Description
Drainpipe noise can be a prominent annoyance and privacy problem in modern housing. Heavy pipe systems with low vibration mobility are standard practice for achieving acoustic comfort in solid construction buildings. However, it is not clear whether the vibro‑acoustic performance of the pipe systems in massive constructions can be transferred to lightweight construction. This study examines the influence of source-receiver mobility interaction on drainpipe noise transmission. Laboratory measurements according to EN 14366-1 were performed for both a heavy, low mobility pipe system and a lighter standard system, each mounted on both heavy and lightweight wall types. The measurements are complemented by prediction calculations based on EN 12354-5, which enable a systematic variation of the building construction. For the investigated configurations, the results indicate that the acoustic performance of the pipe systems is influenced by the source-receiver mobility interaction and the building transfer functions. On the heavy wall, the two pipe systems showed comparable noise levels, and hence, similar single number quantity (SNQ) values. In contrast, on the lightweight constructions, the comparable performance of the two pipes was not preserved: the lower-mobility heavy pipe showed clearly lower SNQ in one lightweight construction, while the lighter standard pipe showed lower SNQ in the other lightweight construction. These results indicate that the acoustic performance of wastewater systems determined in one construction is not directly applicable to other constructions: the performance depends on the combined effect of the source-receiver mobility interaction and the building transfer function.
