Abstract:
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.
