  • Sound waves can travel through solids causing vibrations in the solid
  • Within the ear, sound waves cause the ear drum and other parts to vibrate which causes the sensation of sound
  • The conversion of sound waves to vibrations of solids works over a limited frequency range so this restricts the limits of human hearing
  • The range of normal human hearing is from 20 Hz to 20 kHz
