Abstract
The field created by a sawtooth sound wave radiated by a plane with finite aperture is investigated. The solution is based on the separability of the stages of linear diffraction and subsequent nonlinear evolution of the wave along the ray tubes. In the first stage the wave is transformed into a train of pulses whose shape and width depend both on the direction and on the distance from the source. In the second stage the pulses acquire a triangular shape, and the angular distribution of the intensity is smoothed out (isotropization). Estimates are given. The radiation of smooth but distorted field (simple wave) is also discussed.
