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 instruction.
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 the 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.
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.
Noise level standards:
No person in a residential zone shall emit noise beyond the boundaries of his/her premises exceeding the levels stated herein and applicable to adjacent residential, commercial and industrial zones:
No person in a commercial zone shall emit noise beyond the boundary of his/her premises exceeding the levels stated herein and applicable to adjacent residential, commercial or industrial zones:
No person in an industrial zone shall emit noise beyond the boundary of his/her premises exceeding the levels stated herein and applicable to adjacent residential, commercial or industrial zones:
High background noise levels and impulse noise.
In those individual cases where the background noise levels caused by sources not subject to these regulations exceed the standards contained herein, a source shall be considered to cause excessive noise if the noise emitted by such source exceeds the background noise levels by five (5) dBA, provided that no source subject to the provisions of this chapter shall emit noise in excess of 80 dBA at any time, and provided that this section does not decrease the permissible levels of other sections of this chapter.
No person shall cause or allow the emission of impulse noise in excess of 80 dB peak sound pressure level during the nighttime to any residential noise zone.

For the purpose of determining compliance with the provisions of this chapter, the Board of Selectmen or its designated representative is hereby authorized to make inspections of all noise sources and to take measurements and make tests whenever necessary to determine the quantity and character of noise. In the event that any person refuses or restricts entry and free access to any part of a premises or refuses inspection, testing or noise measurement of any activity, device, facility or process where inspection is sought, the Board of Selectmen or its designated representative may seek from the appropriate court a warrant without interference, restriction or obstruction, at a reasonable time, for the purpose of inspecting, testing or measuring noise.

Compliance with the regulations constitutes an unreasonable hardship on the applicant.
The application for variance shall be reviewed and either approved or rejected at least five days prior to the proposed start of said activity. The approval or rejection shall be in writing and shall state the condition of approval, if any, or the reasons for rejection.
