“甬兴号”高速客轮的噪声研究

RESEARCH FOR NOISE OF HIGH-SPEED CATAMARAN"YONGXING

对航行于宁波与上海之间的“甬兴号”高速客轮的噪声进行测试和评价，找出主要噪声源并提出改进声环境的建议。提出了一种预估舱室内噪声级的计算方法和高速双体客轮噪声级限值标准的建议。

he noise level of high-speed catamaran Yongxing navigating between Ningbo and Shanghai was measured and evaluated. Based on this, The main noise sources were diagnosed and outline to improve the acoustic environment was proposed. A method was presented to estimate noise level in cabins and permissible noise level ofhigh-speed catamarans.
