Traffic noise may cause heart attack: Study

Copenhagen : Exposure to traffic noise could cause heart attacks, says a new study.

A previous work had investigated the combined effects of both noise and air pollution caused by traffic on the heart, but the results were inconsistent.

The new study, led by Mette Sorensen of the Danish Cancer Society, showed a clear relationship between traffic noise and heart attack – a 12 percent higher risk per 10 decibels of noise among 50,614 study participants, the journal Public Library of Science ONE reports.
