terms:variable_density
Variable intensity. Intensity modulated-time presentation of the acoustic wave train in which the amplitude of the wave form produces a variable photographic density which is displayed versus time. The variations in darkness or density represent relative amplitude. See intensity modulated-time and acoustic log. Compare amplitude-time. See illustration at wave train display.
