The following words, terms, and phrases, when used in this article, shall have the meanings ascribed to them in this section, unless the context of their usage clearly indicates another meaning:
Daytime hours
means the hours from 7:00 a.m. on one day and 10:00 p.m. the same day for residential properties or areas and 6:00 a.m. on one day and midnight on the same day for nonresidential properties or areas.
dB(A)
means the intensity of a sound expressed in decibels.
Emergency
means any occurrence or set of circumstances involving actual or imminent physical trauma or property damage or loss that demands immediate action.
Emergency work
means any work performed for the purpose of:
(1) 
Preventing or alleviating the physical trauma or property damage threatened or caused by an emergency;
(2) 
Restoring property to a safe condition following a fire, accident, or natural disaster;
(3) 
Protecting persons or property from exposure to danger; or
(4)

Nonresidential property/areas
means any real property that is not included in the definition of residential property as defined in this section. Without limitation, the term includes properties that have been zoned other than as residential property, and properties that are devoted to public purposes, such as public parks.
Plainly audible
means any sound that can be detected by a person using his or her unaided hearing faculties. For example, if the sound source under investigation is a portable or personal vehicular sound amplification or reproduction device, the enforcement officer need not determine the name of the song, specific words or the artist performing it. The detection of the rhythmic bass component of the music is sufficient to constitute a plainly audible sound.

Residential property/areas
means any real property where a residence is located.
Streets
shall be defined as being in the same category as the surrounding property. In the case of residential properties/areas which are across the street from nonresidential properties/areas, the street shall be considered to be in a residential area.
(Ordinance 117, sec. 8.71.001, adopted 7/9/19)
(a) 
It shall be unlawful for any person to make, continue, or cause to be made or continued any loud, unnecessary, or unusual noise that annoys, disturbs, injures, or endangers the comfort, repose, health, peace, or safety of others. In determining whether a noise is loud, unnecessary, or unusual, the following factors shall be considered: time of day; proximity to residential properties/areas as defined above; whether the noise is recurrent, intermittent, or constant; the volume and intensity; whether the noise has been enhanced in volume or range by any type of electronic or mechanical means; and whether the noise is subject to being controlled without unreasonable effort or expense to the creator thereof.
(b) 
It shall be unlawful for any person to make, assist in making, permit, continue, cause to be made or continued, or permit the continuance of any sound that either exceeds the maximum permitted sound levels specified in section 8.02.006 of this article or, for purposes of sections 8.02.003, 8.02.004, and 8.02.005 of this article, otherwise unreasonably disturbs, injures, or endangers the comfort, repose, health, peace, or safety of others.

The operation of any such sound amplifier in such a manner as to be plainly audible at a distance of 50 feet or more from a vehicle shall be presumed to be violative of this section. The operation of any such sound amplifier in such a manner that bass sounds are plainly audible at a distance of 50 feet or more from the property line of a property or premises in which the amplification is located shall be presumed to be violative of this section.
(b) 
It is an affirmative defense to prosecution under this section that the sound source is a motor vehicle and that (i) the motor vehicle is a mobile sound stage or studio that is being used on a stationary basis at a location not situated upon any street for the purpose of providing sound, during daytime hours, for an event or function, and (ii) the use is in compliance with all other provisions of this article.
(Ordinance 117, sec. 8.71.004, adopted 7/9/19)

In any prosecution for a violation of this section 8.02.005, the fact that any loud animal noise which disturbed any person and which occurs in residential areas either (i) during nighttime hours, or (ii) when none of the residents who reside at the place where the animal or bird is being kept are at home, shall create a rebuttable presumption that such noise was in violation of this article.
(c) 
In any prosecution for a violation of this section 8.02.005, the fact that any animal or bird has been allowed or permitted to persistently and chronically violate this section, as demonstrated by the issuance of two or more citations and/or the receipt of two or more complaints from more than one household within a two-month period, shall create a rebuttable presumption that such noise was in violation of this article.

(b) 
Any sound that exceeds the dB(A) levels set forth in this section under the conditions and measurement criteria set forth in this article is a violation of this article. Evidence that an activity or sound source produces a sound that exceeds the dB(A) levels specified in this section shall be prima facie evidence of a sound nuisance that unreasonably disturbs, injures, or endangers the comfort, repose, health, peace, or safety of others in violation of this article.
(c) 
Regardless of the measurable dB(A) level established above and measured as provided in section 8.02.007 below, the generator of any sound of such a nature as to cause persons occupying or using any property other than the property upon which the sound is being generated to experience physically detectable sound, vibrations or resonance at a distance of fifty feet (50') from the source of the sound (measured as set out below) caused by the sound shall also be prima facie evidence of a sound that unreasonably disturbs, injures, or endangers the comfort, repose, health, peace, or safety of others in violation of this article.
(Ordinance 117, sec. 8.71.006, adopted 7/9/19)
Whenever portions of this article prohibit sound over a certain decibel limit, measurement shall be made with a Type 1 or Type 2 calibrated sound level meter utilizing the A-weighting scale and the slow meter response as specified by the American Standards Association. Measurements recorded shall be taken so as to provide a proper representation of the sound being measured. The microphone of the meter shall be positioned so as not to create any unnatural enhancement or diminution of the measured sound. A windscreen for the microphone shall be used. Traffic, aircraft, and other transportation noise shall not be considered in taking measurements except where such background noise interferes with the noise being measured and cannot reasonably be distinguished from the primary noise. Measurements of sound generated shall be taken from the curb line of the nearest public street to the property where the sound is generated and taken toward the source of the sound. In the event that there is not at least fifty feet (50') of distance from the building in which sound is being generated and from which sound is being measured, then measurements shall be taken from the street curb line opposite the said building of the nearest public street to the property where the sound is generated.
