Across
  1. 1. Maximum upward displacement; Max point of compression
  2. 4. 1. Sympathetic 2. Sounding Board and 3. Acoustic Resonance are examples of what type of vibration
  3. 5. Something that is set into vibration by the action of another vibration
  4. 8. The quantity of a three-dimnesional shape occupied by a liquid, solid, or gas
  5. 9. seconds/cycles
  6. 10. Unit that measures the intensity of a sound
  7. 12. Pressure Pressure above the atmospheric pressure
  8. 13. Positive pressure; molecules move close together
  9. 15. Disturbance of pressure that moves through a medium
  10. 17. Pressure Pressure below atmospheric pressure
  11. 19. Pressure Pressure at sea level
  12. 21. any influence that causes an object to undergo a change in speed, direction, or shape
  13. 22. Law Volume and pressure are inversely related
  14. 23. Lower pressure; molecules move farther apart
  15. 27. Wave changes direction due to an obstacle
  16. 28. Wave given their name due to the appearance that they are "stationary"
  17. 29. Frequency Lowest Frequency
  18. 30. Max. displacement from position of rest; Perception of loudness
  19. 32. Some portion of the sound wave that is not transmitted or absorbed bounces back from the surface of the boundary; traveling in opposite direction
  20. 33. a force that "acts perpendicularly on a surface"
  21. 34. Harmonic Motion A smooth back and forth motion
  22. 35. The kind of sounds periodic and aperiodic are
  23. 36. Decrease in amplitude
Down
  1. 1. Vibration occurring from a point of rest to max. displacement to rest to mac displacement; one compression and one rarefaction
  2. 2. Branch of physics concerned with the properties of sound
  3. 3. Wave changes direction because of a local difference of temperature in the air
  4. 4. Cycles/Seconds
  5. 6. In motion stays in motion; At rest stays at rest
  6. 7. A vibratory response to an applied force
  7. 11. Sound passes through something
  8. 14. What type of waves are used to visually represent simple harmonic motion or all the energy located at one frequency
  9. 16. 2 or more frequencies but the frequencies are not systematically related to each other
  10. 18. Lowest point in a cycle; Max point of rarefaction
  11. 20. Multiple reflections (echo)
  12. 24. refers to the amount of matter in an object
  13. 25. Distance from crest to crest or trough to trough
  14. 26. The property of an object to return to its original shape
  15. 30. Damping of a wave
  16. 31. Resonance also Acoustical Resonance
  17. 33. Consist of a series of frequencies that are systematically related to each other
  18. 34. To produce this you need an energy source, medium, vibrating body
