--- STRUCTURE-BORNE NOISE FROM WATER SUPPLY INSTALLATION

---

Abstract

This study investigates the transmission of structure-borne noise generated by water supply installations, with a particular focus on faucets. Laboratory experiments were conducted to evaluate the effects of various pipe fixing methods, wall elbow supports, and faucet types on noise levels. The measurements revealed that PPR clamps and rubber-lined clamps transmit varying degrees of noise depending on hydraulic shocks and water flow rates. Free-hanging pipes consistently demonstrated a significant noise reduction of up to 11.0 dB. The impact of wall elbow support and its attachment to the partition wall also proved critical, with complete removal reducing noise by up to 15.4 dB. The findings emphasize the role of minor construction details in noise transmission and suggest practical strategies to mitigate noise from plumbing systems, particularly in new residential buildings where irregular layouts exacerbate the issue. These results offer valuable insights for improving acoustic standards and minimizing noise complaints in modern housing developments.
