For the purpose of determining noise levels as set forth in this chapter, the following guidelines shall be applicable:
All personnel conducting sound measurements shall be trained in the current techniques and principles of sound measuring equipment and instrumentation.
Instruments used to determine sound level measurements shall conform to the sound level meters as defined by this chapter.
The general steps listed below shall be followed when preparing to take sound level measurements.
The instrument manufacturer's specific instructions for the preparation and use of the instrument shall be followed.
The sound level meter shall be calibrated before and after each set of measurements.
When measurements are taken out of doors, a wind screen shall be placed over the microphone of the sound level meter as per the manufacturer's instructions.
The sound level meter shall be placed at an angle to the sound source as specified by the manufacturer's instructions and at least four feet above the ground. It shall be so placed as not to be interfered with by individuals conducting the measurements.
Measurements shall be taken at a point that is located about one foot beyond the boundary of the emitter's premises within the receptor's premises. The emitter's premises includes his/her individual unit of land or group of contiguous parcels under the same ownership as indicated by public land records.
The recommended practices for determining statistical noise levels shall be those as outlined in the document entitled "Connecticut Noise Survey Data Form #101."
It shall be unlawful for any person to emit or cause to be emitted any noise beyond the boundaries of his/her premises in excess of the noise levels established in these regulations.
