In situ and laboratory measurement of service equipment decoupling in lightweight constructions

• The latest version of the Swiss standard for building acoustics (SIA181) introduced a new measurement method, based on a balanced- Arm hammer, for evaluating the decoupling performance of service equipment. This method was developed for reproducing in a standard manner the manipulation of service equipment in bathrooms and kitchens. In this study, we are investigating the relevance of such method for timber frame building where decoupling performances are particularly important. This study determines the advantages and the limitations of this methodology, which allows identifying the main propagation paths for equipment noise. A series of in-situ measurements has been performed to identify the best building constructions, service equipment configurations but also some workmanship errors. Laboratories investigations have also been conducted to understand and optimize the decoupling of two type service equipment systems.
