Decibel Amplitude 0 1 20 100 60 10000 120 1,000,000 4. On the decibel scale, a "quiet whisper 1 meter away" is about decibels, where a "jackhammer 3 meters away" is decibels. a) 20, 100 b) 10, 100 c) 10-15, 90 5. is the science and technology of sound. 6. The speed of sound is miles/hr, which is slower than the speed of light at miles/sec. 7. What does it mean when we say something is "supersonic?" 8. What is a sonic boom? 9. How fast does sound travel through different materials? 10. The Doppler effect is a shift in the of an oscillation caused by the motion of the source of the oscillation, and occurs at speeds below the speed of sound. a) amplitude b) frequency c) speed 11. Describe how observers "A" and "C" hear the moving sound in the picture in the middle of page 581. 12. Draw a "flow chart" that shows how the process of recording sound occurs.
