  1. 3. The change of pitch when a sound source is moving in relation to an observer.
  2. 9. The study of how sound interacts with structures.
  3. 11. The highest frequency at which a material vibrates.
  4. 14. _______________ is the transfer of energy by a wave to the medium through which it travels.
  5. 15. An acronym for Sound Navigation and Ranging. It is also used by ships.
  6. 17. ________ can affect sound speed because the particles are packed tightly together and collide to transfer energy quickly.
  7. 20. The amount of energy that passes through a square meter of space in one second is the _______.
  8. 21. _____________ is the movement of sound through a medium.
  9. 23. _______ is how closely particles are packed and can affect the speed of sound waves.
  10. 24. ____________ occurs when waves that overlap combine, forming a new wave.
  11. 25. Sound waves carry __________ away from the source as the particles in a medium vibrate.
  12. 27. A region of a longitudinal wave where the particles in a medium are closest together.
  13. 28. A ________ is the distance between a point on one wave and the nearest point just like it.
  14. 29. The lowest frequency at which a material naturally vibrates.

  1. 1. The intensity and amplitude of a sound wave affects its _________.
  2. 2. The bouncing of a wave off a surface.
  3. 4. Many animal, such as bats, use this to communicate.
  4. 5. The number of wavelengths that pass by a point each second.
  5. 6. The perception of how high or low a sound seems.
  6. 7. An __________ is a reflected sound wave.
  7. 8. Longitudinal waves that can only travel through matter.
  8. 10. ___________ has many uses, and can be used in the medical field to help treat certain problems.
  9. 12. A region of a longitudinal wave where the particles are farthest apart.
  10. 13. The maximum distance the particles in a medium move from their rest positions as the wave passes through the medium.
  11. 16. A rapid back-and-forth motion that can occur in solids, liquids, or gases.
  12. 18. A material in which a wave travels.
  13. 19. As the __________ of a gas increases, the particles move faster and collide more often, making sound waves move faster.
  14. 22. The collection of reflected sounds from the surfaces in a closed space.
  15. 23. The unit of measurement that describes the intensity or loudness of sound.
  16. 26. __________ is an increase in amplitude that occurs when an object vibrating at its natural frequency absorbs energy from a nearby object vibrating at the same frequency.
