"People whose homes were 'an inch' of the engine rumble, toot horns and brakes have sound that increases the risk for high blood pressure affected," said a study published Environmental Health, September edition that circulated in the United States.
To verify how much voice traffic that can be borne by the routine basis, the researchers from Lund University Hospital in Sweden analyzed data from nearly 28,000 people who asked about housing arrangements of people in Scandia, a province in southern Sweden.
They found that people who are young and middle-aged who lived at the house that exposure to noise of traffic above 60 decibels more likely to be stricken with high blood pressure, which in turn can cause strokes and blood vessel disease and heart.
Relationships with high blood pressure getting stronger as the decibel level rises.
Among older people, aged 60-90 years, the decibel level higher unrelated to high blood pressure.
One reason for these findings may be a younger person is less likely attacked by high blood pressure, so the impact of traffic noise more evident.
"The impact of noise may be not too important, or more difficult to detect, associated with other risk factors with age," said the study's authors, Theo Bodin. "The choice is probably a noise disturbance at the age of the human variety."
As many 30% of Europeans live in various areas where the average noise of traffic is 55 decibels or higher, the researchers said.
"The traffic on the road is the most important source of noise in the community," said Bodin.
