Parametric Difference-Frequency Generation of Sound in Air.

Abstract

The study explores the feasibility of parametric difference-frequency generation in air through the interaction of two intense high-frequency sound waves. The sound pressure levels at various distances from the source are shown and the directivity of the difference-frequency is described. An experimental apparatus to generate the high-intensity primary signals is explained and some characteristics of the resonator are described. (Author Modified Abstract)
