People living in residential areas with high levels of noise from road traffic appear to suffer more heart attacks than people living in quieter neighborhoods, according to a new study by researchers at the Swedish medical university Karolinska Institute in Stockholm.
Goran Pershagen, who led the study, said 1571 people from the Stockholm area who had suffered heart attacks between 1992 and 1994 were compared with a control group from the same area. The addresses of all the individuals were indentified and the level of noise estimated.
Exposure to air pollution and other heart attack risk factors were also gathered using questionnaires and interviews, the researchers said. Once people with impaired hearing or exposure to other sources of noise had been eliminated from the study, the researchers found that there was a 40 percent higher risk of a heart attack in people exposed to traffic noise exceeding 50 decibels — a relatively quiet level of noise; heavy traffic is usually measured at between 80 and 90 decibels.
"More research will be needed to establish a definite correlation between road traffic noise and [heart attacks], but our results are supported by other studies showing the cardiovascular effects of noise," Pershagen said.

I had a neighbor that die of heart attack. If part of that could be attributed to noise we do not know. The true fact is that Traffic has got louder and way beyond its limits and cross property lines. I well know the stress I do have to go through every day and every weeked when the traffic just goes bust and what I can say is that if I did not have my wonderful friends I would be dead already.
Here some extra info as well. Thanks for posting

Noise pollution is just as bad as air pollution.
