Prüfverfahren zur Bestimmung der Trittschalldämmung von Balkon‐Anschlusselementen.

Test method to determine the impact sound insulation of thermal insulation elements of balconies The thermal insulation of balconies and access balconies from the façade is usually performed by using reinforced thermal insulation elements. These elements also affect the impact sound transmission and are therefore relevant for the acoustic planning of a building. In a research project at the University of applied sciences Stuttgart a laboratory test procedure to provide acoustic quantities of such elements was developed. The relatively compact test set‐up consists of a balcony that is connected to a ceiling by a thermal insulation element. The impact sound reduction in analogy to floor coverings and the impact sound difference as insertion loss with reference to a rigidly connected balcony can be determined using structure‐borne sound measurements. Both values can be used for product description and to predict the impact sound transmission in a building according to EN ISO 12354‐2. This article describes the test procedure and validates it by means of finite element simulations. [ABSTRACT FROM AUTHOR]
