Abstract
A damping material (11) in accordance with the invention consists of a ground material that is composed of fibers that are in loose connection with each other. For example, the fibers are minimally interlooped with each other or also glued to each other. This ground material is condensed in some areas in that the fibers are reoriented or interlooped with each other to a greater degree or glued to each other. Consequently, zones (17) and (18) of different densities are formed, thus making it possible to increase and adjust, as desired, the sound-damping effect of the damping material.
