Abstract

This research concerns a 200 mm thick panel filled with water. The airborne sound insulation of this panel was measured in accordance with standard ISO 140-3 [2]. Results show that the single number rating for the airborne sound insulation Rw [3] for an average water layer thickness of 200 mm is 48 dB. This value is comparable to the one of a 150 mm brick wall or 100 mm concrete panel. Predictions about sound insulation of the same system at different thickness and possible applications such as highway sound barrier or construction site sound barrier are presented in the following page
