Review To 3D Mapping Of Low Frequency Ambient Shipping Noise.
The history of underwater sound modeling began in the 19th century with early sound speed experiments and evolved rapidly after World War I through sonar development. Over time, modeling advanced from simple 2D ray theories to complex 3D simulations integrating bathymetry, temperature, and ship noise data. Modern approaches now use tools like CFD, AI, and 3D acoustic models to achieve precise predictions of underwater noise propagation, aiding naval, environmental, and research application.
