How you hear?

How you hear?

Ever wonder how we can hear voices and sound around us?

The diagram illustrated below will give you a brief introduction on how we can hear.

  1. The bowl or concha captures vibrations in the air.
  2. The sounds are carried through the outer auditory passage.
  3. The ear drum vibrates and passes the sound into the middle ear.
  4. The tiny bones in the middle ear transmit vibrations to the inner ear.
  5. The bony labyrinth and cochlea convert vibrations into nerve impulses via tiny hair cells.
  6. The auditory nerve transmits these impulses to the brain for recognition.
