Patent Images
1. A method for categorizing the nature of a source of sound, comprising:
- (a) detecting a first sound from the source;
(b) detecting a second sound from the source;
(c) converting the first sound to a first image;
(d) converting the second sound to a second image;
(e) displaying the first image to a first eye of a sonar operator; and
(f) displaying the second image to a second eye of the sonar operator.

Abstract
A 3-D sonar image display takes two sonar signals from the same event, slightly displaced from one another in time, space, or both. Each signal is converted from audio to video, and is presented to a separate eye of the sonar operator. The coherent parts of the signal--those actually produced by the event--will be fused by the optical portions of the brain into a three-dimensional image. The noise portions of the signal will not be coherent, and will not produce a three-dimensional image.
