Abstrakt EN: Numerical solution of acoustic wave equation in the time domain is performed. The mathematical model is described by the partial differential wave equation supplemented with appropriate boundary conditions. The goal is to obtain the time evolution of the distribution of acoustic pressure, which can serve as the basis for the solution of various subsequent problems. The paper discusses the results of the numerical analysis of the Gauss monocycle pulse that proceeds from the signal source and incident on the semi-circular acoustic diffuser in a free field, realized by a fully adaptive higher-order finite element method implemented in codes Agros2D and Hermes developed by the hp-FEM group. Selected results of the computations are compared with the data obtained by the commercial code COMSOL Multiphysics.
