Abstract

The article describes the absorption properties of acoustic materials. The emphasis is on rubberlike materials with inclusions of cavities that provide resonance dissipation mechanisms. Testing of the developed methodology and a study of the accuracy of the method by comparison with previously published results are presented. Changes in the acoustic properties of a heterogeneous material under external load conditions in a linear formulation are analyzed.
