Abstract:

Basic research on nonlinear acoustics in air was performed during calendar years 1971 and 1972. The projects described in this report are as follows Saturation of acoustic waves directional beams of intense sound diffraction of N waves focusing of N waves by a spherical mirror propagation of intense periodic waves in a tube propagation of finite-amplitude noise propagation of intense acoustic signals through the earths atmosphere parametric acoustic array in air and, parametric reception.
