Development and Calibration of a Sound Propagation Model for the Oregon Coast

Abstract

In this report we present results of a sound propagation modeling study off the coast of Newport, OR. Preliminary acoustic experimental data was also collected by an underwater glider equipped with a hydrophone to measure sound levels in a short transect perpendicular to the coast and away from a sound source. A propagation model was used to simulate the arrivals recorded by the glider’s hydrophone and results were compared to the experimental data. Optimal experimental setup for future measurements using a glider is suggested.
