摘　　要：某船舶大餐厅与机舱公用部分钢围壁导致餐厅噪声水平超标,严重影响船员就餐舒适性。基于统计能量分析法和经验分析法,对餐厅所在舱段进行声学仿真,通过对比数值计算结果与实测数据,分析餐厅噪声来源及组成,确定在外部控制振源,在内部敷设浮筑地板、吸隔声材料的综合治理方案,最终有效控制餐厅噪声。从工程实践角度为毗邻主要声源的船舶舱室噪声治理提供一种参考方法,并提出一些建议。In order to control the noise of the mess cabin exposed to the engine room on a ship,the acoustic simulation for the mess cabin is done based on statistical energy analysis(SEA)and empirical method.By comparing the numerical calculation results with the measured data,the noise source and composition of the mess room are analyzed.And the noise control plan is determined,including controlling the vibration source,laying the floating floor,sound absorption and insulation materials and so on.This study provides a reference for noise control of ship cabins exposed directly to noise sources.
