1
A diffusor panel...
scatters reflections for a more even ambience in a room
all answers are correct
focuses reflections like a parabolic mic
diffuses creative tensions during a session
2
The control room contains...
the microphones & acoustic instruments
the studio's reverb chamber
the recording & mixing gear
3
Psychoacoustics refers to...
how our ears respond to dangerously loud sound waves
how our ears physically respond to sound waves
how our brains interperet audio signals from our ears
how our ears respond to bad music
4
Comb filtering is caused by...
the gradually decreasing level as a sound wave dies away
reinforcements & cancellations from reflected waves
an effect that slightly clips the audio wave
too much processing
5
Standing Waves (or Room Modes) are...
irregularities in high-frequency reponse at different locations in a room
different room shapes for control room designs
irregularities in low-frequency reponse at different locations in a room
6
A bass trap is...
all answers are correct
a bass boost from wall placement of a speaker
the bass port in some speaker designs
a wall cavity meant to break up standing waves
7
The Haas Effect specifies two "zones":
the Echo zone & the Reverb zone
The Fission zone & the Danger zone
the Fission zone & the Reverb zone
the Fusion zone & the Echo zone
8
The angle of incidence is equal to the angle of reflection. True or false?
True
False
9
Live End Dead End ™ is an approach to...
applying absorption to a control room
deciding which way a microphone should be pointing
positioning the musicians for a recording
building a project studio
10
Golden Mean room dimensions are intended to minimize the incidence and severity of standing waves. True or false?
False
True
11
One effective technique for soundproofing a studio is...
an anechoic chamber
a "room-within-a-room"
using earplugs
the generous application of egg cartons affixed to the walls
12
The Inverse Square Law addresses...
inconsistent level in square waves
consistent level despite greater distance from the source
decreasing level with greater distance from the source
increasing level with greater distance from the source
13
Phase is...
a measurment of the period of one cycle of a sound wave
a period when novice mixers tend to use too much EQ
an effect generated with a ≥50-mlliisecond delay
14
A reverberant sound field consists of...
an initial reflection, early reflections, & later denser reverberation
dense reverberation, flanging effects, & compressed echoes
dense reverberation, phasing effects, & compressed echoes
an impulse and a response
15
The "mirror trick" is...
a way to create sight lines from control room to live room
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
16
Absorption occurs when sound waves hit...
a porous surface like foam
a hard surface like wood or glass
another wave
a flexible room boundary
17
An anechoic chamber is...
a very live space, usually for testing applications
a Live-End Dead-End™ space for mixing
an echo chamber
a completely dead space, usually for testing applications
18
Wavelength is...
the length of a song
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 decay time of a note with a gradual falloff in level
19
"Project Studio" is a catch-all term for...
personal music studios
all answers are correct
home studios
smaller recording studios
20
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
the density and timing of reflections
In a reverberant sound field, diffusion relates to...
21
The Precedence Effect deals with...
sounds from different directions separted by a very short delay
the softest perceived track in a mix
sounds from different directions separted by a very long delay
the loudest perceived track in a mix
