Listening to MP3 Players May Harm Hearing

Twenty-one young adults in Belgium with normal hearing were discovered to suffer significant deterioration in hearing at high and low frequencies after they listened to pop rock at comfortable levels for one hour. These changes were temporary but stayed consistent through 6 testing sessions using 2 types of headphones. More research is needed to evaluate the long-term risks.

PositiveTip: Keep the volume down when listening to your MP3 player to maintain hearing sensitivity.
