MP3 Players Associated with Short-Term Hearing Loss

Listening to an MP3 player for just an hour can lead to temporary hearing loss, according to a small study in the Archives of Otolaryngology—Head & Neck Surgery.
Researchers in Belgium had 21 young adults with normal hearing listen to pop rock on an MP3 player at comfortable volumes for an hour, on six different occasions at least 2 days apart. The researchers found that, after listening, subjects experienced significant deterioration in hearing at high and low frequencies. Analyses revealed that hearing loss was temporary — participants recovered their normal hearing in between listening sessions.
The authors call for more research but say their findings "indicate the potential harmful effects" of listening to MP3 players.
