Study Links Personal Music Players To Hearing Loss
fprintf writes "A recent NY Times article discusses links between personal music players and hearing loss. This is not anything new; personally, I have hearing loss from listening to my Sony Walkman cassette player many years ago. However, given the widespread use of the personal music players, I see people using earbuds everywhere; is there a technical solution to the potential danger?"
s there a technical solution to the potential danger ?
Yes - very technical. Turn down the volume.
What?
Light travels faster than sound. This is why some people appear bright until you hear them speak.........
I've noticed, many times, that I start out with a fairly low volume (maybe 10% or so), and when a good song comes along, I turn it up a bit. However, by the end of the song, I don't really notice the higher volume anymore, and the next time I get a good song, I turn it up a bit more, until the player is at its maximum volume.
If I take the earphones out of my ears, put them back in an hour later, and turn on the player, I'll pull them out of my ears as fast as I can because the music is so horribly loud.
So the solution, I think, is having a "volume boost" button, which boosts the volume for the duration of the current track, and gradually decreases to the normal level during the next track, to avoid stacking up the boosts.
All headphones are noise canceling if you listen to them long enough at max volume.

Does bone conduction cause the same problem? If not, Vibe Body Sound Headphones may be an answer.
There is no "-1 offended" or "-1 you don't agree with me" mod options for a reason.
The real problem is to determine whether you are playing the music too loudly for your safety. Here is how to get a good idea of the harm you are doing ...
1. Find something like a watch or other device that makes a very quiet sound. Find a distance where you can just make out the sound.
2. Listen to your music source at your customary level for 15 to 30 minutes or longer if that is your habit.
3. Set up the conditions in (1) above and see if you can still hear the sound. If you can, you are probably not harming your hearing ... If not, then you have a temporary threshold shift and you have already done some small amount of damage to your hearing. The greater the shift, the greater the damage.
4. More likely, if you listen to loud music or listen in inherently noisy places, you will notice the threshold shift in daily life. background noises disappear, which is like 40-50dB SPL, and definitely a problem.
These hearing conservation links explain a lot Mp3 players are not the only culprit, driving with wind noise in your left (or your passenger's right) ear, circular saws and construction tools, and other sources of noise are damaging. Music is different in that it can not be blocked but can be controlled.
If you don't protect your hearing from loud sound, sooner or later a notch will start to form in your ear's frequency response curve. The notch will be centered around 4000 Hz, right where high frequencies get really high, and useful too. That notch widens above and below until it impacts 2KHz or even lower. Somewhere along the way, the detectors in the ear will get so damaged that they start detecting sound non-linearly and harmonic and intermodulation distortion arise. Finally, when they get injured some more, they start to fire "all or none" and even moderately loud sounds can be painful. That is called recruitment and is really damaging to hearing and sanity.
I hope this information is useful to readers. I hate to see people lose hearing when it is so unnecessary in most cases.
If you think your hearing is going bad, see an audiologist or ear doctor or both, soon. Most processes can be stopped, and believe me, you will be glad you at least stopped the damage.
I am pushing 60 years old, have used threshold shift changes to remind me to protect my hearing, and still have no noise notch in my good ear. My other ear was damaged by childhood infections and is mostly useless so I guess having only one ear made me more careful.
