摘要
基于声环境影响评价软件CadnaA,参考船厂的平面布置图,进行了船厂的声环境模拟,得到了该船厂区域的等声级线图和部分敏感区域的噪声情况,并对船厂布局对声环境的影响进行了分析.对该船厂进行噪声测量,总结各种测量中需要解决的关键问题,探讨一种软件模拟预报和声学实地测量相结合的评价方法,这将为从技术角度给出噪声环境合理的控制措施提供参考.
Based on the sound environment impact assessment software CadnaA,referring to the layout plan of the shipyard and simulating the sound environment of the shipyard,the isoacoustic level diagram of the shipyard area and the noise situation of some sensitive areas are obtained.Then the impact of the shipyard layout on the sound environment is analyzed.In this paper,the noise measurement of the shipyard is carried out and the key problems that need to be solved in various measurements are summarized.An evaluation method combining software simulation prediction and acoustic field measurement is discussed.This will provide reference for the reasonable control measures of noise environment from the technical point of view.
