(01/19/06) NEW BRUNSWICK ? Specialists in New Jersey fear the growing popularity of iPods and other portable MP3 players will translate into higher instances of hearing loss among residents.

Audiologists say the iPod?s volume level, along with its ability to play music for hours on end, could mean trouble for music lovers. Specialists say some iPods can reach volumes of 120 decibels, which is the equivalent of a person standing next to a jet engine. Experts claim many individuals won?t notice the hearing damage until it is too late.

Although some countries place volume restrictions on portable MP3 players, the U.S. does not. Audiologists suggest keeping the volume level to 60 percent or lower. They also say residents should listen to their iPods for no more than two hours a day.
