Pretty soon everyone on the planet will have an iPod. My buddy John Hawbaker of Clarity (part of Plantronics) pointed out this study to me. It’s probably a good thing to read for iPod owners. I have significant hearing loss in one ear (not because of an iPod), and it’s a pain in the ass, so I’d like to help people avoid hearing loss if possible.

Sound Output Levels of the iPod and Other MP3 Players: Is There Potential Risk to Hearing?
