This report describes the structure and operation of a device which provides reliable measurement of changes in the apparent size and brightness of achromatic negative afterimages. Utilizing this device two experiments were conducted to assess the effects of pure tone intensity and frequency on reported size and brightness of afterimages. Intense sound stimulation produced very pronounced increases in afterimage size and brightness. These results were discussed in light of previous Soviet findings.

A transformer mixing network is described which allows the calibration of broad-band masking for portable audiometers that lack a built-in mixing network. For many instruments the transformer network is preferable to the resistive network previously published.
