SOLVING AN ACOUSTIC WAVE SCATTERING PROBLEM ON A SET OF IRREGULAR DISTRIBUTED PARTICLES

An analytical-numerical approach to solving the problem of scattering of acoustic waves by many small particles is investigated, based on the assumption that the distance between them is greater than their radius. It is assumed that the distances between the particles can change, and this change can be specified in different ways. Impedance boundary conditions are specified at the particle boundaries.
