Goran Pershagen, a cardiologist from the Karolinska Institute (Sweden) and colleagues studied 1,571 people who had suffered a heart attack between 1992 and 1994. After knowing the address of each patient, the research team came. take place to measure noise levels. In addition, experts also asked patients to provide information about the frequency of exposure to air pollution, smoking and some other factors related to heart disease. People with ear problems (deaf, hard of hearing) or frequently exposed to noise types that are not related to traffic are immediately removed.

The team found that people who often heard traffic noise greater than 50 decibels had a 40% higher risk of heart attack than people living in areas with a sound intensity of less than 50 decibels. Meanwhile, the noise on the busiest roads is usually in the range of 80-90 decibels.

'We need more research to verify the relationship between traffic noise and heart disease, but our findings are consistent with previous studies on the impact of noise on heart health. ' Goran said.

According to Goran, urban planners and transporters should consider the relationship between noise and heart attack when building residential areas and roads.
