3
Absorption occurs when sound waves hit...
a flexible room boundary
a hard surface like wood or glass
another wave
a porous surface like foam
4
The angle of incidence is equal to the angle of reflection. True or false?
True
False
5
The control room contains...
the studio's reverb chamber
the recording & mixing gear
the microphones & acoustic instruments
6
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 density and timing of reflections
the number of different spaces provided in a reverb plug-in
7
The Inverse Square Law addresses...
inconsistent level in square waves
increasing level with greater distance from the source
decreasing level with greater distance from the source
consistent level despite greater distance from the source
8
One effective technique for soundproofing a studio is...
an anechoic chamber
the generous application of egg cartons affixed to the walls
a "room-within-a-room"
using earplugs
9
A reverberant sound field consists of...
dense reverberation, phasing effects, & compressed echoes
an impulse and a response
dense reverberation, flanging effects, & compressed echoes
an initial reflection, early reflections, & later denser reverberation
10
Wavelength is...
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
the length of a song
11
A diffusor panel...
diffuses creative tensions during a session
focuses reflections like a parabolic mic
all answers are correct
scatters reflections for a more even ambience in a room
12
The Haas Effect specifies two "zones":
the Fusion zone & the Echo zone
The Fission zone & the Danger zone
the Fission zone & the Reverb zone
the Echo zone & the Reverb zone
13
An anechoic chamber is...
a Live-End Dead-End™ space for mixing
a very live space, usually for testing applications
a completely dead space, usually for testing applications
an echo chamber
14
Comb filtering is caused by...
an effect that slightly clips the audio wave
the gradually decreasing level as a sound wave dies away
too much processing
reinforcements & cancellations from reflected waves
15
A bass trap is...
a bass boost from wall placement of a speaker
a wall cavity meant to break up standing waves
the bass port in some speaker designs
all answers are correct
16
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
17
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 bad music

personal music studios
all answers are correct
smaller recording studios
home studios
19
Standing Waves (or Room Modes) are...
different room shapes for control room designs
irregularities in high-frequency reponse at different locations in a room
irregularities in low-frequency reponse at different locations in a room
20
Live End Dead End ™ is an approach to...
positioning the musicians for a recording
building a project studio
deciding which way a microphone should be pointing
applying absorption to a control room
21
The "mirror trick" is...
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
a technique to imitate the playing style of another musician
