Basic Audio Engineering Test questions
with answers
A sound wave is a vibrational disturbance of ANS - molecules
Sound propagates through the air because ANS - of the elasticity of air
The point in a sound wave at which a partial vacuum occurs is the point of ANS - rarefaction
The number of times in a second a vibration completes one cycle is known as its ANS - Frequency
Direct sound reaches the listener ANS - First, before interacting with any other surface
Hertz is the term used to designate ANS - Cycles per second (cps)
Pitch ANS - is the psychological perception of frequency
The range of the difference in decibels between the quietest and loudest sound is called ANS - Dynamic
Range
The brain can isolate and recognize from what direction a sound is coming from using ANS - ITD, IID,
and HRTF
The time relationship between two or more sound waves at a given point in their cycles is called ANS -
acoustical phase
The elements of a sound envelope are ANS - attack, initial decay, sustain, release
,Prolonged exposure to loud sound can bring on ANS - tinnitus
Indirect sound reaches the listener before it interacts with any other surface ANS - False
When early reflections become smaller and smaller and the time between them decreases until they are
indistinguishable describes ANS - reverberation
reverberation (is): ANS - creates acoustical spaciousness and fills out the loudness and body of a sound
The time it takes a sound to decrease 60 dB-SPL after its steady-state sound level has stopped is known
as ANS - reverberation time
When the direct sound is delayed by 35 milliseconds or more, the listener perceives ANS - echo
Flutter echoes are ANS - short single echoes that come in rapid succession in a small room
Amplitude ANS - is the size of a sound wave AND is determined by the number of molecules (A and B)
The difference between sounds - their tonal quality, or tonal color describes ANS - Timbre
Acoustics is used to describe both the physical behavior of sound in a room and the human perception
of sound. ANS - False
Which one of the following statements applies to psychoacoustics? ANS - the study of human
perception of sound
Noise ANS - is unwanted sound
Resonance results when a vibrating body: ANS - with the same natural frequencies as another body
forces the second to vibrate
, Except for bass frequencies, sound behaves like light in that: ANS - its angle of incidence equals its
angle of reflectance
Sound absorption is ANS - when sound is soaked up by the surface
Sound reflection is ANS - when sound bounces off the surface
Sound diffraction is ANS - when sound spreads around the surface
Sound diffusion is ANS - the even distribution of sound energy in a room
Loudness Distortion occurs when the loudness of a signal _______ ANS - Is greater than the system can
handle
Frequency response of a loud speaker should be ANS - Wide and linear
Appearance of a signal in the reproduced sound that was not in the original sound is ANS - Distortion
When two or more frequencies occur at the same time and interact to create combination tones and
dissonances unrelated to the original sounds is called ANS - Intermodulation distortion
____ occurs when the audio system introduces harmonics into a recording that were not present
originally ANS - Harmonic distortion
____ relates to the inability of an audio component to respond quickly to a rapidly changing signal ANS -
Transient distortion
Polar response of a loudspeaker ANS - Indicates how a loudspeaker focuses sound at the monitoring
position
