Impact Sound Insulation Concept for Lightweight Timber Floor

This paper is the second continuation of lightweight timber frame floor construction investigation with a respect to impact noise isolation. We will log on to previous article which dealt with mockup investigation of new LWTF floor conception. The main objectives of research is to design lightweight floor with good impact sound insulation performance to achieve low cost and reduce thickness of construction. In the following chapters well outline results of new floor model on lightweight timber frame construction implemented in laboratory conditions in Belgian Building Research Institute in Limelette, Belgium.
