Sound absorbing system for ceiling i.e. wooden beam ceiling, has damping region including flow layers with flow resistance in direction with directional component that is parallel to screed layer in central part

The system (10) has a damping region (18) for damping impact sound and arranged between a full floating screed layer (14) and a raw ceiling (12). The damping region has flow layers (29, 31) including flow resistance in a direction with a directional component that is parallel to the screed layer in...

More Information
Summary:The system (10) has a damping region (18) for damping impact sound and arranged between a full floating screed layer (14) and a raw ceiling (12). The damping region has flow layers (29, 31) including flow resistance in a direction with a directional component that is parallel to the screed layer in a central part. The flow resistance is less than 5 kilopascal second per square meter. The flow layers have thickness in the range of 5 to 10 mm and material-free regions that are connected with each other. Ein schalldämmendes System zur Schalldämmung einer Gebäudedecke, insbesondere einer Holzbalkendecke, umfasst eine schwimmend gelagerte Estrichschicht (14) und einen Körperschall dämpfenden Dämmbereich (18), welcher zwischen der Estrichschicht (14) und einer Rohdecke (12) anordenbar ist. Der Dämmbereich (18) umfasst wenigstens eine Strömungsschicht (29; 31; 42; 56; 61; 67; 71; 83; 91), deren Strömungswiderstand r wenigstens in einer Richtung mit einer zur Estrichschicht (14) parallelen Richtungskomponente im Mittel gering, insbesondere kleiner als 5 kPa s m, ist.
