How the ear works

  1. Any source of sound sends vibrations or sound waves into the air.
  2. These funnel through the ear opening, down the external ear canal, and strike your eardrum, causing it to vibrate.
  3. The vibrations are passed to the three small bones of the middle ear, which transmit them to the cochlea.
  4. The cochlea contains tubes filled with fluid. Inside one of the tubes, tiny hair cells pick up the vibrations and convert them into nerve impulses.
  5. These impulses are delivered to the brain via the hearing nerve.
  6. The brain interprets the impulses as sound (music, voice, a car horn, etc.).
