SLOW RESPONSE
Metering function to be used in measurement of sound for determination of enforcement of the objective noise level limits stated within this Section.
SOUND
An oscillation in pressure, particle displacement, particle velocity or other physical parameter, in a medium with internal forces that cause compression, and rarefaction of that medium resulting in air pressure variations perceptible by the human ear. The description of sound may include any characteristic of such sound, including duration, intensity and frequency.
SOUND LEVEL
The unweighted ("flat") or weighted sound pressure level obtained by the use of a sound level meter and frequency weighting network, such A, B or C as specified in the American National Standards Institute specifications for sound level meters (ANSI S1.4). If the frequency weighting employed is not indicated, the A-weighting shall apply.
SOUND LEVEL METER

J. 
Classification Of Use Occupancies. Use occupancies shall be as follows:
1. 
Residential Use. All premises containing habitually-occupied sleeping quarters. However, premises containing transient commercial sleeping quarters are considered commercial use. Hospitals, nursing homes, schools, libraries, fraternity and sorority houses and charges are considered residential uses.
2. 
Public Nuisance. An offense against the public order by any act which annoys, injures, endangers, renders insecure, interferes with or obstructs the rights or property of the whole community or neighborhood or of any considerable number of persons, even though extent of the annoyance, injury or damage may be unequal or may vary in its effect on individuals.
3. 
Commercial. All premises where sales, professional or other commercial activity is legally permitted, except that residentially zoned properties with lawful home occupations are considered residential.
4. 
Industrial. All premises where goods or wares are made, warehoused or stored or where manufacturing is legally permitted.
5. 
Agricultural. All premises which are bona fide farms, golf courses, or which are characterized by farming activities as the primary use of the premises.

K. 
Measurement Methodology. This Section describes acceptable methods of techniques for the measurement and reporting of noise for the purpose of determining compliance with the allowable noise levels listed above.
1. 
Measurement Location. Measurement of sound must be made at the front building line on the property of the noise receptor.
2. 
Calibration. All sound level measuring devices must be calibrated by a certified agency or the City.
3. 
Sound level measurement shall be made with a sound level meter using the A-weighting scale set on "slow" response.
4. 
Sound level meters shall be at least Type II meeting American National Standard Institute (ANSI S1.4-1983 requirements). Persons using the sound levels shall be trained in sound level measurement and the operation of sound level measurement equipment.
5. 
Measurement Procedures. The following procedures must be followed to obtain representative sound level measurements.
a. 
Measurement location must be at least three (3) feet above the ground and not more than ten (10) feet above ground.
b. 
Measurement shall be taken in location on receptor property with line of sight to the noise source if possible.
c. 
Measurements made in sustained winds over ten (10) knots may be subject to review and considered not valid. Precipitation or other sounds which result in a difference of less than ten (10) dBA between the background or ambient noise level and the noise source being measured may also invalidate measurements.
d. 
Measurements must be made with the sound level meters set for "A" weighting and "slow" response.
e. 
Measurements are to be made when possible and appropriate to the noise source over a fifteen-minute period with the sound level meter in the "averaging" or Leq mode. Measurements should be made over a continuous period, unless a transient event which is easily identified, such as an aircraft overflight, occurs. In this case, the averaging period may be paused for the duration of the transient event and the measurement restarted when the transient event sound level is ten (10) dBA below the noise source being measured.
6. 
Date Documentation. A record of all sound level measurements must be completed and signed by the person marking the measurements. The record sheet should include:
a. 
Date.
b. 
Time of measurement.
c. 
Location (street address if possible).
d. 
Noise source.
e. 
Wind speed and direction (measured, estimate or from airport or weather service records).
f. 
Temperature (if readily available).
g. 
Humidity (if readily available).
h. 
Make, model and serial number of sound level meter, date of last certification/calibration.
i. 
Field calibration results.
j. 
Ambient (background) noise level.
k. 
Name of complainant (if available).
L. 
In addition to the subjective standards established above, it shall be presumed that the allowable noise level limits have been violated whenever any noise or sound is projected from one property in the City onto another if such sound, measured at the front building line on the property receiving the sound, exceeds the following decibel standards at a location appropriate to determine the level of disturbance.
