The sound waves upon hitting the eardrum makes it to vibrate and the vibrations are passed on the ossicles of the middle ear. The sound waves are amplified by the ossicles and passes to the inner ear where it reaches the cochlea.

The sensory hair cells in the basilar membranes of the inner ear move the sound wave and also help to create electric signal which is received by the auditory nerves.

These signals are received by the brain where the sound waves are processed.

Then the study will be valid and effective as well.
