Materials for impact noise insulation are tested according to the standards ISO 140-8 and ISO 717-2 with laboratory measurements of impact noise level attenuation on a concrete slab. However, the behavior of such materials can be different when applied on non-homogeneous floors. In this work have been reported some data of impact noise level attenuation measured in laboratory on a concrete slab and on a hollow brick and concrete bare floor, built with the same junction typology and with no flanking transmission, to evaluate the difference of the same materials applied to different structures.

Abstract
Materials for impact noise insulation are tested according to the standards ISO 140-8 and ISO 717-2 with laboratory measurements of impact noise level attenuation on a concrete slab. However, the behavior of such materials can be different when applied on non-homogeneous floors. In this work have been reported some data of impact noise level attenuation measured in laboratory on a concrete slab and on a hollow brick and concrete bare floor, built with the same junction typology and with no flanking transmission, to evaluate the difference of the same materials applied to different structures.
