24
Q

Steps sound takes to be registered in the human brain

A
  1. The auricle guides the sound down into the ear
  2. The sound goes through the auditory canal
  3. The ear drum vibrates and the vibrations get passed down to
  4. 3 bones in the ear vibrate more, and it gets passed down to the tympanic cavity which leads the sound to
  5. into the inner ear into the cochlea which transfers the sound into action potential
