In recent years, the use of sustainable construction materials has increased significantly. It is of paramount importance to increase the general knowledge of acoustic behaviour of these materials. This research presents the results of a comprehensive acoustic investigation of a 200 mm timber slab. Excitations using different acoustic sources are performed. The results to this investigation are reported in this paper, focusing on the sound reduction index, impact noise reduction, static and frequency-dependant Young’s modulus, vibration and modal mapping and radiation efficiency. Finally, a correlation between impact noise levels caused by the tapping machine and the rubber ball is provided.
