Describes a set of programs for computer simulation of sound fields in the ocean. Also features computer-generated images of simulated seascapes and links to other ocean acoustics websites.

Information from Wikipedia on this means of estimating the sound field near a source by measuring acoustic parameters away from the source via an array of pressure or particle velocity transducers.

The principle of operation of these filters is based on the dependence of the diffracted light wavelength on the acoustic frequency. This article considers non-collinear filters based on a single TeO2 crystal.
