By the process of hearing, we can sense and react to the things that are happening in our surroundings. The steps that take place in this process are: Sound waves are received by the external ear.They are then directed to the eardrum.These waves then strike the tympanic membrane and there is compression and depression at the tympanic membrane and this tympanic membrane produces vibrations.From the ear ossicles, these are then transmitted. In the perilymph, a wave is set up by the movement of the oval window. Vibrations are caused to the endolymph of the scala media. In the basilar membrane, a wave is induced by the endolymph in the waves. The basilar movements help in bending the hair cells when they are pressed against the tectorial membrane. By the afferent neurons, new impulses are generated. They are then transmitted to the auditory region of the brain with the help of the auditory nerve.The impulse is then analyzed and the sound is then recognized.
