Simulation of acoustic scattering by multiple obstacles in three dimensions

We present an algorithm for simulating acoustic scattering by multiple three dimensional sound-hard, sound-soft, or absorbing impenetrable particles. We demonstrate the high order accuracy of the algorithm by simulating multiple scattering at a range of frequencies. The high order multiple acoustic scattering algorithm in this work facilitates understanding of the interactions of acoustic waves scattered by multiple convex and non-convex bodies.
