Noise Control Program
“In 1974, the EPA estimated that nearly 100 million Americans lived in areas where the daily average noise levels exceeded its identified safe Day-Night Level of 55 dB (EPA, 1974). In 1990, that estimate had risen to 138 million people”. (Eldred, 1990)
Unregulated sources of noise can have impacts far beyond the obvious transitory nuisance, and complainants may be enduring more than simple annoyance. Exposure to loud noise has been shown to result in uncontrollable stress which can result in alterations in moods as well as hormonal and nervous system changes in healthy subjects (Brier, 1987). A lack of control over noise results in a variety of neurobiological and behavioral alterations, a phenomenon known as “learned helplessness” (Brier, 1987). It has been demonstrated that blood pressure is reproducibly elevated in response to intermittent loud noise (Sawada, 1993).
The noxious stimulus of noise has long been used as a laboratory model for producing stress because it results in the same biological and physiological responses as other stressors (Suter, 1992). Noise has been clearly implicated in sleep disturbance (Lukas, 1977), resulting in a cascade of negative effects (Suter, 1992). The stress, tension and fatigue associated with long-term exposure to noise has destroyed marriages, cost people their jobs and forced other people to sell their houses at significant losses (RNTAC, 1991-2002).” *
Noise Regulations in New Jersey are designed to limit noise disturbances generated by fixed Commercial and Industrial facilities and a variety of other activities, as enumerated in NJAC 7:29.
The Commission investigates complaints of noise disturbances on a 24 hour/day basis.
