using earplugs
a "room-within-a-room"
an anechoic chamber
3
The angle of incidence is equal to the angle of reflection. True or false?
False
True
4
Psychoacoustics refers to...
how our ears respond to dangerously loud sound waves

5
The control room contains...

the recording & mixing gear
6
Standing Waves (or Room Modes) are...
irregularities in high-frequency reponse at different locations in a room
irregularities in low-frequency reponse at different locations in a room
different room shapes for control room designs
7
The Haas Effect specifies two "zones":
the Fusion zone & the Echo zone
The Fission zone & the Danger zone
the Fission zone & the Reverb zone
the Echo zone & the Reverb zone
8
Golden Mean room dimensions are intended to minimize the incidence and severity of standing waves. True or false?
False
True
9
Comb filtering is caused by...
reinforcements & cancellations from reflected waves
too much processing
the gradually decreasing level as a sound wave dies away
an effect that slightly clips the audio wave
10
Absorption occurs when sound waves hit...
another wave
a porous surface like foam
a hard surface like wood or glass
a flexible room boundary
11
"Project Studio" is a catch-all term for...
all answers are correct
smaller recording studios
home studios
personal music studios
12
A bass trap is...
a wall cavity meant to break up standing waves
all answers are correct

13
The Precedence Effect deals with...
sounds from different directions separted by a very long delay
the loudest perceived track in a mix
the softest perceived track in a mix
sounds from different directions separted by a very short delay
14
Phase is...
a period when novice mixers tend to use too much EQ
a measurment of the period of one cycle of a sound wave
an effect generated with a ≥50-mlliisecond delay
15
The "mirror trick" is...
a psychological method for getting a good take from an artist
a technique to imitate the playing style of another musician
a simple way to locate problematic reflections
a way to create sight lines from control room to live room
16
Wavelength is...
the distance a wave travels in the time it takes to complete one cycle
the length of a sustaining note, like from an organ
the length of a song
the decay time of a note with a gradual falloff in level
17
In a reverberant sound field, diffusion relates to...
the relative level of the dry signal and the reverb signal
the number of different spaces provided in a reverb plug-in
In a reverberant sound field, diffusion relates to...
the density and timing of reflections
18
Live End Dead End ™ is an approach to...
applying absorption to a control room
positioning the musicians for a recording
building a project studio
deciding which way a microphone should be pointing
19
The Inverse Square Law addresses...
inconsistent level in square waves
increasing level with greater distance from the source
decreasing level with greater distance from the source
consistent level despite greater distance from the source
20
A reverberant sound field consists of...
an impulse and a response
an initial reflection, early reflections, & later denser reverberation
dense reverberation, flanging effects, & compressed echoes
dense reverberation, phasing effects, & compressed echoes
21
An anechoic chamber is...
a completely dead space, usually for testing applications
a Live-End Dead-End™ space for mixing
a very live space, usually for testing applications
an echo chamber
