In order to control unnecessary, excessive and annoying noise and vibration in the City of Gardena, it is hereby declared to be the policy of the City to prohibit such noise and vibration generated from or by all sources as specified in this chapter. It shall be the policy of the City to maintain quiet in those areas which exhibit low noise levels and to implement programs aimed at reducing noise in those areas within the City where noise levels are above acceptable values.
It is determined that certain noise levels and vibrations are detrimental to the public health, welfare and safety, and are contrary to public interest. Therefore, the City Council does ordain and declare that creating, maintaining, causing or allowing to be created, caused or maintained, any noise or vibration in a manner prohibited by or not in conformity with the provisions of this chapter, is a public nuisance and shall be punishable as such. (Ord. 1683 § 1, 2006; Urg. Ord. 1682 § 1, 2006; prior code § 4-8.01)

C. In the event the ambient noise level exceeds the noise standard, the ambient noise level shall become the noise standard. (Ord. 1683, 2006; Urg. Ord. 1682, 2006)
A. The following interior noise standards, unless otherwise specifically indicated, shall apply to all residential dwellings with windows in their normal seasonal configuration, where such dwelling is the receiver of intrusive noise:
Allowable Interior Noise Level
B. No person shall operate or cause to be operated, any source of sound at any location within the incorporated City or allow the creation of any noise on property owned, leased, occupied or otherwise controlled by such person, which causes the noise level when measured within any residential dwelling, either incorporated or unincorporated, to exceed the noise standards of paragraph (A).
Upon receipt of a complaint from a citizen of noise disturbance that is not a Prohibited Act set forth in Section 8.36.070, the City or its agent, equipped with sound level meter satisfying the requirements specified in Section 8.36.020, shall investigate the complaint. The investigation shall consist of a measurement and the gathering of data to adequately define the noise problem and shall include the following:

2. Measurements shall be made at the location with the highest perceived noise level including, but not limited to, locations identified by the complainant as being most severely affected by noise. In general, the microphone shall be located five feet above the ground or finished surface, and ten feet or more from the nearest reflective surface, where possible. However, in those cases where another elevation or microphone height is deemed appropriate (e.g., a second floor facade or balcony), it shall be utilized. If the noise measurement is to be obtained behind a noise barrier (e.g., a fence or wall) the microphone shall be located no closer than five feet from the noise barrier, where possible. If the noise complaint is related to interior noise levels, interior noise measurements shall be made within the affected residential unit. The measurements shall be made at a point at least four feet from the wall, ceiling, or floor nearest the noise source, with windows in the normal seasonal configuration. Calibration of the measurement equipment, utilizing an acoustical calibrator, shall be performed immediately prior to recording any noise data.
3. If possible, the ambient noise shall be measured at the same location utilized in paragraph (2), with the alleged offending noise source inoperative. If for any reason the alleged offending noise source cannot be shut down, the ambient noise must be estimated by performing a measurement in the same general area of the source but at a sufficient distance such that the noise from the source but at a sufficient distance such that the noise from the source is inaudible. (Ord. 1683 § 1, 2006; Urg. Ord. 1682, 2006)
