City code section
- A. If measurements are made with a sound level meter, the meter must be an instrument in good operating condition, meeting the requirements of a Type I or Type II meter, as specified by ANSI Standard 1.4‑1971. For purposes of this Title, a sound level meter must contain at least an A‑weighted scale, and both fast and slow meter response capacity.
- B. If measurements are made with other instruments, the procedure must be carried out in such a manner that the overall accuracy must be at least that called for ANSI standard 1.4‑1971 for Type II instruments.
- C. When the location or distance prescribed in this Title for measurement of sound is impractical or would provide misleading or inaccurate results, measurements may be taken at other locations or distances using appropriate correction factors specified in this Title or in other rules promulgated by the City Administrator.
- D. Procedures and tests required by this Title and not specified herein will be placed on file with the City Auditor.
- E. For purposes of determining compliance with the measurable sound level requirements found in this Code, approved sound level meters must utilize a fast meter response setting. Slow sound level meter settings may not be used for the purpose of determining compliance with this Code, unless directed by the Noise Control Officer.
