Abstract

This paper considers experimental studies of the sound insulation structure of the floor to determine the effect of material thickness, polystyrene concrete and cement-sand screed, as well as the size of the aggregate (polystyrene granules) in polystyrene concrete on the sound insulation properties of floor construction, namely impact protection.

It was determined that the thickness of the cement-sand screed in no way affects the improvement of impact noise. Due to the reduction of the size of the aggregate (expanded polystyrene granule) in polystyrene concrete, it was possible to reduce the thickness of the structure, which did not affect the insulation performance of impact noise.
