针对船舶舱室噪声控制问题，开展声学材料表面铺层对船舶舱室噪声控制效果的影响研究。首先，基于传递矩阵方法建立声学材料微观声学性能分析模型，分析典型舾装声学材料吸隔声性能参数，并将理论计算结果与阻抗管试验值进行了对比，验证理论分析方法的有效性；其次，基于本文方法开展不同表面铺层对声学材料微观声学性能的影响研究，总结船舶舾装声学材料不同表面铺层吸隔声特性规律。最后，以某船舶实尺度舱室噪声测试值为基准，采用统计能量法探究考虑声学材料表面铺层与否对船舶舱室噪声的影响。研究表明，传递矩阵法可用于船舶舾装声学材料微观声学性能分析，表面铺层的存在将改变声学材料微观声学性能，并进一步影响船舶舱室噪声控制水平。
Aiming at the problem of effective control of ship cabin noise, the influence of acoustic material surface layer on ship cabin noise control effect is studied. Firstly, the micro acoustic performance analysis model of marine outfitting materials is established based on the transfer matrix method, and the absorption and sound insulation performance parameters of typical outfitting materials are analyzed, and the theoretical calculation results are compared with the impedance tube test values to verify the effectiveness of the theoretical analysis method; secondly, the influence of different surface layers on the micro acoustic performance of outfitting materials is studied based on this method Finally, based on the noise test data of a ship's real cabin, the influence of different surface layers of outfitting materials on the noise of ship's cabin is explored by using statistical energy method. The results show that the transfer matrix method can be used to analyze the micro acoustic performance of ship outfitting materials. The existence of surface layer will change the micro acoustic performance of outfitting materials and further affect the noise control level of ship cabin.
