What? What did you say? I can’t hear ya? Can ya speak a little louder there?
Usually you hear these sorts of questions in nursing homes or from your parents once they’ve gone gray and wrinkly.
Recent study shows that mp3 players can increase the risk of hearing loss. Happy listening! :nahnah:
Here is the exerpt from an NYTimes article:

The component that can have the greatest impact is the headphone. In a study published last year in the journal Ear and Hearing, Dr. Brian Fligor of Harvard Medical School looked at a variety of headphones and found that, on average, the smaller they were the higher their output levels at any given volume control setting.
Compared with larger headphones that cover the entire ear, some insertable headphones, like the white ones sold with iPods, increased sound levels by up to nine decibels. That may not seem like much, but because decibels are measured in logarithmic units, it can mean the difference between the noise output of an alarm clock (about 80 decibels) and that of a lawnmower (about 90 decibels).
The other problem, a second study found, is that insertable headphones are not as efficient at blocking background noise as some larger ones that cover the ear, so there is more incentive to turn up the volume.**
