In naval vessel noise control experiment, in order to guarantee the acoustic similarity between the vessel and its model, increasing the model proportion is the core. Actually, it is difficult to carry on large-scale model acoustic experiment in anechoic tank, thus, testing field in natural limited waters becomes the first choice. When vibration and noise control experiment of large complicated structures is conducted in limited water areas, acoustic signal measurement and data processing is of great significance. In natural limited waters, the boundary conditions of acoustic field are unknown, hydrological environment and characteristics of acoustic propagation are complex, difficulty of numerical simulation is big, which increases the processing difficulty of underwater acoustic signal. Experiment studying on acoustic transmitting characteristics of the testing field in limited waters based on reference sound source, in essence, is to transform the measured underwater acoustic radiation of ship at near-field into sound pressure level in the unit distance far away from reference source. Then, adopt AcTUP to explore acoustic characteristics of sedimentary layers and water level selecting principles of the testing field. Lastly, through incoherent analysis of the deviations between experimental values and theoretical values based on ray acoustic theory, the influence rule by basic acoustic parameters on the field acoustic transmitting characteristics is obtained.
