| Abstract: | The application environment of hydrodynamic and low frequency noise attenuation techniques in naval vessel is analyzed at first in this paper, which points out the characteristics of sound propagation and excitation, requirements of safety and size in sea water piping system. Then, hydrodynamic and low frequency noise attenuation techniques, including traditional reactive silencer, gasbag silencer, elastic plate silencer and ANC, are analyzed in detail. The advantage and disadvantage of all kinds of these techniques is presented in this paper, which indicates the work to be carried out in the future. |
