Vertical airborne sound insulation

The airborne sound insulation of a floor structure can be improved by means of a suspended ceiling system. Measured sound insulation is the same independent if you measure from the room below to the room above or the other direction. Improvements are always linked to a specific type of floor structure.

Vertical airborne sound insulation values

Improvement of airborne sound insulation measured in laboratory ΔRw  according to ISO 140-3 and ISO 717-1:

The improvements are linked to a homogenous concrete floor of normal thickness (160-200 mm) and with a plastic carpet.
