(Ord. 88-13, 1988)
A. 
For the purposes of this chapter certain words and phrases used herein are defined as follows:
"'A' Band level"
is the total sound level of all noise as measured with a sound level meter using the 'A' weighing network. The unit of measurement is the dB(A).
"Ambient noise"
is the all-encompassing noise associated with a given environment, being usually a composite of sounds from many sources, near and far.
"Band pressure level"
of sound for a specified frequency band is the sound pressure level for the sound contained within the restricted band. The reference pressure must be specified.
"Bel"
is a unit of level when the base of logarithm is ten. Use of the bel is restricted to levels of quantities proportional to power.
"Cycle"
is the complete sequence of values of a periodic quantity that occur during a period.
"Decibel"
is one-tenth of a bel and is a unit of level when the base of the logarithm is the tenth root of ten, and the quantities concerned are proportional to power.
"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.
"Frequency of a function periodic in time"
is the reciprocal of the primitive period. The unit is the cycle per unit time and must be specified.
"Microbar"
is a unit of pressure commonly used in acoustics and is equal to one dyne per square centimeter.
"Period of a periodic quantity"
is the smallest increment of time for which the function repeats itself.
"Periodic quantity"
is an oscillating quantity, the values of which recur for equal increments of time.
"Person"
is any person, person's firm, association, co-partnership, joint venture, corporation or any entity public or private in nature.
"Sound analyzer"
is a device for measuring the band-pressure level or pressure spectrum level of a sound as a function of frequency.
"Sound-level meter"
is an instrument including a microphone, an amplifier, an output meter, and frequency weighing networks for the measurement of noise and sound levels in a specified manner.
"Sound pressure level,"
in decibels, of sound is twenty times the logarithm to the base ten of the ratio of the pressure of this sound to the reference pressure, which, reference pressure must be explicitly stated.
"Spectrum"
is a function of time and is a description of its resolution into components, each of different frequency and usually of different amplitude and phase and is also used to signify continuous range of components usually wide in extent within which waves have some specified characteristics such as "audio-frequency spectrum" and is also applied to functions of variables other than time.
B. 
All technical definitions are in accordance with American Standard S1.1960 entitled Acoustical Terminology.
(Ord. 88-13, 1988)
The standards which shall be considered in determining whether a violation of this chapter exists shall include, but shall not be limited to, the following:
1. 
The volume of the noise;
2. 
The intensity of the noise;
3. 
Whether the nature of the noise is usual or unusual;
4. 
Whether the origin of the noise is natural or unnatural;
5. 
The volume and intensity of the background noise, if any;
6. 
The proximity of the noise to residential sleeping facilities;
7. 
The nature of the area within which the noise emanates;
8. 
The density of inhabitation of the area within which the noise emanates;
9. 
The time of the day or night the noise occurs;
10. 
The duration of the noise;
11. 
Whether the noise is recurrent, intermittent or constant; and
12. 
Whether the noise is produced by a commercial or non-commercial activity.
(Ord. 88-13, 1988)
A. 
It shall be unlawful to project a sound or noise, excluding noise emanating from cars, aircraft, trucks or motorcycles, from one property into another, within the boundary of a use area which exceeds either limiting noise spectra set forth in Table I, following.
B. 
Sound of noise projecting from one use area, into another use area with a different noise level limit, shall not exceed the limits of the district into which the noise is projected.
C. 
1. 
The measurement of sound or noise shall be made with a sound level meter and octave band analyzer meeting the standards prescribed by the American Standards Association. The instruments shall be maintained in calibration and good working order. Octave band corrections may be employed in meeting the response specification. A calibration check shall be made of the system at the time of any noise measurement. Measurements recorded shall be taken so as to provide a proper representation of the noise source. The microphone during measurement shall be positioned so as not to create any unnatural enhancement or diminution of the measured noise. A windscreen for the microphone shall be used when required. Traffic, aircraft and other transportation noise sources and other background noises shall not be considered in taking measurements except where such background noise interferes with the primary noise being measured.
2. 
The slow meter response of the sound level meter shall be used in order to best determine that the average amplitude has not exceeded the limiting noise Spectra set forth in Table I following.
3. 
The measurement shall be made at the property line of the property on which such noise is generated, or perceived as appropriate, five feet above ground.
4. 
In the case of an elevated or directional sound or noise source, compliance with the noise limits is to be maintained at any elevation at the boundary.
