In previous studies, aircraft noise was associated with an increased risk for hypertension, but few studies have addressed the association of aircraft noise with cardiovascular disease or mortality, partly because a very large exposed population is needed to provide adequate statistical power. In two new reports, researchers tackle this issue.
In the U.K., investigators studied annual exposure to aircraft noise levels and rates of hospital admissions and death from stroke, coronary heart disease, and cardiovascular disease from 2001 through 2005 in 3.6 million U.K. residents living near Heathrow airport.
