Some have claimed lately that portable music players are causing hearing problems because people listen at high volume for long periods of time.
Apple announced Wednesday a software update for the iPod nano and fifth generation iPod that allows customers to easily set a maximum volume. The software update also gives parents the ability to set a maximum volume limit and lock it with a combination code, the company said in a news release.
The software is available as a free download from Apple."
