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