Summary
In the City of Council Bluffs, a bar, club or other place of public entertainment cannot run sound above 90 dBA where customers stand unless it posts a hearing-impairment warning sign at every public entrance, under CBMC 4.50.060.
Places of Public Entertainment. Operating, playing or permitting the operation or playing of any radio, television, phonograph, drum, musical instrument, sound amplifier or similar device which produces, reproduces or amplifies sound in any place of public entertainment at a sound level greater than ninety (90) dBA as read by the slow response on a sound level meter at any point that is normally occupied by a customer, unless a conspicuous and legible sign is located outside such place, near each public entrance, stating, "WARNING, SOUND LEVELS WITHIN MAY CAUSE PERMANENT HEARING IMPAIRMENT";
Full Breakdown
CBMC 4.50.060's Places of Public Entertainment clause targets amplified sound inside venues rather than at the property line. It is unlawful to operate, play or permit the operation of any radio, television, phonograph, drum, musical instrument, sound amplifier or similar device that produces, reproduces or amplifies sound in a place of public entertainment at a level greater than 90 dBA, read on the slow response of a sound level meter, at any point normally occupied by a customer. A venue avoids the violation only if it posts a conspicuous, legible sign near each public entrance stating, "WARNING, SOUND LEVELS WITHIN MAY CAUSE PERMANENT HEARING IMPAIRMENT." This is the one prohibited act in the chapter for which CBMC 4.50.110 allows a person's own invitation onto the property to bar an emergency noise-halt order, since patrons voluntarily enter a posted venue.
The clause operates independently of the chapter's property-boundary sound-level table in CBMC 4.50.080, so a bar can still face a separate complaint if its bass or PA system carries across a real property boundary into a residential area under the Loudspeakers or general Noise Disturbance clauses. The chief building official and Council Bluffs police department enforce the chapter under CBMC 4.50.040.
Violations & Fines
Operating a venue over 90 dBA without the required warning sign is a nuisance under CBMC 4.50.110, subject to CBMC 8.54's penalties: a criminal conviction carries the fine under CBMC 8.02.020, or the city attorney may pursue a civil municipal infraction under CBMC 1.95.020, which imposes $750 for a first offense and $1,000 for each subsequent offense, plus surcharge and court costs, with each day of operation a separate violation.
