I have a hearing loss and was wondering how much the brain is involved in
interpretating what a person hears through hearing aids. If the brain is actually hearing and is transmitted through the ears then a hearing loss is a loss of
something in the brain?

It all depends on why you have hearing loss. First of all, this mechanism, the mechanism of hearing is pretty simple to understand. This is how this mechanism works:
Sound waves enter the outer ear and travel through the external auditory canal until they reach the tympanic membrane, causing the membrane and the attached chain of auditory ossicles to vibrate.

The motion of the stapes against the oval window sets up waves in the fluids of the cochlea, causing the basilar membrane to vibrate. This stimulates the sensory cells of the organ of Corti, atop the basilar membrane, to send nerve impulses to the brain.

If all that mechanical parts are working well, then it could be a brain problem. If that is the case, email me at drchasegawa@gmail.com and I can tell you about that part.
