In residential and other buildings many people are annoyed by noise caused by sanitary installations, including the sound transmission via wastewater pipe systems. To avoid annoyance limits to the maximum allowable sound level in rooms are set in several building regulations. In order to come to decisions on measures during the design stage of a building, it is necessary to predict the sound level based on the design of both building and installation. In this research a model based on Statistical Energy Analysis (SEA) is being developed to describe the sound transmission from pipe systems to building structures and rooms. The mode number of the excited wave types in these elements is relatively high in the I13-octave bands, at least in the mid and high frequency range. Therefore the SEA-approach is useful to describe the sound transmission in this frequency range. To collect loss factor data for the model a measurement method based on the Power Injection Method (PIM) has been developed. This method has been evaluated for a system consisting of a wastewater pipe and a building structure, connected with each other by a clamp. The measurements show good repeatability and reproducibility results. To improve the reciprocity more research has to be done.
