The disclosure relates to an active vibration absorption system for absorbing the vibrations of a vibrating element. The vibration absorption system comprises a structure-borne sound exciter having a coupling element for coupling to the vibrating element and having an electrical coil for moving the coupling element by means of a coil current. The structure-borne sound exciter is designed to provide a measurement signal correlated with a detected induced voltage. Furthermore, the vibration absorption system comprises a control device, which is designed to identify a target current intensity of the coil current in accordance with the measurement signal and to control an actual current intensity of the coil current to the target current intensity. The target current intensity is designed to adjust the motion of the coupling element in such a way that the vibrations of the element are at least partly absorbed. Moreover, the control device is designed to identify a detection component and a control component from the measurement signal and to identify the target current intensity in accordance with the detection component.
