Summary

Minneapolis enforces a special one-third octave band test for low-frequency bass noise when a dB(C) meter can't isolate it: a 10 dB(C) rise above ambient in any one-third octave band counts as a violation.

If separation of low frequency noise cannot be determined with the meter using dB(C) and low frequency tones are clearly audible, a sound level measurement in terms of one-third (1/3) octave band frequencies shall be utilized. If this approach is required, a ten (10) dB(C) increase over ambient levels in any one-third (1/3) octave band due to the amplified music shall be considered a violation of this chapter.

Full Breakdown

City Code § 389.60(a) sets the base noise-violation threshold at 10 dB(C) above ambient in daytime or 5 dB(C) above ambient at night, measured inside the complainant's unit. When a standard dB(C) reading can't separate out low frequency noise but bass tones are clearly audible, inspectors switch to one-third octave band analysis instead. Under that method, a 10 dB(C) increase over ambient in any single one-third octave band, the standard tool for isolating bass and sub-bass frequencies, is itself a violation, regardless of the overall dB(C) reading. The rule targets thumping bass from amplified music and stereo systems that standard weighting can miss.

Violations & Fines

Violations are enforced criminally under § 1.30 or administratively under Chapter 2, plus injunction or abatement remedies; each is treated as a public nuisance under § 389.125.

Frequently Asked Questions

What counts as illegal bass noise in Minneapolis?
If a standard dB(C) meter can't isolate low-frequency noise but bass tones are clearly audible, the city switches to one-third octave band measurement: a 10 dB(C) rise in any one band is a violation.
Where is the noise measured?
For sound from a neighboring property, measurements are taken indoors with doors and windows closed, inside the unit occupied by the person filing the complaint, per § 389.60(a).
Who enforces Minneapolis's noise ordinance?
