Technical Booklet G Resistance to the Passage of Sound·Page 26·2.5
Wall type 2: Cavity masonry
Cavity masonry walls achieve sound resistance through the combined effect of the mass of each leaf and the isolation between leaves, which is influenced by connections and cavity width.
The resistance to airborne sound depends on the mass per unit area of the leaves and on the degree of isolation achieved. The isolation is affected by connections (such as wall ties and foundations) between the wall leaves and by the cavity width.
