Summary: | The acoustic performance of a CLT-based building mockup was investigated within the scope of the ADIVBois acoustic technical commission with the objective of defining wood building constructions fulfilling requirements. The CLT-based building is a three-floor construction with four rooms on each level. Measurements from junction characterization to airborne and impact sound insulations were taken. The implemented floor systems were first tested in a laboratory to evaluate their acoustic performance. Predictions based on the EN ISO 12354-1 and -2 standards were compared to building acoustic measurements. The effect of using the tapping machine and the rubber ball as impact sources was investigated both in laboratory and in the CLT-based building mockup. The effect of the apparent post between rooms is also presented with an associated simple approach to take it into account in predictions. This paper summarizes the obtained results. |
