| description | The invention provides a marine multi-layer composite soundproof structure, comprising a front panel layer, a damping layer, an air layer, a sound-absorbing material layer, a light-steel keel and a back panel layer, wherein the parameter of the damping layer includes: the density is 22kg/m , the Young modulus is 46500N/m , the Poisson's ratio is 0.4, and the damping coefficient is 0.14. The marine multi-layer composite soundproof structure has good soundproof effect to low-frequency and medium and high frequency noises, especially to broadband noises sources, and accordingly has good military significance and social benefit.
本发明提供了种船用多层复合隔声结构，包括依次层叠的面板层、阻尼层、空气层、吸声材料层、轻钢龙骨、背板层；所述阻尼层采用聚氨酯，该阻尼层的参数为：密度22kg/m，杨氏模量46500N/m，泊松比0.4，阻尼系数0.14。本发明提供的船用多层复合隔声结构，可以有效地针对宽频带噪声源，对低频和中高频的噪声均具有较好的隔声效果，具有非常好的军事意义和社会效益。 |
