This is junk science because…
The reported correlation (a 3.5% increase in heart disease risk per 10 decible increase higher aircraft noise — whatever that means) is too small to measure with any confidence whatsoever. Heart disease is naturally occurring and multifactorial, and incapable of being studied via weak association epidemiology.
The CBC reported:
Living in neighbourhoods with high levels of aircraft noise is associated with a higher risk of cardiovascular disease, U.S. and British research suggests.
Two studies published in Wednesday’s British Medical Journal offered “preliminary evidence that aircraft noise exposure is not just a cause of annoyance, sleep disturbance and reduced quality of life but may also increase morbidity and mortality from cardiovascular disease,” an accompanying editorial said.
In one study, Francesca Dominici’s team at Harvard School of Public Health in Boston found a higher rate of admission to hospital with cardiovascular problems among people aged 65 and older living near 89 airports in the U.S. in 2009.
On average, zip codes with 10 decibel higher aircraft noise had a 3.5 per cent higher cardiovascular hospital admission rate. The association remained after taking socioeconomic status, demographic factors, air pollution proximity to roadways into account in the analysis.
