Moore, OK Noise Ordinances: Decibel Limits (2026)

Most of City Code § 10-414's noise prohibitions use a subjective plainly-audible or noise-disturbance standard rather than a decibel number, but the section closes with one specific figure: operating, or permitting the operation of, any device designed for sound production, amplification or reproduction, radios, musical instruments, phonographs, tape recorders, loudspeakers, at any city-owned park in a way that exceeds 65 decibels (65 dB) measured at the boundary of that park is a violation on its own, without needing to prove the sound also disturbed a person.

The code defines a decibel at § 10-412 as a unit equal to 20 times the base-ten logarithm of the ratio of the measured sound pressure to a reference pressure of 20 micropascals, and defines A-weighted sound level as the decibel reading taken on a sound meter using the A-weighting network, denoted dB(A). Organized sporting events are generally exempt from the noise article under § 10-415, but that exemption is expressly withdrawn for sporting events held at a city-owned park, including youth-league regular season games and tournaments, meaning the 65 dB park-boundary limit can still reach amplified PA systems or music at park athletic events. Violations are municipal offenses under § 10-418, charged once per day for a continuous exceedance and separately for each intermittent one.
