船舶水管路噪声及其控制研究
The Liquid-born Noise and Its Control in Water Pipelines of Ships
【摘要】 分析了船舶水管路的主要噪声源及其控制方法,并用传递矩阵法计算了插入管式及内壁敷设吸声材料的扩张室式消声器的声学性能,计算结果表明可取得良好的消声效果。
【Abstract】 The liquid-born noise sources and the control measures in water pipelines of ships were introduced.The sound properties of the water muffler used in the experiments were calculated.Numerical results show that the water muffler has a good attenuation effects in wide frequency range.
