For damping the sound radiated as structure-borne or airborne noise in wheels, especially gear wheels having herringbone teeth which comprise a disc divided perpendicular to its axis and are assembled from two such parts, a uniform recess having an essentially right-angled cross-section is provided on each of the two mutually facing surfaces of the wheel parts, the walls of the recesses having a viscoelastic damping layer and a cover plate forced on.
