Abstract
The invention relates to a sound-insulating board, in particular a footfall insulating board for laminate floors or similar applications. The sound-insulating board is distinguished by a continuous transition of its density from the one large-area side to the other large-area side of the board and comprises a mixture of unglued wood fibers, a binder and/or supporting fibers and a mixed plastic, such as arises from the dual system during the recovery of plastic parts.
