This paper deals with an experimental study of active control of leakage-flow-induced vibrations. In order to stabilize leakage-flow-induced vibrations, this study proposed the new active feedback control method. The active vibration control is conducted by using a speaker as a control actuator for changing entrance pressure or exit pressure of passage. According to the experimental results, performance of the presented active control technique was clarified.
