instruments under subsection (b).
