I saw this on the news last night. Thats scarey.
Yes it is scary. The medical blogosphere is alight with this study today.
I'm not surprised. I did a recent survey for a hit and run member just recently.
To conserve battery life these ear buds and phones for on the move devices are getting more and more efficient.
I found one set that could achieve 120 db at the ears with just 120 MW.
The max power available from most of those devices is a little over 300 MW. Most can achieve 120 db at the ear with less power than this. So you can draw your own conclusions.
Headphones are tricky, because you get no sound back from the room, which is a big cue to loudness.
You get in your own isolated space with phones and it is easy to misjudge the spl. at your ears. So educating for this will be hard.
It seems to me it requires a technical solution of some type.
I'm afraid by mid life we are going to have a harvest of profoundly deaf individuals. I hate to even think about old age.
The worst of it is once the damage starts, even if they turn it down at the first sign, neural hearing loss will be progressive.
This is very bad but not unexpected news.
Before more formal steps can be taken a study will have to correlate the frequency and degree of hearing loss with these portable devices.
