Question

Can you explain the hearing mechanism?

Answer 1

Hearing mechanism:

1. Hearing commences with the outer ear.
2. The sound reaches the outer ear, the sound waves or vibrations travel down the external auditory canal and can reach the tympanic membrane(eardrum).
3. The tympanic membrane vibrates. These vibrations reach the the three tiny bones in the middle ear called ossicles.
4. These ossicles amplify the sound. The sound waves then reach the inner ear to the fluid-filled hearing organ, cochlea.
5. On reaching the inner ear, the sound waves get converted to electric impulses.
6. These electric impulses are sent to the brain via auditory nerve.
7. The electric impulses get translated to sound by brain.

Hence we recognize the sound waves.
