The current noise that a generic underwater vehicle spreads is modeled and dissolved in a numerical environment. The Great Burgae Simulation (LES) and the final volume methods in which the hydrodynamic resolution is carried out and the acoustic analogues in which the sound spread is modeled have been combined with the levels of sound pressure, sound direction, noise spectrum and acoustic trace found in the fluid environment. The intensive network structure was used to increase accuracy and second-degree separations were performed. Using the pressure-based commercial code, the flow dynamics equations are filtered and the pressure information obtained from here is defined as an acoustic source. However, a number of fiction has been created to be appropriate by dealing with the audit work available in the literature test data to verify the followed method. Hydrodynamic test data are compared with numerical resolution of the 4382 pervans with different speeds and rotations. Furthermore, the density levels of the noise harmonics formed by the VP1304 pervane were found in the receiver points assigned in the numeric environment as hybrid and compared to the test results. The noise characteristics that the underwater vehicle spread along with the method was identified numerically by the Lighthill-Curle method and the classification of the noise sources hydroacoustically was carried out. Thus, the feasibility and implementation of hydroacoustic work, which is an important criterion in the design and development stages, has been shown.
