The aim is to optimize and simplify the acoustical planning process of wooden multi-storey buildings and thereby to contribute to the increase growth of timber construction industry in Europe. For a prediction of the acoustical performance of solid wood constructions, the vibration reduction index Kij is needed. The vibration reduction index can be determined i.a. of the direction-averaged junction velocity level difference and the structural reverberation time. Both quantities need to be measured according to EN ISO 10848. Alternatively, vibration reduction indices for a T- or cross-junction can be derived following the procedures described in prEN ISO 12354-1:2016. However, further knowledge and data of the sound transmission across junctions of CLT is inevitable for a reliable prediction. In this paper a collection of frequency dependent vibration reduction indices for CLT structures will be presented and compared, involving L-, T- and cross-junctions measured by six international laboratories.}, language = {de} } @inproceedings{RaboldChateauvieuxHellwigMecking2017, author = {Rabold, A. and Ch{\^a}teauvieux-Hellwig, C. and Mecking, S.}, title = {Optimierung von Holzdecken in Bezug auf die DIN 4109}, series = {Forum Holzbau HBS}, booktitle = {Forum Holzbau HBS}, year = {2017}, language = {de} }
