Using different waste as resilient layers for impact sound insulation improvement: New alternative to commercial layers? FJ Garcı́a-Cobos and R Maderuelo-Sanz Nowadays impact noise is increasingly becoming an important issue. A high level of noise clearly affects indoor comfort and livability of dwellings. In order to reduce this effect, one widely used solution are floating floors in which the performance of resilient layers, in terms of impact sound pressure level reduction is a relevant issue. This article analyzed the potential use of different waste as resilient layers to be used in floating floors. These layers can adequately compete with commercially available acoustical products replacing them and showing, in some cases, better impact sound insulation performance with lower thickness.
