Abstract

A muffler for structure-borne noise of running wheels of different diameters and/or different frequency spectrums of structure-borne sound vibrations has vibration absorbing elements in the form of members which are arranged next to one another in the circumferential direction, forming a circular disk, and are each connected on the base surface in a force-locking manner with the running wheel. The muffler for structure-borne noise consists of at least a first type of vibration absorbing elements which is always the same for a larger range of running wheel diameters, and at least a second type of vibration absorbing elements which is adapted to the respective running wheel diameter and frequency spectrum of structure-borne sound vibrations.
