Work is underway at CEN/TC126/WG7 to propose a simplified method to characterize building service equipment mounted on lightweight receivers (such as timber based lightweight building elements) as structure borne sound source. In this paper, the draft method is presented and applied to a waste water pipe system rigidly fixed to a lightweight building element. The result (the installed power) is then used as input data to estimate the structure borne noise radiated, which is compared to values directly measured. Moreover, elastic fixations of known performance on heavy building receivers are then inserted between equipment and lightweight building element and their efficiency measured, compared to the original performance and the results analyzed.
