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