How does an AV system designer estimate the needed frequency response of an audio system?

The frequency response should be depending on the sort of applications the audio is designed to serve.

The audio system output frequency response should correspond to the frequency response of the audio source components.

The designer should strive to produce as broad a frequency response as feasible given the project budget.

The audio system's frequency response should be within the industry standard of 20Hz to 20kHz.

Correct! Wrong!

The sound energy of a loudspeaker, for example, decreases as the listener travels away from it. Which formula would you use to calculate the decline in acoustic energy if the user traveled from 6 to 12 meters away from a sound source, using the inverse square law?

dB = 20 log(6 meters = 12 meters)

dB = 20 log(12 meters/6 meters)

dB = 20 log(6 meters/12 meters)

dB = 20 log(6 meters × 12 meters)

Correct! Wrong!

Which of the following scenarios is most likely to cause excessive high-frequency hiss in an audio system?

Poor gain structure

Noise gate thresholds set too low

Poor compression

Source output gain is set too high

Correct! Wrong!

Once the features of the system breakdown have been recognized, what is the suggested next step to restore normal operation?

Logically divide the system in half, and discover which half has the failure

Request that the user provide a more detailed description of the situation

Replace the component that appears to have failed

Examine the system to see if the problem is straightforward to solve and gather further information

Correct! Wrong!
