Properties of SOUND
This is a vibration that propagates an acoustic wave through a medium.
What is "sound"?
This is the range of human hearing, in Hz
What is "20-20k"?
Acoustic treatments designed to take in sound's vibrational energy, where different materials have different effectiveness, or coefficient.
What is an "absorber"?
This type of microphone is rugged and durable and can handle a wide dynamic range
What is a "dynamic" microphone?
This is the type of balanced cable that a microphone uses
What is "XLR"?
Found on the Y-axis of a waveform, this is the technical name for what we call "volume" or "loudness"
What is "amplitude"?
This occurs when two or more waves combine in a way that involves cancellation and a decrease in amplitude
What is "destructive interference"?
There are acoustic treatment panels designed to scatter sound waves in multiple directions
What are "diffusers"?
This type of microphone has a wide frequency response and requires phantom power.
What is a "condenser" microphone?
This is a centralized unit used to route audio signal around a studio
What is a "patch bay"?
This is the distance between two corresponding parts of a sound wave
What is "wavelength"?
This occurs when two or more sound waves combine to produce a wave with a larger amplitude
What is "constructive interference"?
Acoustic treatments are often put in corners to avoid the buildup of this type of frequency
What is "bass"? "low frequencies" also accepted
This is the number of volts typically required to power a condenser microphone
What is "48"?
The practice of setting each amplification stage in a signal chain to get the best signal to noise ratio
What is "gain staging"?
This is the number of wave cycles per second of a sound wave, as measured in Hertz
What is "frequency"?
This is the term for the bending and reforming of waves around obstacles or through openings
What is "diffraction"?
This is a studio construction technique to avoid rumble coming in through the building's foundation
What is a "floating floor"? "Riser" is also accepted
Name three types of polar patterns
Cardioid, Omni, Figure of 8
A device meant to increase the overall gain of a microphone (or other) signal
What is a "preamp"?
This is the unique quality of a sound that differentiates it from others, even if they have the same pitch and loudness.
What is "timbre"?
Occurs when a signal adds a delayed version to itself, causing constructive and destructive interference. Commonly caused by a sound source being too close to a boundary
What is "comb filtering"?
This is a studio construction technique used to prevent standing waves in a room.
What are "non-parallel walls"?
This is a chart that shows how well a microphone will pick up certain frequencies
What is a "frequency response chart"?
This is the fundamental unit of a mixing console or digital audio workstation (DAW) that is responsible for processing individual audio signals and typically has controlls for gain, EQ panning and volume.
What is a "channel strip"?
