Are you living near the highway with lots traffic noises? Well, researchers found out that the amount of traffic noise to which you are exposed increases the risk of heart attack. Researchers said that the increase in risk – though slight – is greatest with road and rail traffic noise, less with aircraft noise. Andreas Seidler from Germany’s Dresden University of Technology and his co-authors evaluated information for the study from statutory health insurers on over a million Germans over the age of 40.In this case-control study of secondary data, the addresses of persons living in the Rhine-Main region were matched precisely to road, rail, and traffic noise exposure measurements for 2005.When the analysis was restricted to patients who died of heart attack up to 2014/2015, a statistically significant association was found between noise exposure and the risk of heart attack. The authors believe the lower risk from aircraft noise can be explained by the fact that, unlike road and rail traffic noise, aircraft noise never remains continuously above 65 dB (decibel).
