Nonlinear Air Acoustics.

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 earth's atmosphere; parametric acoustic array in air; and, parametric reception.
