Abstract

A system for actively attenuating acoustic vibrations of a rail for rail traffic is provided including at least one sensor for detecting at least a vertical acoustic vibration of the rail, at least one actuator for exciting at least a vertical counter-vibration of the rail and at least one control unit communicatively connected to the at least one sensor and the at least one actuator for controlling the at least one actuator depending on the vibration detected by the sensor, the counter-vibration being adapted to destructively interfere with the detected vibration, and the at least one actuator being mechanically coupled to the rail and to a carrier element supporting the rail. Also provided is a carrier element for the system and a method for actively attenuating acoustic vibrations of a rail for rail traffic.
