Abstract
An ambient noise level in the ocean is important parameter to enhance passive sonar detection performance. It is also significant parameter to design undersea surveillance system in harbor. For this reason, many researchers have measured and analyzed ambient noise in the ocean during a few decades. From these studies, it is well known that the primary sources of ambient noise in the deep ocean are distant shipping and ocean surface wind and they in the coastal ocean are the breaking waves and marine life as well as the shipping and wind. However, an ambiguity in acoustic interpretation of the observed ambient noise in the ocean still exists. In this study, weinvestigated depth dependence of ambient noise levels at low frequency range in the eastern sea ofKorea.d analyzed ambient noise in the ocean during a few decades.
