Answer -
Sound servers as stimulus for auditory sensation. Loudness, pitch, and timbre are the тАУ properties of sound. Organ of corti located in the basilar membrane is the chief organ of hearing.
Auditory sensation begins when sound enters our ear and stimulates the chief organs of hearing.
Pinna collects the sound vibration and serve them to the tympanum through the auditory meat us.
From the timpani cavity the vibrations are transferred to the three ossicles, which increase their strength and transmit them to the inner ear. In the inner ear the cochlea receives the sound waves.
Through vibrations the endolymph is set in motion, which alsor vibrate the organ corti. Finally the impulses are sent to the auditory nerve, which emerges at the base of cochlea and reaches the auditory cortex where the impulse is interpreted.
