Harmonic Radiations in the Field of a Baffled Piston.

Abstract

When the radiation from a baffled piston is sufficiently intense, a number of novel and perhaps useful phenomena related to harmonic generation appear, as a result of nonlinear interactions in the sound field. This paper reports some recent studies of several of the more prominent and interesting of these phenomena; in particular, shock formation, finite amplitude attenuation, and the propagation and directivity of harmonic radiations. Theory pertinent to the delineation of acoustic fields is given, along with the results of several experiments done in a fresh water lake.
