Edmund King said, "The findings of the Canadian study are bad news for decibel-loving drivers, as they prove that not only is loud music a nuisance to others, it could also be the cause of accidents on the roads." Drivers are at even greater risk if they listen to music with a pounding beat rather than more relaxed tunes, according to experts. Conrad King, consultant psychologist to the foundation, said, "It is important that drivers choose their music carefully when driving, as up-tempo music has been shown to cause drivers to have double the amount of accidents as those listening to slower music. In general, if music is above 60 beats per minute, listeners experience a faster heart rate and increased blood pressure. It doesn't matter if you listen to opera, classical or the latest rave music. It's the speed of the beat that counts."
