1
Psychoacoustics refers to...

how our ears physically respond to sound waves
2
The angle of incidence is equal to the angle of reflection. True or false?
False
True
3
Wavelength is...
the decay time of a note with a gradual falloff in level
the length of a song
the length of a sustaining note, like from an organ
the distance a wave travels in the time it takes to complete one cycle
4
"Project Studio" is a catch-all term for...
all answers are correct
personal music studios
smaller recording studios
home studios
5
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
6
The "mirror trick" is...
a simple way to locate problematic reflections
a psychological method for getting a good take from an artist
a technique to imitate the playing style of another musician
a way to create sight lines from control room to live room
7
A diffusor panel...
scatters reflections for a more even ambience in a room
diffuses creative tensions during a session
focuses reflections like a parabolic mic
all answers are correct
8
The Precedence Effect deals with...
sounds from different directions separted by a very short delay
the loudest perceived track in a mix
sounds from different directions separted by a very long delay
the softest perceived track in a mix
9
A bass trap is...
the bass port in some speaker designs
all answers are correct
a wall cavity meant to break up standing waves
a bass boost from wall placement of a speaker
10
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
11
Comb filtering is caused by...
reinforcements & cancellations from reflected waves
too much processing
an effect that slightly clips the audio wave
the gradually decreasing level as a sound wave dies away
12
In a reverberant sound field, diffusion relates to...
the relative level of the dry signal and the reverb signal
In a reverberant sound field, diffusion relates to...
the number of different spaces provided in a reverb plug-in
the density and timing of reflections
13
The Inverse Square Law addresses...
inconsistent level in square waves
decreasing level with greater distance from the source
increasing level with greater distance from the source
consistent level despite greater distance from the source
14
Golden Mean room dimensions are intended to minimize the incidence and severity of standing waves. True or false?
True
False
15
Absorption occurs when sound waves hit...
another wave
a hard surface like wood or glass
a flexible room boundary
a porous surface like foam
16
The control room contains...

17
The Haas Effect specifies two "zones":
the Echo zone & the Reverb zone

The Fission zone & the Danger zone
the Fission zone & the Reverb zone
18
Live End Dead End ™ is an approach to...
applying absorption to a control room
positioning the musicians for a recording
deciding which way a microphone should be pointing
building a project studio
19
One effective technique for soundproofing a studio is...
a "room-within-a-room"
the generous application of egg cartons affixed to the walls
using earplugs
an anechoic chamber
20
A reverberant sound field consists of...
dense reverberation, phasing effects, & compressed echoes
dense reverberation, flanging effects, & compressed echoes
an initial reflection, early reflections, & later denser reverberation
an impulse and a response
21
An anechoic chamber is...
a completely dead space, usually for testing applications
a very live space, usually for testing applications
a Live-End Dead-End™ space for mixing
an echo chamber
