Abstract:

An image model was used to predict the sound pressure field everywhere within isospeed water overlying a sloping absorbing bottom. All lengths scale with the dump distance, which is the distance from the apex of the wedge to the point where the depth is equal to the minimum uniform depth that can support propagation of the lowest normal mode. Measurements made in a laboratory tank with a 9.5 deg. sand bottom with density and speed of sound 2.0 and 1.1 times those of water showed qualitative agreement with the predictions of the model for receiver distances up to 10 dump distances from the apex and 50 dump distances along the shore. Keywords Sound Pressure Field Wedge shaped fluid Substrate of Greater Sound Speed Theses.
