Multilayer panel for reduction of sound emissions

The panel (1) has a layer structure provided by a core layer (2) between at least 2 cover layers 3,4), the core layer having a number of slits (5,6) extending in both vertical and horizontal directions in a defined slit architecture across one of its surfaces. The intersecting horizontal and vertical slits are curved and spaced apart by a defined curve distance (k), with a variable curve depth (t) in the thickness (c) of the core layer.
