Waukesha County sets no decibel limit, and Wisconsin has no statewide dB standard. Noise is judged by a 'reasonableness' nuisance test set by your city, village or town. Any numeric dB cap, if it exists, comes from your municipality.
Neither the Waukesha County Code nor Wisconsin statutes establish a measurable decibel threshold for general noise. Instead, enforcement turns on whether noise unreasonably disturbs the peace — the City of Waukesha's Code 12.05 declares 'noise of any kind tending to unreasonably disturb the peace and quiet of persons in the vicinity thereof' a public nuisance, with no dB figure attached. A few larger Wisconsin municipalities have adopted decibel-based ordinances, but that is a local choice. In unincorporated towns the county applies no dB rule; Wis. Stat. 947.01 disorderly conduct governs unreasonably loud conduct. Ask your municipality whether it uses a sound-meter standard.
There is no county dB penalty. Municipal nuisance forfeitures apply under local ordinances; disorderly conduct (947.01) applies where noise provokes a disturbance.
