More on Environmental Noise (02-06-18)

New research indicates how important it is to block the flow of environmental sound (from aircraft, trucks, trains, etc.) into buildings and to reduce outside noise levels via traffic routing/management, building orientation, etc.  Munzel and his team report that “Noise has been found associated with annoyance, stress, sleep disturbance, and impaired cognitive performance. . . . studies have found that environmental noise is associated with an increased incidence of arterial hypertension, myocardial infarction, heart failure, and stroke. . . . especially nighttime noise increases levels of stress hormones and vascular oxidative stress, which may lead to endothelial dysfunction and arterial hypertension.”  The Munzel lead group share that environmental noise is stressful and that it affects human bodies at a cellular level.
