Abstract

A block analytic-numerical multipоles technique is developed for solving of acoustical problems. The technique differs from the finite-element method due to approximation scheme used to describe a solution required. The approach offered is applied to solve some acoustical example problems. Obtained results affirms computational efficiency of the block analytic-numerical technique for solving of boundary value problems.
