It is the intent of Tremonton City to regulate noise to minimize disturbances or public nuisances.

This Chapter contains standards of measurement hereinafter set forth, which take into account the latest scientific advance in noise measurement and control while at the same time, preserving the common sense and common law determination of what constitutes a disturbance or public nuisance. Notwithstanding, sound level measurements, while universally desirable, shall not be required to demonstrate violation of this Chapter if other evidence or testimony establishes the creation of a disturbance or public nuisance.

Note: Noises Not Covered by Noise Ordinance: The City's noise ordinance does not cover noise from a train/railroad, aircraft, general farm equipment, or general road noise.

The following shall be exempt from noise restrictions:

A.

Public Safety response to duties and emergencies;

B.

Notification of Emergency Services and Natural Disasters using a broadcast siren;

C.

Emergency maintenance of area infrastructures, included are, roads, water systems, sewer systems, electrical power, communications, storm drains, irrigation systems, etc.;

D.

Special events approved by the City Council or sponsored by the City or Box Elder County; and

E.

Construction activities during the hours of six (6) o'clock a.m. and ending no later than ten (10) o'clock p.m., daily.

Any person who violates or causes the violation of any of the regulations of this Chapter shall be guilty of a class C misdemeanor and upon conviction thereof shall be punished as provided by law. See Section 1.01.040 of this Title.

A.

In no event shall the peak intensity of sound exceed a sound level in excess of the following limits, measured in decibels, using, unless otherwise mentioned, the "A" frequency weighted and the "slow" response characteristic of a sound level meter conforming to all respects to American National Standards Institute (ANSI) Standard S1.4-current version, as revised for type one (1) or type two (2) instruments.

B.

The microphone or devise used to measure the intensity of a noise may be placed at any point on the property line (if the noise source radiates into private property) or at any point fifty (50') feet distance from the noise source being measured and shall be at least five (5') feet from any wall and not less than three (3') feet above the ground. If it is not possible to measure five (5') feet from a wall, five (5) dB variance shall be allowed. When measurements are made inside buildings or enclosures, readings may be obtained from any area to which persons may have access.

C.

The following limits refer to the largest reading obtained, using the above procedure:

Continuous and intermittent noises, sounds of commerce and industry:⁴

Continuous noises, public disturbance: Vehicles, machinery, motors, equipment, and music:⁴

Intentionally caused noises: Vehicles, machinery, motors, equipment, and music:

Impulse noises, an "on" cycle of ten (10) percent or less and a maximum continuous duration of two (2) seconds: Example: A gunshot.

² Note: "Day" shall be from 6:00 a.m. to 10:00 p.m.

³ Note: "Night" shall be from 10:00 p.m. to 6:00 a.m.

⁴ Note: Maximum Exposure time at 85 dB is eight (8) hours.
