Download or read book Ocean Acoustic Propagation Predictions from Averaged Sound Speeds Compared to Individual Sound Speeds written by and published by . This book was released on 1993 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wave propagation through randomness models much ocean acoustic behavior. Random sound speed introduces non-linearity in the differential equations for the ensemble averages. This leads to results which can be significantly different than if an averaged volume parameters, such as sound speed, are used in a deterministic equation. We examine some theoretical aspects of randomness in the normal mode and parabolic equations. As an example, transmission losses in several specific examples are computed where differences result.
