随着国际海事组织对船上噪声控制要求的提高及强制规则的出台，船舶噪声级成为民船设计中需要重点关注的指标之一。为了满足船上噪声限值要求，声学设计工作需要纳入船舶设计流程中。文中针对船舶结构和噪声源的特点，在采用统计能量方法评估船舶声学设计效果的基础上，对不满足限值要求的舱室提出相应的控制措施，保证了该船舱室噪声满足MSC337的限值要求。大大提高了船舶声学设计的效率。

Onboard noise level is becoming one of the major design criteria of commercial ships in design stage as IMO proposed more rigorous requirements of onboard noise control, and, subsequent-ly, the enforcement of compulsory regulations was made. To meet the challenges due to the modifi-cations of the code on onboard noise, fast modeling strategy for cabin noise based on SEA is pro-posed and implemented. By employing the developed cabin noise software, the acoustic design of a large oil tanker in early stage is demonstrated, which shows that, compared to general commercial software, this cabin noise prediction platform is more efficient to help the engineers to make deci-sions on design modification and material selection.
