Vibrational energy transmission through wall junctions in buildings

摘要

The total loss factors and vibrational power transmission losses were measured in-situ in real buildings having non-right-angled wall junctions. The dependence of the vibration power transmission loss with junction angles was discussed. It was found that the transmission losses increases as the included angle increases beyond 90°. It was shown that findings can provide useful information for the further development of the structure-borne noise prediction scheme for use in real buildings.
