Noise health effects are the physical and psychological health consequences of regular exposure, to consistent elevated sound levels. Elevated workplace or environmental noise can cause hearing impairment, hypertension, ischemic heart disease, annoyance, and sleep disturbance. Changes in the immune system and birth defects have been also attributed to noise exposure.[1]
Although presbycusis occur naturally with age,[2] in many countries the cumulative impact of noise is sufficient to impair the hearing of a large fraction of the population over the course of a lifetime.[3][4] Noise exposure has been known to induce tinnitus, hypertension, vasoconstriction, and other cardiovascular adverse effects.[5] Chronic noise exposure has been associated with sleep disturbances and increased incidence of diabetes. Adverse cardiovascular effects occur from chronic exposure to noise due to the sympathetic nervous system's inability to habituate. The sympathetic nervous system maintains lighter stages of sleep when the body is exposed to noise, which does not allow blood pressure to follow the normal rise and fall cycle of an undisturbed circadian rhythm.[6]
Stress from time spent around elevated noise levels has been linked with increased workplace accident rates and aggression and other anti-social behaviors.[7] The most significant sources vehicles, aircraft, prolonged exposure to loud music, and industrial noise.[8]
