Acoustic Intensity in the Interaction Region of a Parametric Sonar

Abstract

The fundamental goal of this project was to measure acoustic intensity in the strong interaction region of a parametric source. The expected benefits of such a measurement are (1) a clear definition of the source-generation region, and (2) an ability to separate local generation (the reactive field) from propagation (the real or active field).
