Abstract

The invention relates to a method for reducing sound transmission in vehicles, particularly in rail vehicles, to an undercarriage for vehicles, particularly for rail vehicles, and to an actuator. The invention is suited for, but not limited to, use in rail vehicles for passenger transit, particularly for rapid long-distance traffic. According to the method for reducing sound transmission in rail vehicles, at least one vibration sensor (1) senses the disturbing vibrations generated and/or transmitted by the wheels. A device for analyzing the frequencies of the signals of the least one vibration sensor (1) determines the frequencies of the strongest harmonic excitations. At least one fault sensor (2) measures the residual vibrations or residual forces transmitted to the secondary level (14) or to the car body. In the event disturbance frequencies are determined by the device for analyzing the frequency of the vibration sensor signal, a control unit generates the control signals for at least one actuator, especially a piezo-actuator (3) while taking the signals of the at least one fault sensor (1) into account. The at least one actuator, particularly piezo-actuator, minimizes the residual vibrations or residual forces transmitted to the secondary level (14) or to the car body.
