Wall Type 3 – Masonry Between Independent Panels: Sound Resistance Factors
The sound insulation performance of Wall Type 3 depends on the mass per unit area of the masonry core and the isolation and mass of independent panels on both sides.
The resistance to airborne sound depends partly on the type and mass per unit area of the core, and partly on the isolation and mass per unit area of the independent panels.
Note – Wall type 3 can give high resistance to the transmission of both airborne sound and impact sound on the wall.
