The invention relates to a lightweight, sound-insulating lining (1) for a body part of a motor vehicle, especially in the form of a lightweight front wall lining, comprising a sound absorbing layer (1.1), a substantially air-tight sound damping layer (1.2) that is directly connected to the sound absorbing layer, and a foam layer (1.3) which adjoins the sound damping layer (1.2). The sound absorbing layer (1.1) is made of a porous absorber, preferably a fiber fleece or foamed plastic that has an air permeability ranging from 150 to 2,000 liters/m2s at a test pressure of 100 Pa. The sound damping layer (1.2) is made of an at least 0.5 mm thick, integral film layer of the foam layer (1.3) and is integrally joined to the porous absorber by foam-backing the porous absorber, essentially without foam penetrating therethrough. A method for producing such a lining is also disclosed.
