5.48.010 - Declaration of policy.¶
In order to control unnecessary, excessive, and annoying noise in the City of Manhattan Beach, it is hereby declared to be the policy of the City to prohibit such noise generated from or by all sources as specified in this ordinance.
It shall be the policy of the City to maintain and preserve the quiet atmosphere of the City, to implement programs aimed at retaining ambient noise levels throughout the City, and to mitigate noise conflicts. It is determined that certain noise levels are detrimental to the public health, welfare and safety, and are contrary to the public interest. Therefore, creating, maintaining, causing, or allowing to be created, caused, or maintained, any noise in a manner prohibited by the provisions of this chapter is a public nuisance and shall be punishable as such.

"Ambient noise" means the composite of all noise from sources near and far, excluding the alleged intrusive noise source. The ambient noise constitutes the normal or existing level of environmental noise at a given location.
"Amplified sound" means any increase of sound above ambient noise levels by the use of electronic equipment.
"A-weighted noise level" means the noise level in decibels as measured on a sound level meter using the A-weighting network. The level so read is designated in dBA.
"Commercial property" means a parcel of real property which is zoned and used entirely, or partially, for commercial purposes.
"Construction" means any site preparation, assembly, erection, substantial repair, alteration, or similar action, or related services or activities, for or of private property, structures, utilities, or public rights-of-way.
"Cumulative" means an additive period of time composed of individual time segments which may be continuous or interrupted.
"Decibel" means a unit for measuring the amplitude of noise, equal to twenty (20) times the logarithm to the base of ten (10) the ratio of the pressure of the noise measured to the referenced pressure, which is twenty (20) micropascals.
"Dominant noise source" means the most significant source of noise at a given location which is identifiable by the officer.
"Emergency" means any occurrence or set of circumstances involving actual or imminent physical trauma or property damage which demands immediate action.
"Emergency work" means any work performed for the purpose of preventing or alleviating the physical trauma or property damage threatened or caused by an emergency.
"Equivalent noise level (LEE)" means the constant noise level that, in a given situation and time period, contains, the same acoustic energy as the actual time-varying A-weighted noise level.
"Fixed noise source" means a stationary device which creates noise while in a fixed or stationary position including, but not limited to, industrial and commercial machinery and equipment, pumps, fan compressors, generators, air conditioners, and refrigeration equipment.
"Impulsive noise" means a noise of short duration usually of high intensity with an abrupt onset and rapid decay. Impulsive noise sources include but are not limited to impact wrenches, pneumatic hammers, hammering devices, explosions, fire arms and other similar noise sources.

If the ambient LEE exceeds the level in Table 6, then the ambient LEE becomes the exterior noise standard.
C. The ambient noise shall be measured at the same location as the measurement of the alleged intrusive noise with the alleged intrusive noise source not operating. If the operator of the alleged intrusive noise source cannot or will not stop the operation of the alleged noise source then the total noise level measured by the City employee or City's contractor shall be considered to be the alleged intrusive noise if in the opinion of the officer the alleged intrusive noise is the dominant noise sources at the measurement location.
D. If the ambient noise level is measured by stopping the operation of the alleged intrusive noise source, then the alleged intrusive noise source shall be determined by subtracting a value from the total noise level measured at the same location with the alleged intrusive noise source in operation. The values in the following table shall be utilized to determine the intrusive noise level based on the amount by which the noise level decreases when the noise source is turned off.
| Noise Level Decrease with Noise Source Off | Value to Subtract from Total Noise Level to Obtain Intrusive Noise Level |
|---|---|
| 0 | 10 dB |
| 1 | 7 |
| 2 | 4 |
| 3 | 3 |
| 4—5 | 2 |
| 6—9 | 1 |
| 10 or more | 0 |
E. Correction for Character of Sound. For any source of noise which emits a pure tone or contains impulsive noise, the noise standards as set forth in this section shall be reduced by five (5) dB. Examples of impulsive noise include fire alarms, hammering operations, impact wrenches, and other mechanical devices that produce noise levels with a quick onset and delay. Examples of pure tone noises include whistles, bells, and other mechanical devices that emit a tone that is distinguishable by the City employee or contractor.
F. If the measurement location is on a boundary between two (2) different land use classifications, the noise level limit applicable to the more restrictive land use classification plus five (5) dB, shall apply.

An alternate location may be utilized within the property of the complainant if in the opinion of the City employee or agent, the intrusive noise is greater at that location.
B. The microphone shall be located at a minimum of five feet (5′) above the ground, ten feet (10′) or more from the nearest large reflective surface (other than the ground) where possible.

The measurement shall be made at a point at least four feet (4′) from the wall, ceiling, or floor nearest the noise source with the windows open or closed at the option of the unit occupant.
D. The sound level meter shall be calibrated prior to measurement following the meter manufacturer's recommendations with an acoustical calibrator or a piston phone calibrator. Single-tone calibrators operating at one thousand (1,000) Hz shall be acceptable. The sound level meter shall be calibrated following any measurement period. Any measurements made between two (2) subsequent calibration checks that differ by more than one (1) dB shall not be considered valid.
E. A windscreen shall be utilized with the sound level meter in accordance with the meter manufacturer's recommendations. No noise measurements shall be made during periods in which the steady wind speed exceeds twelve (12) mph. No noise measurements shall be made during periods of precipitation.
F. The receiving microphone shall be oriented with respect to the noise source in accordance with the recommendations of the manufacturer of the sound level meter.
