ABSTRACT:
A multi-layered sound-insulating panel for motor vehicles, or similar, consisting of at least one dense layer and one resilient layer between the dense layer and the part of the motor vehicle, or similar, to which the panel is attached, makes it possible--while achieving the acoustic effect required--to realize a design weighing as little as possible, provided the resilient layer has a special shape on account of recesses and/or indentations, and/or knobs, fashioned on purpose.
