Editor's Note: This ordinance replaces former Ch. 154, Noise, adopted 5-13-1996 by Ord. No. 355, as amended, was declared invalid by the State of Connecticut's Department of Environmental Protection because it was not reviewed by the DEP. This new ordinance was approved by the DEP in December 2003.

The general steps listed below shall be followed when preparing to take sound-level measurements:
(1) 
The instrument manufacturer's specific instructions for the preparation and use of the instrument shall be followed.
(2) 
The sound-level meter shall be calibrated before and after each set of measurements.
