Good sound insulation by walls and floors is easily achieved using the inherent mass and the damping qualities of concrete.
Concrete wall solutions typically perform well in acoustic tests. Concrete’s mass provides good acoustic isolation, can provide high levels of sound insulation across a wide range of sound frequencies and can attenuate many noises within buildings. This level of sound insulation achieved provides a valuable contribution to the health and well-being of occupants and users of buildings.
In concrete construction, acoustic performance is achieved with minimal additional materials, therefore there is less reliance on workmanship and acoustic separation is less likely to be compromised over the lifetime of the building.
The sound insulation properties of concrete block-work encompass three key acoustic parameters: mass, stiffness and damping.
