摘要

The article presents the acoustic properties of selected polyurethane materials. The study involved a porous polyurethane foam primary and secondary, for whom assigned the value of sound absorption coefficients in the frequency range of 100-1250 Hz. The study was conducted in impedance tube Kundt.
