The hydrodynamic noise of underwater vehicles during high-speed navigation has always been particularly prominent. Hydrodynamic noise is divided into direct radiation noise of fluid pulsating pressure and flow-induced noise. Flow-induced noise is generated by structural vibration caused by turbulent pulsating pressure on the structural surface. Due to the randomness of turbulent disturbances，the surface pulsating pressure is not uniform in time and space，so the statistical analysis method is needed to calculate flow-induced noise. The calculation methods for turbulent boundary layer pulsating pressure mainly include traditional semi-empirical formula calculation and CFD flow field analysis calculation. Flow-induced noise calculation uses method combined with these two，extracting the parameters required for the frequency wavenumber spectrum prediction model in flow field simulation，and respectively using the finite element method and statistical energy method for calculation. The results are compared with those obtained from theoretical empirical formula methods，and the noise results of the two are quite consistent.
