A new result of study by the Swiss Stockholm Kaluolinsika Research Institute publishes in "Epidemiology" magazine indicates: Comparing with people who live in quiet region , the people who live nearby the roads filling with traffic noises are easier to suffer from the myocardial infarction.

The research selected 1571 Stockholm residents who suffer from myocardial infarction from 1992 to 1994 as the objects of study. In order to confirm whether the traffic noises nearby the residential district have necessary connection with myocardial infarction, the researchers have carried on the evaluation of living environment and the noise level. Meanwhile, other pathogenic factors such as air pollutions are also taken into consideration in the design of questionnaire and interviews.

The researchers discovered that according to the overall data, there is no explicit relatedness between noise contact and myocardial infarction. However, after eliminating those crowds that had hearing impairment as well as those who contacted other noise source, the researchers found that the risk to suffer from myocardial infarction for people who expose for long in traffic sounds over 50 decibel is 40% higher than persons who live in the quiet environment. This conclusion is suitable for these existence situations such as the air pollution, etc other hazard factor.

Professor Golan Enger Persin, responsible for this research, said, "Stockholm Regional congress had considered that this achievement will be applied in the plan of newly built roads and residential districts. Our next step research will also make a more reasonable explanation to the connection between the traffic noise and myocardial infarction. But first we need to know the influence of noise to the cardiovascular system, like the relations between noise and hypertension."

The noise has already become an increasing serious environment problem. According to the World Health Organization statistics, there are nearly 40% Europe populations daytime expose in in road traffic noise over 55 decibels. In the traffic noise aspect, there is not any restrictive provision at present. Whereas in Switzerland, the maximum noise can be accepted is 55 decibels.
