Logan, UT Noise from Specific Sources: Bar & Nightclub Noise (2026)

Section 8.16.426 of the Logan Municipal Code sets a volume ceiling for any place of public entertainment. No one can operate, play or permit the operation of a radio, television, phonograph, drum, musical instrument, sound amplifier or similar device in such a place at a sound level greater than 95 dBA, read on the slow response of a sound level meter at any point normally occupied by a customer. The ceiling has one built-in escape. A venue that posts a conspicuous and legible sign outside, near each public entrance, warning that the sound levels within can cause permanent hearing impairment is not in violation of this section. The measurement point is inside, where patrons stand, so this rule protects customers rather than neighbors.

Neighbors are protected by other sections, and a bar or club must satisfy all of them. Under § 8.16.412, amplified music between 10:00 P.M. and 7:00 A.M. cannot create a noise disturbance across a real property boundary or within a noise sensitive zone. Under § 8.16.600, sound from private property cannot exceed the receiving zone limits when measured at the property boundary of the receiving land zone. In C1, C2 and C3 districts that is 60 dBA from 10:00 P.M. to 7:00 A.M. and 65 dBA from 7:00 A.M. to 10:00 P.M. The limits drop to 55 and 60 dBA where the sound originates within 100 feet of a hotel, motel or apartment where people normally sleep. A pure tone or impulsive sound reduces every limit by ten dBA under § 8.16.610, which matters for bass-heavy live music and drum kits. Commercial loudspeakers and public address systems face a further bar on creating a noise disturbance across a real property boundary or within a noise sensitive zone under § 8.16.414(B), and between 10:00 P.M. and 7:00 A.M. on a public right of way or public space.

The decibel table and the entertainment ceiling operate independently, so a venue that posts the warning sign still answers to the boundary limits and the nighttime window.
