I use one too, but it's clear that mp3 players require judicious use. The Irish Times reports on the European Union study showing that about 10% of people who use mp3 players for an hour a day risk their hearing. This is an excerpt:
Speaking during Hearing Awareness Week in January, Keith Ross, an audiologist with the Hidden Hearing clinic warned that young people were unaware of the fact that loud noise could cause irreparable damage.
"Noise-induced hearing loss is cumulative; it happens gradually over time so a young person will not know that they are doing damage. It's key that volume is kept relatively low ensuring they can still hear the sounds outside when wearing their earphones," he said.
