基于统计能量法建立海洋平台舱室噪声预报模型,并将实验测试获取的内损耗因子作为参数输入,探索了海洋平台舱室的噪声特性规律,对超标舱室进行主导传递途径和主导分量分析,给出舱室噪声超标的原因,并提出声学优化措施。研究表明,除广播室及医务室外,其他平台舱室噪声均满足限值要求,且广播室及医务室噪声超标主要由局部噪声源引起,敷设高隔音复合岩棉板可有效降低舱室噪声,使平台舱室噪声满足限值要求。
Based on the statistical energy method, the noise prediction model of offshore platform cabin is established, and the internal loss factor obtained from the experimental test is taken as the parameter input, and the noise characteristics of offshore platform cabin are explored. Based on the analysis of the dominant transmission path and the dominant component of the cabin exceeding the standard, the causes of the noise exceeding the standard of the cabin are given, and the acoustic optimization measures are put forward. The results show that all the compartments except the broadcasting room and the medical outdoor room meet the noise limit requirements, and the high sound insulation composite rock cotton plate plays a significant role in reducing the cabin noise and ensuring that the platform cabin noise meets the limit requirements.
