Hearing

• Our ears allow us to understand sounds.
• The external ear captures sound, while the
  internal portion processes it.

Hearing

• Tiny bones in the ear create vibrations in fluid.
• These ripples are detected by delicate hairs, and
  signals are sent to the brain.

11
Hearing

• The ears also contain vestibular organs that give
  us our sense of balance.
• When these get messed up, you become dizzy (think
  of car sickness!)
