1. The middle ear is
"mechanical" (basically three bones passing sound
waves to the inner ear)
and its workings can be blocked by gunk.
2. The inner ear takes
these sound waves and pass them along fluid,
inside the spiral shaped
cochlear. Tiny hairs convert these movement to
electric impulses and fire to the brain. So the inner ear is
"neural" . The inner ear also has "semi circular canals"
which control balance. So inner ear trouble typical involves both hearing and balance
issues.
