PN Restaurants -3- 3 February 2025 3.0 REQUIREMENTS OF THE APPLICABLE NOISE REGULATIONS The New Jersey Department of Environmental Protection (NJDEP) maintains a statewide noise regulation, and the Township of West Orange code also includes regulations regarding sound. 3.1 NJDEP Noise Regulation The NJDEP noise regulation is set forth in N.J.A.C. 7:29 and limits the A-weighted sound levels produced by a commercial facility, when measured at a residential property line, to the following sound levels. Daytime (7:00 A.M. -to- 10:00 P.M.) – 65 dB(A) Nighttime (10:00 P.M. -to- 7:00 A.M.) – 50 dB(A) When the sound from the source is constant in level and in character, the NJDEP regulation also provides limits for sound pressure levels in the preferred octave bands with center frequencies between 31.5 and 8000 Hz, as summarized in Table 1. Table 1 – Daytime and Nighttime Sound Pressure Level Limits [dB re: 20Pa] of the NJDEP Noise Regulation for Residential Property Receivers (N.J.A.C. 7:29) Octave Band Center Frequency, Hz 31.5 63 125 250 500 1000 2000 4000 8000 Daytime Limits 96 82 74 67 63 60 57 55 53 Nighttime Limits 86 71 61 53 48 45 42 40 38 For commercial receiving property lines, the limits are the same as the daytime limits listed above and are applicable 24 hours a day. 3.2 Township of West Orange Noise Regulation The local noise regulation is set forth in Chapter 4 of the Code of the Township of West Orange. Section 4-4 (Noise) provides language that subjectively prohibits “excessively loud and disturbing noise which injures or endangers the health, comfort or safety of others within the limits of the Township.” As the local noise regulation does not provide any quantitative sound level limits, the results of the evaluation were evaluated with respect to the NJDEP noise regulation.
