Description
Summary:The objective of this report is to provide information on deep ocean ambient noise which can be used in sonar system design and analysis. Guidelines are given for estimating wind-generated noise, oceanic ship traffic noise, biological noise levels, and the composite ambient noise background. The report also discusses recent measurements and studies on the directional properties of noise, and on the space-time correlations. Early and recent reports on ambient ocean noise are reviewed and evaluated. Some conclusions are drawn on the variability of reported noise levels in the northwest Atlantic area and on the correlation of wind speed with respect to noise. (Author)
