考虑到两个主要的来源-表面搅拌和遥远的航运环境海洋噪声的数学描述。从表面搅动的贡献被证明是线性依赖于风速的对数，深度在400和2500英寻之间，在百慕大附近的几个地点。当考虑到这一点时，可以分析包括两个源的环境噪声数据，以确定源的各个水平。此外，两个源的标准偏差可以从测量水平的标准偏差确定。
A mathematical description of ambient sea noise is presented that takes into account the two dominant sources—surface agitation and distant shipping. The contribution from surface agitation is shown to be linearly dependent upon the logarithm of wind speed for depths between 400 and 2500 fathoms at several sites near Bermuda. When this is taken into account, the ambient‐noise data that include both sources can be analyzed to determine the individual levels of the sources. Also, the standard deviations of the two sources can be determined from the standard deviations of the measured levels.
