Hearing is complex, requiring a series of actions and reactions to work. The process involves many parts of the ear working together to convert sound waves into information the brain understands and interprets as sounds.
- Sound waves enter the ear canal and travel toward our eardrums.
- These sound waves cause the eardrum and bones in the middle ear to vibrate.
- Tiny hair cells inside cochlea (inner ear) convert these vibrations into electric impulses/signals that are picked up by the auditory nerve.
- The ear has over 25,000 tiny hair cells to hear varying degrees of sound.
- Signals sent to the brain from auditory nerve are then interpreted as sounds.
