Abstract
The sound spectrograph shows variations in signal intensity by varying shades of gray to black which, because of the nature of the recording medium, are not susceptible to quantitative interpretation. Several methods are described in this paper for recording amplitude variations in measurable steps. These methods include contours, dot spacing, distinctive shadings, and variable area patterns.
