摘要
以某新型海洋工程船为研究对象,采用基于统计能量法的自研软件建立船舶舱室噪声计算模型,舱室噪声计算结果表明该船舱室噪声满足MSC.337(91)《船上噪声等级规则》的船上噪声标准限值要求。本文所得计算结果对评估该船舱室噪声水平具有一定的参考价值。
Cabin noise on marine engineering vessel is evaluated in this paper. Based on statistical energy analysis theory,a numerical model is build to compute ship cabin noise. The evaluated results show that cabin noise in accommodation space is satisfied for noise limit requirement in MSC. 337( 91) 'Code on noise levels on board ships'. The achievement in this paper is valuable for cabin acoustic design of this marine engineering vessel.
