Negative Consequences of Noise On Overall Health

Oct. 29, 2013 — The combined toll of occupational, recreational and environmental noise exposure poses a serious public health threat going far beyond hearing damage, according to an international team of researchers writing today in The Lancet. The review team, including a Perelman School of Medicine at the University of Pennsylvania expert, examined the latest research on noise's impact on an array of health indicators -- hearing loss, cardiovascular disease, cognitive performance and mental health, and sleep disturbance -- in order to inform the medical community and lay public about the burden of both auditory and non-auditory effects of noise.

Relating to non-auditory effects, the authors conclude that because of the ubiquitous exposure of environmental and social noise, its public health effect is easily underestimated. According to the World Health Organization (WHO), more than one million disability adjusted life years are lost in western European member states alone due to environmental noise exposure, most of these caused by sleep disturbance and community annoyance.

Accordingly, the authors found evidence that long-term exposure to environmental noise affects the cardiovascular system, with connections to hypertension, ischemic heart diseases, and stroke. In addition, numerous studies pointed to associations between environmental noise exposure and sleep disturbance, children's cognition, and negative effects in hospitals for both patients and staff.
