Analyzing Underwater Acoustics with COMSOL Multiphysics®
Duration: 45:51
Developing technologies for underwater communication and navigation requires an understanding of transducer behavior, sound propagation, and how factors such as depth-dependent material properties influence underwater acoustics.
In this archived webinar, see how engineers and researchers can design devices for the efficient detection of marine life and artificial structures using the COMSOL Multiphysics® software. We discuss the differences between multiphysics and multimethod solutions as well as the functionality for both. The video also highlights a series of example models, each focused on a specific use case for underwater acoustics modeling.
