Working on the links between traffic noise and health, a new study has found that people exposed to louder traffic sounds run a greater risk of suffering a heart attack. By analysing more than 50,000 participants aged 50 to 64, Danish researchers discovered that the risk of a heart attack goes up by 12 percent for every 10-decibel increase of noise from traffic, pess TV reported.
To produce accurate results, the study was conducted in Copenhagen and Aarhus, two of the largest cities in Denmark, and kept track of many aspects of the participants' health for almost a decade.
