résumé In this paper, Impulse response method IRM and finite difference FD are used to model the acoustic radiation in a viscous fluid where the attenuation is obeying a squared frequency law. Some results are presented to illustrate the attenuation effect on the diffraction. A good agreement between the IRM results and those numericallly predicted by FDM is observed.
