Virtual Experiments in Marine Bioacoustics: Whales, Fish, and Anthropogenic Sound
Abstract
This programmatic effort has three long-term goals. The first is to simulate bioacoustic interactions within and near individual fish. We developed a methodology that combines x-ray CT scans with tissue elasticity measurements and finite-element modeling software, the vibroacoustic toolkit (VATk). This technique has provided significant insights and discoveries regarding toothed whale bioacoustics (Cranford et al., 2008b; Cranford et al., 2008c), and now, within a fish's head. The second long-term goal is to improve and refine our ability to measure tissue elasticity in samples by building a portable device to measure physical properties from tissue samples so that these quantities can be incorporated into our models. The third and final goal is to validate the finite element models by comparing them to dolphin hearing results from psychoacoustic experiments. Accomplishing these goals has caused us to develop additional functionality to the VATk software.
