Wired reports the fear of researchers with the dramatically increasing number of hearing loss in younger people. It is directly linked to the increased popularity of MP3 players, iPods, mobile phones and other portable music players.
Hearing specialists detect already problems with 30 and 40 years old people (the walkman generation).
The problem is not only due to the volume but also how long people listen to music, and the constant improvement of rechargeable battery lifespan might also contribute negatively to the hearing problem. Ears need some rest.
But this is also true for people going to concert where the usual music level is far beyond the safe listening limits
In France, music players are limited to a 100dB audio output limit, and even 80dB for children-dedicated devices. This is something positive, but it will not prevent you to damage your eras if you keep your iPod playing for 10 hours a day.
