What will be an ideal response?
The vibrations of the sound waves cause the eardrum to move. This in turn causes the ossicles to transfer the vibration to the oval window of the cochlea. The oval window transfers the motion to the fluid in the cochlea. The motion of the fluid stimulates the small hairlike nerves that transmit the signal to the brain through the auditory nerve.
