§ 34-6. - Community sound level standards. (a) Classification of use districts. Land use zoning district classifications shall be as set out in the zoning ordinance distinguishable as residential, commercial, and agricultural/industrial land use classifications, within which sound levels of Table I of Section 34-12 shall be locally measurable and applied by the use of L90, L10, and L1 percentile levels computed within each time interval of all time intervals used to quantify any measurement period for the evaluation of a given alleged violation from a stationary source of sound or as may be otherwise specifically provided in this Chapter. It shall be unlawful for any person to operate or to permit to be operated any stationary source of sound which, during any sound level measurement period time interval thereof when measured at the boundary or at any point within the property affected by such sound: (1) creates a unit percentile sound level (L1) greater than 15 dB(A), above its ambient sound pressure level (L90) limit, as indicated within a given time division of land use classifications of Table I; or (2) creates a 90th percentile sound level (L90) or a tenth percentile sound level (L10) which exceeds limits as set out within a given time division of land use classifications of Table I; (3) sound projected from one use district into another use district of a lesser sound level limit shall not exceed such lesser sound level measured at the boundary of such use district; (4) for any stationary source of sound which emits impulsive sound, the limits set forth in Table I shall be reduced by five dB(A). (b) Sound level measurement. Sound level measurements shall be undertaken with a sound level meter of Type 2 or better as specified in American National Standards Institute Publication SI.4-1971 or its successor publication, using the A-weighted network scale, in conformance with standards thus promulgated. A field use acoustical calibrator shall be used to verify calibration of the sound level meter before and after noise measurements are taken any day. All equipment used in sound level measurement shall be calibrated to standards traceable to the National Bureau of Standards and shall be recalibrated at least once each year, computed from the date of the previous calibration. (c) "Stationary source of sound" means a device which creates sound while fixed in position, including but not limited to residential, commercial, industrial or agricultural machinery, pumps, fans, compressors, air conditioners and refrigeration equipment. (Code 1980, § 34-6; Ord. No. 19581, § 4, 5-29-91; Ord. No. 24138, § 2, 9-28-10)

Oklahoma City Municipal Code § 34-7 Permit.

§ 34-7. - Permit. (a) Application for a permit for relief from noise restrictions designated in this chapter may be made to the City Manager or his authorized representative. Any such application shall be submitted at least ten business days before the date for which the permit is requested, and shall set out clearly the specified location and boundaries where the permit shall apply, the type of noise to be produced as identified in Section 34-4, the location and source of the noise, identification of the individual or individuals responsible for ensuring compliance with the permit, identification of any organization involved in the generation of the noise to be permitted, dates and times for which the permit is requested, and any other information that is pertinent to determining whether a noise permit may be allowed in such a limited manner that the noise would not be a detriment to the public health, comfort, convenience, safety, welfare and prosperity of City residents. If the noise-producing activity is to be conducted on private property, the applicant shall provide proof of permission from the property owner to conduct the noise activity for which the permit is sought. If the noise-producing activity is to be conducted on public property, the applicant may be required to provide or apply for an activity permit. (b) A permit may be granted only upon sufficient and reliable showing in said application that such conditions indicate one or more of the following to be true: (1) additional time is necessary for the applicant to alter or modify his activity or operation to comply with this chapter; (2) the activity, operation, or noise source will be of temporary duration, and cannot be performed in a manner that would comply with other sections of this chapter; or (3) no other reasonable alternative is available to the applicant. (c) A permit may be granted only for an effective time period of three consecutive days or less. A permit may be renewed if an urgent necessity exists, for three consecutive days or less. No permit shall be granted beyond the hours of 7:00 a.m. to 11:00 p.m. in a residential zoning district or a Planned Unit Development or Simplified Planned Unit Development containing use and development regulations of the residential districts described in § 59-6100.1 of the Oklahoma City Municipal Code or 7:00 a.m. to 12:00 midnight in a nonresidential zone. No more than three noise permits shall be issued for the same location within a residential district as described in § 59-6100.1 of the Oklahoma City Municipal Code, or within any Planned Unit Development or Simplified Planned Unit Development containing use and development regulations of the residential districts described in said section during any calendar year, except in cases of urgent necessity. (d) A noise permit shall identify the specific location or boundaries where the permit shall apply, the type of noise as identified in Section 34-4 of this chapter, and the location and source of the noise permitted, the individual or individuals responsible for ensuring compliance with the permit, any organization involved in the generation of the noise to be permitted, dates and times for which the permit is valid, and any other restriction that is pertinent to restrict the noise so as not to be a detriment to the health, comfort, convenience, safety, welfare and prosperity of City residents. A permit shall expressly designate a distance, not to exceed 2,500 feet, beyond which the permittee shall not be permitted to create a noise disturbance or excessive noise. (e) The City Manager or designee may deny a noise permit when it appears that issuing the noise permit would unreasonably and unnecessarily be a detriment to the public health, comfort, convenience, safety, welfare and prosperity of the public. In determining the propriety of the permit request, the City Manager or designee may consider factors including, but not limited to, the following: (1) the zoning of the involved areas; (2) population density; (3) the natural acoustics of the area involved; (4) whether the permit would impact a Noise Sensitive Zone; (5) impact upon traffic, parking and pedestrian rights-of-way; (6) support or objection by adjacent property owners and occupants; (7) prior noise complaints involving the same applicant or location; (8) past compliance or lack of compliance with noise permits; (9) past convictions by the applicant for similar activities in any area of the City; (10) insufficient or incomplete permit application; (11) insufficient time to process the application; (12) false or misleading information on the application. (f) A denial of a permit application shall be issued in writing and shall specify the reason or reasons for denial. (g) When a citation for violation of the terms of a noise permit is issued, such permit shall be deemed automatically revoked. (h) The permittee shall maintain a legible copy of the permit at the location and during the period of time for which the permit has been issued. Failure to maintain the permit is a violation. (Code 1970, § 21-24.5; Code 1980, § 34-7; Ord. No. 24138, § 2, 9-28-10; Ord. No. 24838, § 2, 3-4-14)

§ 34-9. - Violation procedures. (a) The procedures for enforcing the provisions of this chapter pertaining to stationary sources of sound are as follows: (1) in lieu of filing a complaint with the Municipal Court, the enforcement officer responsible for enforcement of any provision of this chapter may issue an order requiring abatement of any source of sound alleged to be in violation of this chapter within a reasonable time period. A reasonable time is such length of time as may fairly, properly, and reasonably be allowed or required having regard to the nature of the noise level and the attending circumstances. (2) an abatement order shall not be issued when the enforcement officer has reason to believe that there will not be compliance with the abatement order. (3) an abatement order is only applicable to noise violations from a stationary source of sound and is not applicable to any other violation of this chapter. (b) In order to implement and enforce this chapter and for the general purpose of noise abatement and control, the enforcement officer or his representative shall have, in addition to any other authority vested in him, the power to: (1) upon presentation of proper credentials, enter and inspect any private property or place and inspect any report or records at any reasonable time when granted permission by the owner, or by some other person with apparent authority to act for the owner. When permission is refused or cannot be obtained, a search warrant may be obtained from a court of competent jurisdiction upon showing of probable cause to believe that a violation of this chapter may exist. Such inspection may include administration of any necessary tests. (2) stop any motor vehicle, motorcycle, or motorboat reasonably suspected of violating any provision of this chapter, and issue a notice of violation or abatement order which may require the motor vehicle, motorcycle, or motorboat to be inspected or tested as the enforcement officer may reasonably require.
