Southaven, MS Noise from Specific Sources: Generator Noise (2026)

Southaven Code § 10-122 lists specific unlawful noises, and two of them reach engine-driven equipment such as a portable or standby generator. Subsection (6) makes it unlawful to operate any noise-creating blower or power fan or any internal combustion engine whose operation causes noise due to the explosion of operating gases or fluids, unless the noise from the blower or fan is muffled and the engine is equipped with a muffler device sufficient to deaden the noise. Subsection (7) bars discharging into open air the exhaust of any steam engine, stationary internal combustion engine, motorboat or motor vehicle except through a muffler or other device that effectively prevents loud or explosive noises.

Both subsections carry the same carve-out: they do not apply to normal industrial operations on property within an M-1 light industrial district or an M-2 heavy industrial district. Section 10-93(11) separately exempts construction and normal operations in those districts to the extent the resulting noise does not exceed seventy (70) dBA at the property boundary.

Emergency use is treated differently. Section 10-93(4) exempts any mechanical device, apparatus or equipment related to or connected with emergency or emergency work, and the chapter defines emergency work to include work by private or public utilities restoring utility service. Internal combustion engines used for construction, agricultural operations and crop protection lose their exemptions under Sections 10-93(5) through (7) if not equipped with suitable exhaust and intake silencers in good working order. Beyond these rules, Section 10-121 bars any loud, unnecessary or unusual noise that disturbs the peace, and the chief of police or his designee enforces the chapter under Section 10-141.
