Schallschutz von entkoppelten Massivtreppen - Teil 1: Prüfverfahren im Labor

Impact sound insulation of decoupled heavy stairs - Part 1: Test procedures and prediction.

To improve the impact sound insulation heavy stairs are decoupled from the building using resilient supports. In many countries in Europe (e.g. in Germany) this is actually required to meet legal requirements. However, at present there are no standard procedures available neither for measurement in the laboratory nor for the prediction of the impact sound transmission in buildings. Investigations on representative constructions were carried out in a staircase test facility in order to identify and quantify the parameters that are relevant for the sound transmission of decoupled heavyweight stairs. Based on the results a standard test method is proposed that gives data that can be used to rate and compare the acoustic quality of products and to predict the sound transmission in buildings using EN 12354-2. In this article investigations in the laboratory are presented. A second article addresses the transferability of laboratory results to building situations, in particular the prediction.
