The basilar membrane has the function to know pitch. The mebrane is stiff and narrow at the beginnening but flexibel at the end.
  • High pitches= maximum displacement at the beginning of the membrane
  • Low pitches= maximum displacement at the end f the membrane
  • Higher grades + faster learning
  • Never study anything twice
  • 100% sure, 100% understanding
