Full Breakdown
Article IV of Chapter 123 sets the Town's noise-district standards. Section 123-11 caps impulse noise, short bursts of high-intensity sound, at 80 dB peak sound-pressure level during nighttime hours (10:00 p.m. to 7:00 a.m. under § 123-6) in any Residential Noise District or Zone, and at 100 dB peak sound-pressure at any time in any noise district or zone. Section 123-13 then sets steady-state limits by emitter and receptor district. A source in a Residential Noise District cannot exceed 62 dBA reaching an Industrial Receptor, 55 dBA reaching a Business Receptor, 55 dBA reaching a Residential Receptor by day, or 45 dBA reaching a Residential Receptor at night; § 123-13C makes any level above those figures 'excessive and unnecessary noise.' Industrial and Business Noise Districts carry their own, generally higher, emitter tables in § 123-13A and B.
Section 123-14 allows a source to exceed background noise by up to five dBA without violating the chapter, capped at 80 dBA absolute, and § 123-15 permits short-term excursions of 3 to 8 dBA above the standard for limited minutes per hour. Noise districts track the underlying zoning classification under Chapter 177 per § 123-7.
Violations & Fines
The Director of Health enforces the decibel standards under § 123-20, using inspections, investigations or complaint-driven monitoring under § 123-22. A source measured above its applicable limit receives a written notice of violation under § 123-23 specifying the excess and a correction date; if reinspection shows noncompliance, § 123-24 imposes a fine of $20 to $90, with each day and night of continuing violation a separate offense, and no penalty accrues while an appeal under § 123-25 is pending.
