CMP Acoustics and Recording Techniques 2

Question 1

What is the primary purpose of a diffuser panel in a recording studio?

Accepted Answer

Scatter sound waves to reduce flutter echo

Answer

Absorb low-frequency energy

Answer

Block outside noise from entering

Answer

Increase reverberation time

Question 2

Which microphone pattern is best for isolating a single instrument on a loud stage while rejecting side bleed?

Accepted Answer

Hypercardioid

Answer

Omnidirectional

Answer

Figure-8

Answer

Subcardioid

Question 3

What does 'critical distance' refer to in room acoustics?

Accepted Answer

The point where direct and reverberant sound levels are equal

Answer

The maximum distance between two parallel walls before flutter echo occurs

Answer

The minimum distance a microphone must be from a source

Answer

The distance at which bass buildup becomes problematic

Question 4

A recording engineer notices a 'comb filtering' artifact in a guitar track. What most likely caused it?

Accepted Answer

Two slightly delayed versions of the same signal being combined

Answer

Too much compression on the signal

Answer

A ground loop in the signal chain

Answer

Excessive high-frequency EQ boost

Question 6

When using a large-diaphragm condenser microphone on a vocalist, where should the engineer place it to minimize plosives?

Accepted Answer

Answer

Directly in front of the lips at 0°

Answer

Below the chin angled upward

Answer

At 90° off-axis to the right

Question 7

What does 'proximity effect' do to a directional microphone's frequency response as it moves closer to a sound source?

Accepted Answer

Boosts low-frequency output

Answer

Attenuates high frequencies

Answer

Increases mid-range sensitivity

Answer

Creates a null at the rear
