Question

How do we hear sound through the ear?

Answer 1

Ear:

1. The ear is a vertebrate organ of hearing and balance that, in most mammals, consists of an inner component that absorbs sound and sends nerve signals to the brain, as well as an outer section that gathers sound.
2. A sound produced by an item, such as a drum or an alarm clock, travels through the air and is heard by the ears.
3. Vibrations are how the sound is produced.
4. It first enters the ears through the outer, funnel-shaped portion of the ear.
5. It travels along a canal to get to the eardrum.
6. The tympanic membrane, or eardrum, is the middle ear's membrane that vibrates in reaction to sound waves.
7. The eardrum is necessary for the ears to operate properly.
8. The eardrum is the final destination of the items' vibrations, which travel through the atmosphere.
9. The eardrum vibrates as a result of these vibrations.
10. The middle ear bones, or ossicles, then convey the vibrations to the inner ear.
11. The cochlea, the inner ear, is shaped like a snail.
12. The cochlea is the spiral-shaped inner ear cavity that houses the organ of Corti, which generates nerve impulses in response to vibrations of sound.
13. There are countless little hair cells inside the cochlea.
14. These hair cells transform the vibrations into electrical signals, which are then transmitted to the brain via the auditory nerve.
15. We distinguish between sound and noise in this way.
16. Our bodies transform sound energy into nerve impulses by our bodies, which our brains then decode.
17. Each hair cell's top is connected to small stereocilia.
18. Sound causes the stereocilia to sway back and forth.
19. The stereocilia may be bent or fractured if the sound is powerful.
20. This might cause hair cells to die, which would prevent sound from reaching the brain.

The process through which sound is perceived by the ears is shown in the flowchart below:
