Failure to cease operation within two days of notice to do so by the City constitutes an aggravated violation of this Ordinance and the penalty provision cited in Section 13 may be imposed I. TECHNICAL PROVISIONS 1. Noise a. To measure the intensity and frequently of sound, the sound level meter, the octave band analyzer, and the impact noise analyzer may be employed. The flat network and the fast meter response of the sound level meter may be used. Sounds of short duration that cannot be measured accurately with the sound level meter may be measured with the impact noise analyzer. Octave band analyzer calibrated in the preferred frequencies (American Standards Association S1 6-1960, Preferred Frequencies for Acoustical Measurements) may be used with the following tables. Should a complaint be filed with the City regarding industrial use noise, the suspected violator must hire a consultant approved by the City to measure, record, and report to the City results of the analysis. The alleged violator will pay all costs of testing. b.
