Lowering the Volume

Turn that thing down! How often have you heard that request? Last week, Apple Computers, the makers of iPod MP3 players, released software that enables iPod users to limit the maximum volume on the devices. With the software, a parent can set a top volume on an iPod and lock it with a code.

IPods can produce a sound of more than 115 decibels, which is as loud as a chainsaw. "Any excessive sound level has the potential of causing hearing damage," says Jennifer Weber, a professor of audiology at the University of Northern Colorado.

"We want to offer customers an easy-to-use option to set their own personal volume limit," says Greg Joswiak, Apple's vice president of iPod marketing. The free software, which is available at apple.com, can be used only for the iPod Nano and iPods that have video capability.
