Abstract
The usefulness of the Schilling-Whitson sound diffraction apparatus is enhanced by mounting a small lamp on the detecting microphone. This allows the observer to correlate better the position of the microphone with the intensity of the sound. Photographic prints of the sound pattern can be made by focusing light from the lamp on to a sheet of photographic paper. For classroom use, copies of the sound-pattern prints mounted on pieces of cardboard, large enough so that the positions of the radiating apertures can be indicated, have proved useful.
