Architectural, Acoustic, and Audio System Design for the Modern Music Production Studio Self-Assessment

Question Title

* 1. The frequency response of a digital audio converter is related to:

Bit depth

The digital transmission format used

Sampling frequency

All of the above

None of the above

Question Title

* 2. In digital audio, bit resolution refers to:

The dynamic range of the digital audio system

The number of 0’s and 1’s used to represent each amplitude measurement

The amplitude resolution of a digital audio system

All of the above

None of the above

Question Title

* 3. In digital audio, each sample captures:

The highest frequency of the audio

The speed of the master clock

The amplitude of the audio

The quantization error

None of the above

Question Title

* 4. A flexural absorber will be most effective:

Near a room boundary, where pressure is greatest

Near a room boundary, where velocity is greatest

Applied directly to a wall, where velocity is greatest

Spaced away from the wall, where velocity is greatest

Whether applied directly to a wall or spaced away from it; only the point of reflection matters

Question Title

* 5. To digitally encode the highest frequency in a signal successfully, it must be sampled at a rate at least ________ that frequency.

Equal to

Twice

Three times

Four times

None of the above

Question Title

* 6. When sending digital audio signals from one device to another:

Both devices must be locked to the same speed reference

Clocking from the same speed reference will give the best quality audio, but it’s not critical

A common speed reference is never required in this situation

It’s best to first convert the digital audio into analog audio, since analog always sounds better than digital

None of the above

Question Title

* 7. A balanced audio connection:

Uses three independent conductors

Uses the shield as both return (-) and ground

Helps to minimize noise and interference

"Uses three independent conductors" and "Helps to minimize noise and interference"

"Uses the shield as both return (-) and ground" and "Helps to minimize noise and interference"

Question Title

* 8. On a digital audio meter, 0 dBFS indicates:

The nominal operating amplitude of a digital audio system

The minimum possible amplitude of a digital audio system

The maximum possible amplitude of a digital audio system

"The nominal operating amplitude of a digital audio system" and "The maximum possible amplitude of a digital audio system"

"The minimum possible amplitude of a digital audio system" and "The maximum possible amplitude of a digital audio system"

Question Title

* 9. A frictional absorber will effectively absorb more frequencies:

Applied directly to a wall, where pressure is greatest

Spaced away from the wall, where pressure is greatest

Applied directly to a wall, where velocity is greatest

Spaced away from the wall, where velocity is greatest

Whether applied directly to a wall or spaced away from it; only the point of reflection matters

Question Title

* 10. For effective transmission isolation, one should take advantage of:

Mass

Decoupling

A combination of mass and decoupling

Low frequency coincidence dip

High frequency coincidence dip
