A. Amplified sound reproduction device. If the source of sound is an amplified sound reproduction device, and the complainant states that the rhythmic bass component of the music is disturbing within their residence, then the noise enforcement officer may take sound level measurements from inside the residence of the complainant. No person shall cause, suffer, allow or permit the operation of any amplified source of sound in such a manner that it raises the total sound level above the permissible sound level limits set forth in the table in this section when measured inside the residence of the complainant. These sound level measurements shall be conducted under the “C” band level with the sound level meter set for “C” weighting, “fast” response. Such measurements shall not be taken in areas which receive only casual use such as hallways, closets and bathrooms. For the purposes of these measurements, the neighborhood residual sound level is that sound level which is measured in the residence when the sound source under investigation is not prominent, or in a room on the same floor that is relatively unaffected by the sound source under investigation.
Noise Zone | Time Interval | Allowable Noise Level |
I | 10:00 p.m. to 7:00 a.m. | 45 dB(C) |
7:00 a.m. to 10:00 p.m. | 55 dB(C) |
It is unlawful for any person at any location within the city or its extraterritorial jurisdiction to create any noise or to suffer, allow or permit the creation of any noise on property owned, leased, occupied or otherwise controlled by such person, which causes the noise level on any property to exceed the noise standards as a measured average over any 5 minute period of measurement, or the noise standard plus 10 dB(C) at any time.
The measurement of noise levels shall be taken from the affected property as deemed most appropriate by the responding officer. The measured noise levels are based on the noise zone which is the source of the noise.
B. Sound trucks; loudspeakers; other sound amplifiers. It is unlawful to play, operate or use any device known as a sound truck, loudspeaker or sound amplifier, radio or phonograph with a loudspeaker or sound amplifier or any instrument of any kind or character which emits loud and raucous noises and is attached to and upon any vehicle unless such person in charge of such vehicle shall have first applied to and received a permit from the Chief of Police or designee to operate any such vehicle so equipped. Such permit shall be granted unless the Chief of Police or designee believes the activity will disturb the public peace.
C. Motor vehicle repair. It shall be unlawful for any person within any residential area of the city to repair, rebuild or test any motor vehicle (between the hours of 10:00 p.m. of 1 day and 5:00 a.m. of the next day) in such a manner that a reasonable person of normal sensitiveness residing in the area is caused discomfort or annoyance.
D. Schools, churches and hospitals. It shall be unlawful for any person to create any noise on any street, sidewalk or public place adjacent to any school, institution of learning or church while the same is in use or adjacent to any hospital, which noise unreasonably interferes with the workings of such institution or which disturbs or unduly annoys patients in the hospital; provided that conspicuous signs are displayed in such streets, sidewalk or public place indicating the presence of a school, church or hospital.
E. Watercraft. Noise emitted from watercraft as defined in A.R.S. § 5-310 shall be regulated pursuant to the provisions set forth in the Arizona Administrative Code R12-4-516.
