The latest research developments of the three key technologies of controller, actuator and sensor which are essential to the active noise and vibration control (ANVC) technologies are described in this paper. For the active structure acoustic control is becoming an important direction in the active noise control technology development, more is put on the active vibration control technology. From active vibration control and active noise control, the two aspects of ANVC technology, the application states of the ANVC technology in ship's noise and vibration reduction are also presented. According to the deficiencies of the passive noise and vibration reduction measures and the rapid developments of the active controlling technologies, the outlooks of applying the ANVC technologies to the submarines' noise and vibration controlling which with limited space and effective load are discussed. And the application occasions of ANVC technology in the future submarine acoustic stealth design are enumerated. So offer some references for improving the submarine's acoustic stealth performances. The end, the importance of the ANVC technology in improving the submarine's acoustic stealth level is put forward.
