Influences of Ocean Environment on Sound Propagation Based on Bellhop Model

Abstract

The actual marine environment is complex and changeable, and different marine environmental factors have an important impact on sound propagation. Based on the Bellhop model, this paper studies the sound propagation characteristics under different marine environmental factors, quantitatively analyzes the differences in the sound propagation characteristics when the seabed topography, sound velocity profile, and sound source emission angle change, and summarizes the impact on underwater sound propagation under different conditions, so as to provide a theoretical numerical basis for the ocean sound field in the actual complex environment, and further serve the research of the ocean sound field.
