Abstract | Fire stops can introduce a physical connection between the two sides of a double-stud wall, hence providing structural flanking paths for transmission of vibration which worsens the sound insulation. This study primarily addressed the specific case of a load-bearing party wall with double wood studs, supporting a floor with wood joists perpendicular to the party wall and a floor deck or sub-floor of 15.9 mm OSB.Even without structural transmission of vibration through a fire stop, the sound insulation in a real building is normally affected by flanking transmission. Addition of a fire stop provides yet another path for vibration transmission between the rooms, and hence tends to worsen the sound insulation further. This study examines how a fire stop at the floor/wall junction can degrade the apparent sound insulation of the partywall (the nominal separation) by increasing structural transmission of vibration around that wall via the connected floor system (the flanking path). |
