Killer Whale

Researchers from San Diego State University and the University of California have been using computer models to mimic the effects of underwater noise on an unusual whale species and have discovered a new pathway for sound entering the head and ears.

Advances in Finite Element Modeling (FEM), Computed tomography (CT) scanning, and computer processing have made it possible to simulate the environment and anatomy of a Cuvier’s beaked whale when a sonar signal is sent out or received by the whale. 

The research paper, published today, Monday, February 4, 2008, in the Institute of Physics’ Journal, Bioinspiration & Biomimetics, is a catalyst for future research that could end years of speculation about the effects of underwater sound on marine mammals.
