Sound is read off the CD by a light(laser). It is transmitted by electricity through wires to the speaker in the ear phones( here it is transferred back to sound.) In the ear it causes the hais in the cochlea to vibrate and that transfers it through the auditory nerve to the brain.

It doesn't. CD players generate electrical signals which are transmitted through the wires to the ear buds, where the corresponding sounds are generated for the first time since they were encoded by the artist, at least for that particular play.

Look up the sound level and help people understand that is not only noise that will make u deaf. Music played too loud will do the same thing.
