This article contains performance and operating standards applicable within the city. These uses must be approved for the site on which they will take place by the appropriate procedures prescribed in Article XI. Once the use is approved for the site, the following procedures and standards must be complied with before commencement of the use and thereafter during its operation.

The following standards shall apply to all uses on incorporated lands in the City of Carrabelle approved under this code.

A.

The following devices and instruments standardized by the American Standards Association shall be used:

S.L.M. Sound Level Meter

V.M.D. Three Component Vibration Measuring Device

A.D.I. Atmospheric Dust Impinger

C.

The following references are cited in this section:

NOTE: Wherever the standards for industrial safety or air contamination cited herein have been superseded or preempted by other regulatory agencies, the more stringent standards shall apply.

Unless otherwise defined herein, all terminology shall be in conformance with applicable publication of the American National Standards Institute, Incorporated (ANSI) or its successor body.

Instrumentation used in making sound level measurements shall meet the following requirements:

A.

Sound level meter. Sound level meters shall be of at least Type 2 meeting ANSI 51.4-1971 requirements. Alternately, a microphone or sound level meter may be used with a magnetic tape recorder and/or graphic level recorder or indicating meter, providing the system meets at least Type 2 ANSI requirements. For measurements requiring octave band analysis, the equipment will additionally meet ANSI 51-11-1966.

B.

Sound level calibrator. The entire sound measurement system shall be calibrated with an acoustic calibrator recommended by the manufacturer and according to the manufacturer's recommended procedures.

C.

Windscreen. An open-call, foam windscreen recommended by the manufacturer of the sound level meter shall be used.

D.

Calibration. The instruments used for acoustical measurements shall be serviced in accordance with the manufacturer's instructions. Before and after a series of measurements, the instrumentation shall be calibrated acoustically according to the manufacturer's instructions and at intervals not exceeding two hours when the instrument is used no longer than a two-hour period.

E.

Meter operation. Unless expressed otherwise in this section, the sound level meter shall be operated in accordance with instrument manufacturer's instruction and as follows:

1.

Microphone location. The microphone shall be located at a height of four feet above the ground level. All microphone positions shall be described in the recording of all data.

2.

Microphone orientation. The microphone shall be oriented in relation to the source of the sound in accordance with instrument manufacturer's instructions. Where the instruction manual is vague or does not include adequate information, a specific recommendation shall be obtained from the manufacturer.

3.

Meter setting. The meter shall be set for the A-weighted network and fast response.

4.

Ambient sound. Measurements shall be made only when the A-weighted ambient sound level, including wind effects and all sources other than that being measured, is at least ten dB lower than the sound level of the source.

F.

Persons selected to conduct sound measurement tests shall have received training in the techniques of sound measurement and the operation of sound measurement instruments.

G.

The technician making direct readings of the meter shall be positioned in relation to the microphone in accordance with the instrument manufacturer's instructions. Where the instruction manual is vague or does not include adequate information, a specific recommendation shall be obtained from the manufacturer.

The following procedure shall be used to determine if a violation exists pursuant to the requirements of this section:

A.

The sound level meter shall be located on the adjacent boundary closest to the noise source or on a lot from which complaint arises, unless specified otherwise.

B.

If a complaint arises from a multi-story structure, the height of the sound level meter shall be adjusted so that it is on a direct line between the noise source and noise receiver.

C.

The microphone shall be at least three feet from any adjacent structure.

D.

Following equipment manufacturer's operation instruction, determine if the sound pressure level in the one-third octave band with the tone exceeds the arithmetic average of the sound pressure level of the two contiguous bands by:

5 dB for center frequencies of 500 Hz and above.

8 dB for center frequencies between 160—400 Hz.

15 dB for center frequencies of 125 Hz or below.

E.

Record readings as follows:

1.

Every ten seconds read the level of the sound level meter.

2.

Record this level on a data sheet at the appropriate level.

3.

After 60 samples, test by the confidence criterion described below. If the samples meet the criterion, then the measurement is complete. If not, then 40 more samples must be taken and the confidence criterion is still not met, additional groups of 50 samples must be completed until the confidence criterion is met.

F.

Test confidence criterion as follows:

1.

Counting down from the top of the data sheet circle the "test samples". After the first 60 samples have been taken, then the 2nd, 6th, and 12th samples from the top are circled.

2.

If those three test samples fall into three continuous levels, then the measurement is complete. Otherwise, another group of samples must be taken and tested again.

3.

If 100 or more samples have been taken, skewing is allowed, The 2 outer test samples (the error limits) can be shifted by one sample (not one level) both in the same direction. This sometimes provides the necessary accuracy without requiring further sampling. However, if the criterion is still not met after skewing, the 50 more samples must be taken and tested.

4.

Once the confidence criterion has been met, the level exceeding ten percent of the measurement period (the second sample circle) has been determined with dB with 95 percent confidence.

G.

As noise source radiates sound, read the maximum deflection of the needle of the sound level meter. If possible, determine and record the minimum sound level during the period of observations.

H.

The following procedure shall be used to determine if a violation exists pursuant to requirements for multi-family dwellings:

1.

The microphone of the sound level meter shall be set at any point 4 feet from wall, ceiling or floor that is radiating noise and at least 3 feet from any adjacent structure.

2.

Determine if sound is pure tone.

3.

Use appropriate measurement procedure described above.

4.

If possible, repeat procedure for different microphone locations.

I.

Officials trained in the enforcement of the Florida Motor Vehicle Noise Prevention and Control Act of 1974, Chapter 74-110, Laws of Florida, shall follow the procedure described in Department of Environmental Regulations Rules, Florida Administrative Code, Chapters 17-18, Vehicle Sound Measurement, Part I, Highway Vehicle Test Procedure to determine motor vehicle sound levels.

J.

The following shall be obtained and reported for each sound measurement period:

1.

Dimensioned sketch or photograph of the test area showing location of sound source(s) and receivers.

2.

Note any possible reflecting objects within test area.

3.

Physical and topographical description of the ground surface.
