iPod headphones may damage hearing Music lovers are being warned that the popular 'earbud' headphones worn by users of iPods and MP3 players could lead to hearing loss. The warning comes from Dean Garstecki, a Northwestern University audiologist and professor, who said that because earbuds are placed directly into the ear, they can boost the sound signal by as much as six to nine decibels. "We're seeing the kind of hearing loss in younger people typically found in aging adults. Unfortunately, the earbuds preferred by music listeners are even more likely to cause hearing loss than the muff-type earphones that were associated with the older devices," Garstecki said. The audiologist claims that he has known students to listen to music at 110 to 120 decibels. "That's a sound level that's equivalent to the measures that are made at rock concerts," said Garstecki, "and it's enough to cause hearing loss after only about an hour and 15 minutes."
