The Commission is delegated by the New Jersey Department of Environmental Protection to enforce state noise control regulations (NJAC 7:29-1.1 et seq.). These regulations are designed to limit noise disturbances generated by fixed commercial and industrial sources. The regulations establish acceptable sound levels for both daytime (7 am to 10 pm) and nighttime (10 pm to 7 am) hours.
The Commission does not have jurisdiction over construction noise, intra-building noise, or residential noise sources (such as loud neighbors or boom boxes). These sources are not covered under the state noise code, and are generally left to municipalities to enforce pursuant to local ordinances.
