Found out about how the ears work, but cannot link back to your
question.
Sound waves are first collected in our outer ear (called the
auricle or pinna), pass through our ear canal and cause our eardrum
to vibrate. These vibrations are in turn transmitted to our inner
ear by the bones of our middle ear. Our inner ear plays a vital
role in the transformation of these mechanical vibrations into
electrical impulses, or signals, which can be recognized and
decoded by our brain. When the vibrations reach the cochlea through
movement of the bones in the middle ear, the fluid within it begins
to move, resulting in back and forth motion of tiny hairs (sensory
receptors) lining the cochlea. This motion results in the hair
cells sending a signal along the auditory nerve to the brain. Our
brain receives these impulses in its hearing centers and interprets
them as a type of sound.
Not quite sure, but I think is this:
Due to the difference in pressure, it causes changes in the fluid
within the middle ear. The changes in fluid probably cause the
giddiness in us.
