Across
  1. 3. Space is an example of this as it doesn't have any particles
  2. 6. The maximum amount of vibration measured from the middle position of the wave in metres
  3. 9. Device able to view patterns of sound waves that have been turned into electrical signals
  4. 13. A type of wave with vibrations that occur parallel to the direction of the wave
  5. 14. This is the outer ear and directs the sound further into the ear
  6. 15. This is what waves transfer
  7. 16. When energy is transferred from sound to a material
  8. 17. A place where sound is produced from
  9. 18. Vibrations that pass as a wave using particles travelling faster through solids
  10. 19. The number of waves produced in one second in hertz
Down
  1. 1. Reflection of sound waves from a surface back to the listener
  2. 2. A place where sound waves are further apart
  3. 3. A back and forth motion that repeats
  4. 4. This is found inside the ear and transmits sound from the air into the middle ear and cochlea
  5. 5. A device that converts sound energy into electrical energy
  6. 7. Sound waves need these to transfer the sound waves (they don't have them in space)
  7. 8. A type of animal that uses echolocation to help hunt for its prey in the dark
  8. 10. This is found inside the ear and translates sound vibrations into nerve impulses
  9. 11. A place where sound waves are closer together
  10. 12. A device that converts electrical energy into sound energy
