In this paper explorative measurements are discussed to investigate the transmission paths that were responsible for the airborne sound transmission through a partition wall of a specific building. A wide range of measurement tools were used for that purpose: acoustic measurements to determine DnT according to ISO16283-1, followed by structural vibration measurements on parts of the partition wall as well as on the window profile, and sound intensity measurements. All types of measurements point towards a structural vibration transmission path of the window frame. The effect of a rubber dilatation in the window frame profile is discussed as well.
