Development of a measurement method for loss factors in a wastewater pipe - fixation - building structure system based on statistical energy analysis
conference paper
Many people in residential and other buildings are annoyed by noise caused by sanitary installations, including the structure-borne sound transmission via wastewater pipe systems. Due to the turbulent water flow, discontinuities and the relatively large pipe dimensions in especially toilet wastewater systems several wave types are excited in the pipe system. In order to describe the structure-borne sound transmission from a wastewater pipe system via fixations to the building structure in an accurate, but not too complicated way it is good to know which transmission paths play an important role and which paths can be neglected.
The mode number in a 1/3-octave band of some of the excited wave types is relatively high in the mid and high frequency range. Therefore the Statistical Energy Analysis approach is useful to describe the sound transmission in this frequency range. A method for measuring loss factors based on SEA has been developed for a wastewater pipe — fixation — building structure system
