The current issue of Money magazine features connecting a review of noise-isolating earbuds to a topic that appears to be receiving more attention in recent months than it has in the past: noise-induced hearing loss. With the popularity of mp3 players, as well as the risk they present with improper use, some magazines are finding good reason to discuss the hearing factors involved in consumer-product reviews. “Easy Listening: Noise-isolating earbuds deliver music in peace, no matter what’s going on around you” by Wilson Rothman channels the main healthy hearing message using a consumer-friendly approach.
Rothman reviews six low-priced model earbuds and declares Creative’s Zen Aurvana, priced at $100, as the Field Test Winner. But before he names the winner, he notes the National Institute on Deafness and Other Communication Disorders ( www.nidcd.com), which states that exposure to sounds louder than 85 decibels for an extended period of time can cause hearing loss. He further mentions a significant detail that most consumers are unaware of: the maximum volume level on the iPod is 115 decibels. Rothman compares this sound level to a chain saw and grounded jet and provides an alternative to turning up your music to block background noise – buy a pair of decent noise-isolating earbuds to use with your mp3 player.
Although these are not “noise-canceling” headphones as Rothman points out, he covers all the essentials in his review of some brand-name noise-isolating earbuds and gives consumers a range to choose from. I use the Apple In-Ear earbuds and agree with Rothman that the price and sound quality are good but I think it has a couple drawbacks. My ear canals are fairly narrow and they fall out of my ear canal too often while exercising even though I use the appropriate size inserts. Without a nice tight fit, it is difficult to achieve its noise-isolating capacity.

Why not require manufacturers to mark the volume on these devices at 85 decibels?
That would be great but I don't think there is enough pressure on them right now. I think that it will happen in the future when the iPod generation suffers from early onset of hearing loss. Basically, when it's too late.
I will soon post about Apple's minor step in that directions. This is from their website.
