Abstract
In this work, the far field condition of acoustic multiple scattering by two spheres is studied. The numerical results show that the far fie ld condition depends not only on the precision desired for the far fie ld solutions of the problem, but also on the size of spheres, their di stance, their bearings with respect to acoustic transmitting and recei ving positions, and the signal frequency.
