Acoustics Toolbox

The Acoustics ToolBox includes four acoustic models:

1. BELLHOP: A beam/ray trace code (Bellhop users guide)
2. KRAKEN: A normal mode code (Kraken users guide)
3. SCOOTER: A finite element FFP code
4. SPARC: A time domain FFP code

In addition, AT contains BOUNCE, which computes the reflection coefficient for a layered medium and may be used to provide input to BELLHOP. A common input structure has been used throughout so that only minor modifications are needed to switch from one program to another. All the models produce `shade' files that can be processed using a common set of plotting routines to plot transmission loss vs. range or vs. range and depth.
