Can dry lining improve soundproofing?

Dry lining can improve soundproofing when acoustic materials are included in the system. Standard plasterboard provides some reduction in noise, while acoustic plasterboard is denser and designed to reduce sound transmission. Better results can be achieved by building an independent timber or metal frame and placing acoustic mineral wool inside the cavity. Two layers of plasterboard can add mass and further improve performance. Joints, edges, sockets and service openings should be sealed carefully because noise can travel through small gaps. The most suitable system depends on whether the problem involves voices, music, television noise, footsteps or vibration. Dry lining can reduce everyday noise between rooms or neighbouring properties, but complete soundproofing may also require improvements to floors, ceilings, doors and connected walls.
