This issue shows the close correlation between thermophysical and acoustic properties of roll flooring materials, such as linoleum, rubber linoleum and carpet covering. The thermophysical properties are characterized by the heat absorption index, S, and the main acoustic feature is the index of impact noise insulation improvement, ΔLnw. The analyses of equations for boundary conditions, as the smooth transition of temperature and heat flow through the interface of two media, allowed revealing the mathematical similarity between acoustic and thermal wave transmission processes, in particular, between the thermal and acoustic impedances. This similarity provided the basis for correlation research between the heat absorption specific coefficient and the index of impact noise insulation improvement values. Therefore, the correlation formula for different types of roll flooring materials was obtained.
