| Abstract: | Based on the VA One software platform,the effects to the sound absorption efficiency caused by density, porosity and thickness of the melamine foam are analyzed. And the selected sound-absorbing material is laid on a certain location of a 30-meter-class river patrol, then the simulation is compared,the goal of better acoustic noise reduction has been achieved. |
