摘　　要：目前风关海洋环境噪声实验研究结果较多,其中较为经典的是Knudsen谱、Wenz谱、Piggott谱、Crouch谱,以及风速与噪声谱级的对数关系等。对这几种经典的海洋环境噪声谱进行了概述,分析了其数据来源,并对Wenz谱、Piggott谱和Crouch谱进行了比较,探究了其差异产生的原因,并给出了不同情况下进行风关海洋环境噪声估计时的参考建议。The very classic results of experimental studies of wind generated ocean ambient noises are Knudsen spectrum,Wenz spectrum,Piggott spectrum,Crouch spectrum and the logarithmic relationship between wind speed and noise spectrum level.This paper summarizes these four spectrums,analyses their experimental data sources,compares three of these classic spectrums and explores why the difference occurs.At last the suggestion is given about which spectrum is suitableto ambient noise evaluation in different situations.
