The ear has 3 main parts. First is the outer ear which includes the outer ear canal (the portion u stick a qtip in). Then there is the middle ear which includes the eardrum and the 3 tiny ear bones, called ossicles. The third portion is the inner ear which contains the cochlea and nerves.
Ok- now to get to the main bulk of your question: when you listen to loud music, tiny hair cells in the cochlea of the inner ear are damaged, causing permanant hearing loss. The eardrum is not damaged. However, it is possible for it to burst as a result of infection– but not loud sound. So these tiny hair cells located I the cochlea of the inner ear are supposed to be flexible and loud sounds damage them by stiffening them.
That is a very simple way of explaining it… But I know a lot about this and can give more info or details or explain it differently if needed. Good luck.
