Die Bedeutung des Verlustfaktors bei der Bestimmung der Schalldämmung im Prüfstand

The sound insulation of buildings should be able to be forecasted by calculation early in the project stage. Therefore building elements are tested in acoustical transmission suites to determine their individual sound transmission. The manufactures are required to label the sound insulation values of their building products. Currently these values are recorded in a number of test institutes with different transmission suite design. As a basic requirement, the results of these measurements should be comparable. It is known, that the loss factor as a measure of vibrational damping has a significant influence on the sound insulation. This aspect has been often neglected in the past due to the problems when measuring the loss factor of building elements. An improved measuring method, developed within this thesis, now leads to more precise values. Furthermore the thesis reports on the results of an inter-comparison laboratory test, and the large differences between results of sound insulation measurements in different transmission suites. These differences can be explained and reduced by taking the loss factor into account, which has been measured by the improved measuring method.
