A device for absorbing structure-borne sound comprises at least one torque transmitting flange having two or more layers of materials of different damping capacity and stiffness stacked on each other. At least a portion of the flange has a radially jagged cross-sectional profile including two or more flanks consecutively arranged in radial direction and alternately inclined to the radial direction. The consecutive flanks merge into each other by forming corners, respectively. This structure-borne sound absorber reduces the propagation of vibrations at acoustically relevant frequencies via rotating machine parts. Combination with a compensation coupling results in a high-elasticity coupling preventing noise radiation.
