摘　　要：应用统计能量分析方法分析某船典型舱段舱室噪声,从船舶舱室噪声的传递途径入手,找到船舶舱室噪声主导传递途径、主导分量,开展典型舱室噪声综合预报,探索船舶典型舱室振动噪声的优化设计方案,在此基础上,提出典型舱室噪声的减振降噪措施。The typical cabin noise of a ship＇s subsection was studied by the statistical energy analysis （ SEA ） .By dealing with the transfer channels of the shipboard cabin noise , the dominant transfer channel and component were gotten .The compre-hensive prediction research on typical cabin noise was carried out to probe into optimization design schemes on vibration and noise of typical cabin .On the basis of this analysis , the measures of vibration and noise reduction in typical cabins were put forward .
