The sound of the CD is read by laser light (). It transfers power from the son in the ear speaker device (which will be returned to the music.) In fact, shark's ear into the cochlea to vibrate, and the transfer of the ear nerve to the brain.

Locate the sound level and help people to understand that this is not just the sound that make you deaf, or. Loud music will do the same.

Not so. CD players produce electrical signals that are transmitted by the son on the headset, the sounds are, for the first time since they were created by the artist consolidated, at least for this work.
