Underwater edge tones
For a test of alternative theories of the mechanism of edge tone production, data are obtained on a slit-jet-edge system set up under water. Photographs of the form of the jet are taken in a schlieren system and the frequencies of the tones measured by a hot-wire anemometer and oscillograph.
Comparison is made with earlier results obtained in air and all are discussed from the point of view of a feedback theory.
