Summary
Norman limits any 'enclosed place of public entertainment,' meaning bars and nightclubs, to 90 dB(A) measured at a customer's normal spot unless a hearing-warning sign at least 225 square inches is posted at every entrance. Even with a sign, the venue still cannot violate the underlying NCC 16-205 district noise limits. Violations bring fines under the City's penalty schedule.
Enclosed place of public entertainment. Operating or permitting to be operated in any place of public entertainment any loudspeaker or other source of sound with produces, at a point that is normally occupied by a customer, maximum sound levels of 90 dB(A) or greater as read with the slow response on a sound level meter, unless a conspicuous and legible sign at least 225 square inches in area is posted near each public entrance stating: "WARNING: SOUND LEVELS WITHIN MAY CAUSE HEARING IMPAIRMENT." This provision shall not be construed to allow the operation of any loudspeaker or other source of sound in such a manner as to violate NCC 16-205.
Full Breakdown
'" That signage does not create blanket cover, since the same clause "shall not be construed to allow the operation of any loudspeaker or other source of sound in such a manner as to violate NCC 16-205," the underlying district-boundary decibel limits that reach 70-75 dB(A) daytime for commercial zones and fall to 55-60 dB(A) at night. m.

Violations & Fines
A nightclub or bar cited for exceeding the 90 dB(A) indoor threshold without the required warning sign, or for noise crossing the property line above the NCC 16-205 commercial limit, faces a fine and/or imprisonment under the City's penalty schedule in NCC 16-211, with every night of operation in violation charged separately, and repeat offenders risk nuisance injunction proceedings under NCC 16-212.
