Which is high accuracy in analysis, easy to operate, and can express the rule that hydrodynamicnoise intensity changed along with the speed. power spectrum and other factors.
该软件分析精度高、易操作，可给出流噪声强度随航速变化的规律和功率谱等指标。

Then the pipe system becomes the main noise resource of quite submarine, when propeller noise, hydrodynamicnoise and machinery noise of facility base are controlled effectively.
For the case of hydrodynamicnoise, in which the range of the frequency-thickness product of interest is relatively low, the symmetric zero-order mode dominates the noise radiation.
