This paper discusses the results of an experimental campaign that lead to the characterisation of flanking transmission in CLT structures with different connection systems. The vibration reduction indices Ki j were measured in accordance with the ISO 10848-1 standard in order to provide data suitable to calculate the apparent reduction index according to the EN 12354-1 standard. The research explored several vertical and horizontal junctions on which different number and the type of screws and plates, different CLT panels, and resilient materials at the wall-floor junction were tested. The analysis of these data will hopefully provide a significant tool to improve the accuracy of the prediction methods and to help the acoustic designer of timber building.

Abstract
This paper discusses the results of an experimental campaign that lead to the characterisation of flanking transmission in CLT structures with different connection systems. The vibration reduction indices Ki j were measured in accordance with the ISO 10848-1 standard in order to provide data suitable to calculate the apparent reduction index according to the EN 12354-1 standard. The research explored several vertical and horizontal junctions on which different number and the type of screws and plates, different CLT panels, and resilient materials at the wall-floor junction were tested. The analysis of these data will hopefully provide a significant tool to improve the accuracy of the prediction methods and to help the acoustic designer of timber building.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
