Full Breakdown

City Code § 34-6 bars operating any stationary source of sound, machinery, pumps, fans, compressors, air conditioners, refrigeration equipment, that exceeds the percentile sound levels set by Table I in § 34-12. For AA, TP, I-1, I-2 and I-3 zones (industrial or agricultural), the limit is 70 dBA on the L90 scale and 80 dBA on the L1 scale, applied identically from 7:00 a.m.-10:00 p.m. and 10:00 p.m.-7:00 a.m., unlike residential and commercial districts, which get a 5 dBA nighttime cut. Noise crossing into a stricter district can't exceed that district's lower limit at the boundary, and impulsive sound sources get their limit reduced by 5 dBA.

Violations & Fines

First offense is a Class "a" offense against the City; a second or later violation escalates to a Class "b" offense. A continuous disturbance counts as one offense per day; a non-continuous disturbance can generate multiple same-day charges.

Frequently Asked Questions

Does the industrial noise limit drop at night in Oklahoma City?
No. Table I holds industrial/agricultural zones (AA, TP, I-1, I-2, I-3) at 70/80 dBA both 7 a.m.-10 p.m. and 10 p.m.-7 a.m., unlike residential and commercial zones.
Where does the city measure industrial noise?
At the boundary of the property affected by the sound, or at any point within that property, per § 34-6(a).
Can a business get relief from the industrial noise limit?
Yes: the City Manager can issue a short-term noise permit under § 34-7, capped at three consecutive days per application.
