| Abstract: | In order to develop the aeroacoustic generator of the high sound intensity of a kind of low frequency, on the basis of the thing that the theory is analyzed to the course of sounding pneumatically, we utilize hydrokinetics to calculate to analyze with acoustics that the software of combining has carried on the systematic ground emulation and calculation, draw aeroacoustic to sound match influence law of parameter of system, for being aeroacoustic to sound system is it is it offer reference basis to study to design. |
