headphones (“earbuds”) like those sold with the iPod and other music players can increase the risk of hearing loss, according to a US audiologist .
Research undertaken by Dean Garstecki of Northwestern University has found that that an increasing number of young people were now experiencing the kind of hearing loss found in aging adults.
According to Garstecki, cheap earbud headphones were more likely to increase the risk of hearing loss than old-school ‘over the ear’ headphones like the Grado SR60.headphones (“earbuds”) like those sold with the iPod and other music players can increase the risk of hearing loss, according to a US audiologist .
Research undertaken by Dean Garstecki of Northwestern University has found that that an increasing number of young people were now experiencing the kind of hearing loss found in aging adults.
Garstecki’s studies found that MP3 users often crank the volume up to 110 to 120 decibels – enough to cause hearing loss after about an hour of listening.
The problem is worse for earbud wearers because the sound source is placed directly into the ear, boosting the sound signal by as much as six to nine decibels – the difference in intensity between the sound made by a vacuum cleaner and the sound of a motorcycle engine according to Garstecki.
