Sound transmission loss is an major content of underwater acoustic survey, also is an important parameter of acoustic field prediction. By using time-frequency analysis and energy calculation, This essay studies the processing method of sound transmission data, analyzes underwater acoustic environmental properties and spatial distribution of sound transmission loss, compares experimental data with Parabolic Equation model (RAM) simulation results. The results show good agreement with experimental data and simulations, validating the suitability of acoustic model as well as the feasibility of acoustic field prediction.
