针对船舶典型舾装复合结构，基于传递矩阵法构建声学性能分析模型，建立舾装复合结构隔声量及吸声系数分析方法，并通过声学试验验证了分析方法的可靠性。在此基础上，以某型水面舰船为例，探究了舾装复合结构对舱室噪声的影响规律。结果表明：基于传递矩阵法计算船舶舾装复合结构声学性能有效可行；敷设舾装复合结构后报务室和集控室降噪效果明显，分别达到2.2 dBA和2.5 dBA。
Aiming at the typical outfitting composite structure of ship, the acoustic performance analysis model is built based on transfer matrix method, and the analysis method of insertion loss and absorption coefficient of outfitting composite structure is established. The validity of the method is verified by experimental test. On this basis, the influence of outfitting composite structure on cabin noise characteristics is investigated based on a surface ship. The results show that the acoustic performance analysis method of outfitting composite structures based on transfer matrix method is effective. Outfitting composite structure can effectively control cabin noise,the noise level of radio room and centralized control room decreased by 2.2 dB(A) and 2.5 dB(A).
