能够产生辐射噪声谱，而且可以修改船速，螺旋桨速等(Can produce noise, and can modify the speed of the ship, propeller speed etc.)

根据舰船螺旋桨噪声一书给出的计算空泡噪声的公式，简便计算各种条件下的螺旋桨噪声级的程序(According to the formula for calculating the cavitation noise given in the book "Propeller Noise of Ships", the program for calculating the propeller noise level unde
