Terminology Flashcards
Soundscapes
Sounds a certain era produces
Just Noticable Difference (JND)
The smallest amount of change applied to a sound that a listener can perceive
The Golden Rule
“Serve the purpose of the production”
Stereo Field
Two monitors creating an illusion of acoustic space, the space itself is known as the stereo field
Horizontal Space
Determines horizontal position
- associated with size & location
Vertical Space
Associated with frequency or pitch (motion)
Proximity (Presence / Absence)
How near or far an object is in relation to the listener
- relationship between object & space
Time
Sound characteristics changed based on variables (amp, frequency, proximity, etc.)
Sound Merging
Multiple sounds merge when they occupy the same space, creating a new single object or soundscape, surrounding its own space
Sound Definition
Multiple sound objects are clearly defined when occupying their own space
Imaging
Combination of Definition & Merging
Localization
A listeners ability to identify the location or origin of a specific sound in an environment
Frequency Space
Audio frequency space or domain / Audio Spectrum
Frequency below 20Hz is called:
Infrasonic
Frequency above 20kHz is called:
Ultrasonic
Octave
Doubling of frequency
Human Frequency Range
20Hz-20kHz (20,000Hz)
Perceptual Center Frequency
Methods to find the center between 2 frequencies
What 2 frequencies are included with the Perceptual Center Frequency?
Arithmetic (Linear)
Perceptual (non-Linear, how we hear)
LF (Low freqs.)
30Hz-250Hz
- bottom end, dark, thunderous, heavy
Mid (Mid freqs.)
250Hz - 2000Hz
- energy, intensity, speech intelligibility
HF (High freqs.)
2000Hz-16000Hz
- top end, brightness, air, light
A unique combination of Frequencies create:
Timbre
Timbre
The combination of sound characteristics that distinguishes it from other sounds of the same pitch & volume
