A solid-borne-sound underlay based on a wood-plastics-composite material. A process for production of the solid-borne-sound underlay is also provided. The process involves the step of applying a mixture of wood particles and plastic particles to at least one first conveyor belt with formation of a preliminary web and introduction of the preliminary web into at least one first continuous-flow oven. The process also involves the step of transfer of precompacted preliminary web into at least one twin belt press. The process also involves the step of cooling compacted solid-borne-sound underlay made of wood-plastics-composite material in at least one cooling press.
