7. Loudspeaker deviation from a flat frequency response should be no greater than: (p. 172)

a. plus or minus 3 dB
b. plus or minus 6 dB
c. plus or minus 9 dB
d. plus or minus 12 dB

8. If a 50-watt power amplifier is replaced with a 100-watt power amplifier, the resulting sound will be: (p. 72)

a. slightly louder
b. the same loudness
c. twice as loud
d. four times as loud

9.Distortion is the: (p. 172)

a. lowering of maximum output level
b. result of using a single loudspeaker for monitoring
c. result of not using noise reduction

10. Intermodulation distortion results when: (p. 172)

a. sound is played too loud
b. two frequencies interact to produce other tones
c. the signal changes too rapidly
d. an amplifier with too little power is used

11. By comparing the sensitivity rating of different loudspeakers, it is possible to tell which loudspeaker: (p. 173)

a. will play loudest
b. will produce the least harmonic distortion
c. has the least loudness distortion
d. produces the most output for a certain amount of power

12. The considerations related to how a loudspeaker focuses sound at the monitoring position(s) are: (p. 173)

a. output level capability and wattage
b. sensitivity and arrival time
c. monitor placement and phasing

a. more direct sound
b. more indirect sound
c. a better spectrally balanced sound
d. less bass

15. Near-field monitoring reduces the audibility of control room acoustics by placing loudspeakers close to the listening position. (p.179)

a. true
b. false

16. A real-time analyzer is used to analyze: (p. 183)

a. acoustic time delay in real time
b. time delay in the reverb system
c. frequency response in real time
d. loudspeaker response in real time

17. One of the following is not an advantage of monitoring with headphones in a control room: (p. 185)

a. sound quality will be consistent in different studios
b. subtle changes in a recording are easier to hear
c. the aural image is inside the head rather than out in front
