2
Absorption occurs when sound waves hit...
a porous surface like foam
another wave

a hard surface like wood or glass
3
A reverberant sound field consists of...
dense reverberation, flanging effects, & compressed echoes
an impulse and a response
an initial reflection, early reflections, & later denser reverberation
dense reverberation, phasing effects, & compressed echoes
4
The "mirror trick" is...
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
a psychological method for getting a good take from an artist
5
The Precedence Effect deals with...
sounds from different directions separted by a very short delay
sounds from different directions separted by a very long delay
the loudest perceived track in a mix
the softest perceived track in a mix
6
A diffusor panel...
diffuses creative tensions during a session
all answers are correct
scatters reflections for a more even ambience in a room
focuses reflections like a parabolic mic
7
An anechoic chamber is...
a Live-End Dead-End™ space for mixing
a completely dead space, usually for testing applications
an echo chamber
a very live space, usually for testing applications
8
In a reverberant sound field, diffusion relates to...
the density and timing of reflections
In a reverberant sound field, diffusion relates to...
the number of different spaces provided in a reverb plug-in
the relative level of the dry signal and the reverb signal
9
"Project Studio" is a catch-all term for...
home studios
personal music studios
all answers are correct
smaller recording studios
10
A bass trap is...
the bass port in some speaker designs
a bass boost from wall placement of a speaker
all answers are correct
a wall cavity meant to break up standing waves
11
Phase is...
a period when novice mixers tend to use too much EQ
an effect generated with a ≥50-mlliisecond delay
a measurment of the period of one cycle of a sound wave
12
Standing Waves (or Room Modes) are...
irregularities in low-frequency reponse at different locations in a room
irregularities in high-frequency reponse at different locations in a room
different room shapes for control room designs
13
One effective technique for soundproofing a studio is...

False
16
Psychoacoustics refers to...

18
Comb filtering is caused by...
the gradually decreasing level as a sound wave dies away

the Fission zone & the Reverb zone
21
Live End Dead End ™ is an approach to...
building a project studio
deciding which way a microphone should be pointing
positioning the musicians for a recording
applying absorption to a control room
