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