The recent yoears have whitnessed a rapid developement of new construcion materials, some of these showing anisotropic properties, while the constructions are light and very strong. These new materials appeared in the last few years, hence it is necessary to determine the acoustical parameters of such constructions. This study is concered with calculations of sound reduction index of three-layered systems made from thin, transparent polyurethane foil. Experimental tests were run for created numerical models and experimental results are compared with numerical calculations.
