Fixing mechanisms

The sound insulation performance of a party element is improved when the fixing mechanism of any additional layer is either resilient or has low stiffness. The general principle is that the less contact area there is between components (i.e. less bridging), the better the acoustic insulation.

For wall or ceiling treatments, metal straps or ties are ideal. Mechanisms that provide a certain degree of resilience, such as spring hangers or resilient bars also improve the insulation and have a reduced impact on the general design features of a space.
