Project description In a pilot study involving laboratory investigations of floor-level shower elements, all key acoustic parameters of relevance in the German-speaking region were determined metrologically on a test-bench simulating a building. The results of the structural investigation revealed non-compliance with nearly all normative and private requirements as per DIN 4109, VDI 4100, Austrian standard B8115-2 and SIA 181. The aim of this project is product optimization through acoustic decoupling of a shower element by means of a suitable impact sound insulation mat, as well as investigation and optimization of the shower element's edge connections. The acoustic influence of edge connections is to be quantified as accurately as possible here. Also examined here is the influence of a screed structure surrounding the shower element as well as tiling of adjacent components (walls and floors). To be conducted for this purpose are experimental (preliminary) investigations on a test bench with receiver-plates or a test bench simulating a building.
