Exposure To Traffic Noise Leads To Higher Heart Attack Risk
2012-06-22 05:45:10

According to a study published in the journal PLoS ONE, exposure to traffic noise could lead to a higher risk of having a heart attack. A new study shows a clear relationship between traffic noise and heart attack risk, with a 12 percent higher risk per 10 decibels of noise. Previous work investigated whether combined effects of noise and air pollution caused by traffic could increase the risk of having a heart attack.  However, those results were inconsistent. The new study,...

A tuning fork, formed of a two-pronged fork, is an acoustic resonator with prongs formed from a U-shaped bar of elastic metal. When struck against a surface it resonates at a specific constant pitch emitting a pure musical tone after waiting a moment for some high overtones to die out. The length of the prongs determines the particular pitch of the fork. Most of the time it is used as a standard of pitch to tune other musical instruments. In 1711, John Shore invented the tuning fork. The...
