Phase Distortions Due to Nonlinear Effects in an Acoustic Field
Conference paper
Abstract
Linear superposition theory is commonly used to obtain acoustical diffraction patterns for weak acoustic signals. As the sound intensity is increased nonlinear effects set in. These can be responsible for amplitude as well as phase distortions of the primary interfering waves. The present chapter discusses quantitatively the magnitude of the phase distortion introduced by the second-order effects of wave-wave interaction for a system of two monochromatic interfering two-dimensional beams.
