船舶辐射噪声的水平使得许多鱼类能够远距离检测到它们。船舶的噪声场在离散频率和总体水平方面极其动态，并且船舶之间的差异很大。该噪声场与鱼类的任何反应之间的关系可能很复杂，但目前没有足够的数据将特定观察结果与引起反应的船只的噪声特征相关联。本文精选了六艘研究船的数据来说明在各种运行和工作条件下遇到的可变性水平。概述了要解决鱼类对噪声的反应问题所需的噪声测量。
Levels of radiated noise from ships are such that many fish species are capable of detecting them at long ranges. A ship’s noise field is extremely dynamic in terms of discrete frequencies and overall level, and the variation from vessel to vessel is great. The relationship between this noise field and any reaction by fish may be complex, but currently there are insufficient data to correlate specific observations with noise characteristics of the vessels causing the reaction. A selection of data on six research vessels is presented to illustrate the levels of variability encountered under a variety of running and working conditions. An outline is given of the noise measurements required if the problem of fish reaction to noise is to be solved.
