쇄파대에서 파도에 의해 발생된 주위잡음의 측정

Abstract

Underwater noise in the sea is used for monitoring wind speed and rainfall on the sea surface, as well as for tracking whale's migrating route. In particular, low-frequency ocean noise has recently been of concern with relation to the behavior of marine mammals. It is reported thatunderwater noise generated by breaking waves in the surf zone greatly contributes low-frequency ocean noise in coastal waters. And mechanismson underwater sound generation due to breaking waves in the surf zone have been studied by some researchers. Underwater ambient noise was measured to investigate the effect of the surf noise on the ocean noise in the eastern coastal waters of the middle part of the the Korean Peninsula. Themeasurements results on underwater noise generated by breaking waves in the surf zone are introduced. And we consider the effect of the surfnoise on the underwater ambient noise.
