　　Passive control technology for noise reduction in fluid filled pipes is widely used.It can effectively attenuate the noise at high frequencies but with less effect on the low-frequency part.By researching on the waves as well as the vibration energy carried by each wave in the fluid filled pipes,the method of active piezo-electric control technology is employed for noise reduction.Finite element method ANSYS is chosen to analyze the noise reduction effect.The simulation results show that the equipment is extremely effective on controlling the lowfrequency noise.
