NOISE REGULATION
(Added by Ord. No. 144,331, Eff. 3/2/73.)


ARTICLE 1
GENERAL PROVISIONS

SEC. 111.00. DECLARATION OF POLICY.
It is hereby declared to be the policy of the City to prohibit unnecessary, excessive and annoying noises from all sources subject to its police power. At certain levels noises are detrimental to the health and welfare of the citizenry and in the public interests shall be systematically proscribed.

 

SEC. 111.01. DEFINITIONS.
Unless the context otherwise clearly indicates, the words and phrases used in this chapter are defined as follows:

(a) "Ambient Noise" is the composite of noise from all sources near and far in a given environment, exclusive of occasional and transient intrusive noise sources and of the particular noise source or sources to be measured. Ambient noise shall be averaged over a period of at least 15 minutes at a location and time of day comparable to that during which the measurement is taken of the particular noise source being measured. (Amended by Ord. No. 156,363, Eff. 3/29/82.)

(b) "Commercial Purpose" is the use, operation, or maintenance of any sound amplifying equipment for the purpose of advertising any business, goods, or services, or for the purpose of attracting the attention of the public to, advertising for, or soliciting patronage or customers to or for any performance, show, entertainment, exhibition, or event, or for the purpose of demonstrating such sound equipment. (Amended by Ord. No. 156,363, Eff. 3/29/82.)

(c) "Decibel" (dB) is a unit of level which denotes the ratio between two (2) quantities which are proportional to power; the number of decibels corresponding to the ratio of two (2) amounts of power is ten (10) times the logarithm to the base (10) of this ratio. (Amended by Ord. No. 156,363, Eff. 3/29/82.)

(d) "Emergency Work" is work made necessary to restore property to a safe condition following a public calamity, or work required to protect persons or property from an imminent exposure to danger, or work by private or public utilities when restoring utility service. (Amended by Ord. No. 156,363, Eff. 3/29/82.)

(e) "Impulsive Sound" is sound of short duration, usually less than one second, with an abrupt onset and rapid decay. By way of example "impulsive sound" shall include, but shall not be limited to, explosions, musical base drum beats, or the discharge of firearms. (Amended by Ord. No. 156,363, Eff. 3/29/82.)

(f) "Motor Vehicle" includes, but shall not be limited to, automobiles, trucks, motorcycles, minibikes and go-carts. (Amended by Ord. No. 156,363, Eff. 3/29/82.)

(g) "Noncommercial Purpose" is the use, operation, or maintenance of any sound equipment for other than a "commercial purpose". "Non-commercial purpose" shall mean and include, but shall not be limited to, philanthropic, political, patriotic, and charitable purposes. (Amended by Ord. No. 156,363, Eff. 3/29/82.)

(h) "Octave Band Noise Analyzer" is an instrument for measurement of sound levels in octave frequency bands which satisfies the pertinent requirements for Class II octave band analyzers of the American National Standard Specifications for Octave, Half-Octave, and Third-Octave Band Filters, S1. 11-1966 or the most recent revision thereof. (Amended by Ord. No. 156,363, Eff. 3/29/82.)

(i) "Person" is a person, firm, association, co-partnership, joint venture, corporation, or any entity, private or public in nature. (Amended by Ord. No. 156,363, Eff. 3/29/82.)

(j) "Sound Amplifying Equipment" (Amended by Ord. No. 156,363, Eff. 3/29/82.) is any machine or device for the amplification of the human voice, music or any other sound, but shall not include:

1. Automobile radios, stereo players or television receivers when used and heard only by the occupants of the vehicle in which the same is installed.

2. Radio, stereo players, phonographs or television receivers used in any house or apartment within any residential zone or within 500 feet thereof.

3. Warning devices on emergency vehicles.

4. Horns or other warning devices authorized by law on any vehicle when used for traffic purposes.

(k) "Sound Level" (Noise level) in decibels (dB) is the sound measured with the "A" weighting and slow responses by a sound level meter; except for impulsive or rapidly varying sounds, the fast response shall be used. (Amended by Ord. No. 156,363, Eff. 3/29/82.)

(l) "Sound Level Meter" is an instrument including a microphone, an amplifier, an output meter, and "A" frequency weighting network for the measurement of sound levels which satisfies the pertinent requirements for Type S2A meters in American Standard Specifications for sound level meters in S1.4-1971 or the most recent revision thereof. (Amended by Ord. No. 156,363, Eff. 3/29/82.)

(m) "Sound Truck" is any motor vehicle, or any other vehicle regardless of motive power, whether in motion or stationary, which carries, is equipped with, or which has mounted thereon, or attached thereto, any sound amplifying equipment. (Amended by Ord. No. 156,363, Eff. 3/29/82.)

(n) Supplementary Definitions of Technical Terms. Definitions of technical terms not defined herein shall be obtained from American Standard Acoustical Terminology S 1-1-1971 or the most recent revision thereof. (Amended by Ord. No. 156,363, Eff. 3/29/82.)

 

SEC. 111.02. SOUND LEVEL MEASUREMENT PROCEDURE AND CRITERIA.(Title amended by Ord. No. 156,363, Eff. 3/29/82.)

(a) (Amended by Ord. No. 156,363, Eff. 3/29/82.) Any sound level measurement made pursuant to the provisions of this chapter shall be measured with a sound level meter using the "A" weighting and response as indicated in Section 111.01(k) of this article.
Except when impractical, the microphone shall be located four to five feet above the ground and ten feet or more from the nearest reflective surface. However, in those cases where another elevation is deemed appropriated [sic], the latter shall be utilized.
Interior sound level measurements shall be made at a point at least four feet from the wall, ceiling, or floor nearest the noise source.
Calibration of the sound level meter, utilizing an acoustic calibrator shall be performed immediately prior to recording any sound level data. The ambient noise level and the level of a particular noise being measured shall be the numerical average of noise measurements taken at a given location during a given time period.

(b) (Amended by Ord. No. 156,363, Eff. 3/29/82.) Where the sound alleged to be offending is of a type or character set forth below, the following values shall be added to the sound level measurement of the offending noise:

1. Except for noise emanating from any electrical transformer or gas metering and pressure control equipment existing and installed prior to the effective date of the ordinance enacting this chapter, any steady tone with audible fundamental frequency or overtones have 200 Hz..................+5

2. Repeated impulsive noise...............................................................+5

3. Noise occurring more than 5 but less than 15 minutes in any period of 60 consecutive minutes between the hours of 7:00 a.m. and 10:00 p.m. of any day.....................................................................................-5

4. Noise occurring five minutes or less in any period of 60 consecutive minutes, between the hours of 7:00 a.m. and 10:00 p.m. of any day ....-5

(Amended by Ord. No. 161,574, Eff. 9/8/86.)

(c) For those cases where an objectionable noise is clearly audible, but where the level of ambient noise does not permit direct quantative sound level "A" measurements of the objectionable noise, sound measurements may be performed utilizing an octave band sound analyzer to determine sound level "A" limits as indicated in the Table I below. This table is used to convert the sound pressure level meter readings in dB for each band to SPL in dB(A) for each band.
