Abstract : In this project studied the diffraction of acoustic sound wave spherical (issued by a point source) resulting from the coupling half level, one is not resistant to the waves of sound and the other semi-resistant condition to achieve Myers of resistance in the fluid animation. Significance of the project lies in the fact that the source audio bullet can be considered a good approximation of the true source of the voice. The cylindrical source we ended it by using the results obtained from the source bitmap. The sub-resistor represents a situation more realistic levels compared with the solid. As the fluid levels in a mobile that it can expect to benefit from this study in Aerospace Engineering. We have expressed in the form of acoustic diffraction integration using the Fourier transform method and illuminating - Hopf. We have also analyzed the function of the nucleus in the equation and illuminating - Hopf. And we calculated the value of integration using the method of approach. Effect of Mach number and a median absorption band appeared clearly in the audio field diffraction.
