For the “hip and happening” set – it might be “cool” to listen to music on an iPod or MP3 player, with ear buds plugged directly into the ears But Dean Garstecki, a Northwestern University audiologist, warns that these ear buds might increase the risk of hearing loss.

Garstecki says that ear buds associated with modern devices the likes of iPods, MP3 players, etc, boost sound signals by as much as 6 to 9 decibels, and are likely to result in loss of hearing.

According to Garstecki, an increasing number of young people are now experiencing the kind of hearing loss found in aging adults, which can be traced back to their music habits.

Students are found to listen to music at nearly 110 to 120 decibels, capable of causing hearing loss after just about an hour of listening; with ear buds placed directly in the ears, adding to the damage caused.

As solution to the problem, Garstecki recommends use of muff-type ear phones associated with older devices, as against the ear buds preferred by music fans today. He also suggests lowering of volume levels while listening to music. Another option is to use noise-cancelling headphones, which eliminate background noise unlike ear buds.

But Garstecki says that these headphones by virtue of their higher cost and larger size, may not go down very well with fashion-conscious youngsters.
