Abstract

A covering for lining acoustically excited surfaces includes an upper cover layer and a flush fitting lining that adheres to the rear side of the cover layer. The lining has sound deadening properties and is made of a plurality of lining modules. A method of manufacturing such a covering for acoustically excited surfaces includes the steps of forming a cover layer and lining the modules and applying the modules to the cover layer.
