dB products maximize sound insulation
The influence of sound absorption on room-to-room sound insulation
ROCKFON's dB products have been designed to block sound from travelling from room to room, providing a unique combination of both outstanding sound insulation and sound absorption in one panel.
There is a strong synergy between sound absorption and the room-to-room sound insulation experienced in practice. This is not reflected by the Dn,f,w value measured in laboratories. At equal Dn,f,w value, the use of a highly sound-absorbent ceiling will result in a lower sound pressure level in the receiving room.
The ceiling with the highest αw will do a better job of lowering the sound pressure in both the sending and the receiving room. The impact of sound absorption on the perceived sound pressure level can be calculated and has been verified through in-situ testing.
