Sound Waves

• They are caused by vibrating objects
• Hearing Sound

  • Sound waves that reach your ear drum can cause it to vibrate
  • These vibrations are passed onto tiny bones in your ear
  • The cochlea turn these vibrations into electrical signals which get sent to your brain and allow you to sense sound
  • Hearing is limited by the size and shape of the our ear drum, as well as the structure of all the parts within the ear that vibrate
• Sound waves

  • Can be reflected by hard flat surfaces
  • Sound waves will be refracted as they enter different materials
