摘要

The method for producing a sound insulating compound element, in particular, for motor vehicles involves joint compression of a heavy plasticized material and an open-pore elastic absorber material. This process takes place in a press whose top tool is provided with cutouts serving for rib formation. An independent claim is also included for a resultant sound insulating compound element.
