The plane noise will increase and have a heart attack probability
A new research reveals, living will increase the risk of dying of heart disease at the place where the plane often flies over, and noise volume loud, contact time long, high risk this.
The researchers of Switzerland Bern university pass and survey national death situation, find out from the end of 2000 to the end of 2005, in 4,600,000 Swiss residents in all parts of the country, because the detailed materials of 15532 people of the heart disease death, and the government records and helps them to fix with the environmental data, people these's house reaches in the distance between airport and primary highway.
After considering factors such as air pollution, level of education and income,etc., researchers find, volume and contact time size of the plane noise, have certain influence on the danger of heart attack of the mortality.
This research that is issued on the recent " epidemiology " periodical published claims, compared with contacting the person less than 45 decibels of noises, daily those are exposed to the persons of at least 60 decibels of noises of average level, the intersection of heart disease and danger of death its take 30% high. And contact those high noise already over 15 person of year, this dangerous to take 50% higher.
Study yet to find, those are fewer than the person 100 meters far from house to primary highway, also will increase the danger of heart attack. Researchers point out, this result of study is very obvious to the residents exposed to the high decibel of noises, and depend on how long people stay in noise environment.
Researchers propose setting up the sound insulation wall, controlling speed and traffic volume, and build the house with better sound insulation. (side keeps the people)
