Multilayered board with oblique slots in the board core to reduce the structure-borne sound radiation and to increase the sound insulation in the case of maintaining the mechanical stability.

摘要

Multi-layer board having 1 to reduce the structure-borne sound radiation with an increased mechanical stability in the case of application of force, comprisinga first cover layer 2,a second cover layer 3, andat least one core layer 8, whereinthe at least one core layer 8 between the first and the second cover layer 2, 3 is arranged,wherein the at least one core layer 8 at least one first slanted slot 4a, b,wherein the at least one first slanted slot is designed in such a way, upon actuation of an external force f on one of the cover layers 2, 3 the at least one first slanted slot from a certain limit force f_g by means of mechanical deformation of the multilayered board must be closed; andthe closure of the at least one first slanted slot again results in a substantially continuous core layer.
