Abstract: Cross-Laminated Timber (CLT) is a building technology that is becoming increasingly popular due to its sustainability and availability. Nevertheless, CLT structures present some challenges, especially in terms of both structureborne and airborne insulation. In this paper, a 200-mm CLT floor was characterized in the laboratory, according to ISO standards, by using a standard tapping machine in order to understand its vibro-acoustic behavior in terms of radiation efficiency for structural excitation. In particular, experimental tests were compared to analytical prediction models available in the literature to check the accuracy of simulation methods in the prediction of the radiation capability of CLT structures.
