Full Breakdown
Section 311-8 governs sound production devices generally: no one may operate a device so that sound crossing a property line raises the total sound level above the neighborhood residual sound level by more than the limits in Table IV, measured inside a complainant's residence with the meter set to 'C' weighting and 'fast' response. , versus a 6 dB(C) increase at all other times, meaning the nighttime standard is roughly half the permitted daytime increase. m. Chapter 317's nuisance provisions widen that same public-space portable-speaker rule to 100 feet in both time windows under § 317-17B(4), so a device compliant with the Chapter 311 distance may still violate the Chapter 317 standard if Police measure it.
Violations & Fines
A Chapter 311 violation of § 311-8 or § 311-9F draws a notice of violation for a first, minor instance or a notice of penalty assessment for a nonminor or repeat instance, carrying a civil penalty up to $2,000 per offense under N.J.S.A. 40:49-5. A Chapter 317 citation under § 317-17B(4) carries the Chapter 1, § 1-2 general penalty of up to $2,000, 90 days' imprisonment, or 90 days of community service.
