摘　　要：本文介绍了MTU16V396柴油机排气噪声的实船测试方法和谱分析结果，并对管内压力波和管口辐射噪声间的关系及其谱特性进行了初步分析。In this paper, a measurement scheme of exhaust noise from a marine diesel engine MTU16V396 under way is briefly described and some spectrum analysis results are given. Relationships between pressure wave in the exhaust pipe and noise rediated from the exhaust end as well as their speetrum characteristies are discussed
