Hamilton County has no numeric decibel standard. Ohio sets none statewide for general noise. Cincinnati's Chapter 909 uses zoning-district dB(A) limits, measured Leq over six minutes, e.g., 55 dB(A) at night in single-family residential zones, 75 in manufacturing.
There is no Hamilton County or statewide Ohio decibel limit for general community noise. Where a numeric standard exists, it is municipal. Cincinnati's Chapter 909 sets maximum permissible sound levels in Leq dB(A) measured over a minimum six-minute period at the receiving property line, varying by zoning district, time of day, and day of week. Sunday–Wednesday single-family residential limits are 60 dB(A) daytime (7 a.m.–7 p.m.) and 55 dB(A) at night; commercial reaches 70/65 and manufacturing 75/70. Townships adopting ORC 505.172 resolutions may set their own thresholds.
Exceeding Cincinnati's table levels is prima facie evidence of a loud-noise violation: a minor misdemeanor, or fourth-degree misdemeanor for a third offense within a year.
