Audio Terms and Definitions
Sound Wave
A vibrational disturbance that involves the mechanical motion of molecules transmitting energy from one place to another.
Compression
Reducing a signal’s output level in relation to its input level to reduce dynamic range.
Frequency
The # of times per second that a sound source vibrates, is expressed in hertz (Hz).
Hertz
Unit of measurement of frequency; numerically equal to cycles per second (cps).
Infrasonic
The range below the frequencies is audible to human hearing.
Ultrasonic
The range above the frequencies of human hearing.
Pitch
The subjective perception of frequency – the highness or lowness of a sound.
Fundamental
The lowest frequency a sound source can produce. In other words, it is also called the first harmonic or primary frequency which is the lowest, or basic, pitch of a musical instrument.
Sound Frequency Spectrum
The range of frequencies audible to human hearing: about 20 to 20,000 Hz.
Octave
The interval between the two frequencies that have a tonal ratio of 2:1.
Bass
The low range of the audible frequency spectrum; is usually from 20 to 320 Hz.
Midrange
The part of the frequency spectrum to which humans are most sensitive; is the frequencies between roughly 320 Hz and 2,560 Hz.
Treble
The frequency range between roughly 5,120 Hz and 20,000 Hz, the highest two octaves audible to human hearing in the sound frequency spectrum.
Equalization
A signal-processing device that can boost, attenuate, or shelve frequencies in a sound source or sound system.
Amplitude
The magnitude of a sound wave or an electric signal is measured in decibels.
Decibel (dB)
A relative and dimensionless unit to measure the ratio of two quantities.
Wavelength
Distance between two peaks of a wave
Velocity
Speed in a given direction
Harmonic
Is a multiple of the fundamental frequency
Phase
Factor in the interaction of one wave with another, either acoustically or electronically
