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
