Exposure to high levels of aircraft noise is associated with an increased risk of cardiovascular disease, studies from the United Kingdom and United States published in the BMJ have found.

In the first study UK researchers compared hospital admissions and death rates for stroke, coronary heart disease, and cardiovascular disease from 2001 to 2005 in 12 London boroughs and nine districts west of London. These areas, which are home to 3.6 million people, experienced annual average daytime noise levels of at least 50 dB from Heathrow in 2001.

The researchers found that in areas with the highest levels of daytime noise (>63 dB) the risk of hospital admission was 20% to 30% higher than in areas with the lowest noise (≤51 dB) for stroke (relative risk 1.24 (95% confidence interval 1.08 to 1.43)), coronary heart …
