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