해앙에서 강우에 의하여 발생된 수중잡음의 특성을 밝히기 위하여 한국 동해의 연안에서 비가 내리는 동안 해수중 주위잡음을 측정하였다. 수심 200 m인 정점에서 세 개의 수중청음기를 각각 수심 30 m, 50 m및 100 m에 설치하였다. 먼저 강우상도가 1.5~23.4 mm/h일 때 강우잡음의 스펙트럼 특성을 주의깊게 조사하였다. 그리고 다양한 주파수에 있어서 스펙트럼레벨과 강우강도와의 관련을 조사하였다. 또한, 수중청음기로 수신한 강우잡음의 파형을 관찰하여 강우에 의한 수중잡음의 발생기구에 대하여 고찰하였다.

In order to investigate the characteristics of oceanic rain noise, we measured ambient noise at a site on the east coast of the Korean Peninsula while it rained. Three hydrophones were placed at a depth of 30 m, 50 m, and 100 m respectively where the water depth was 200 m. The spectral characteristics of rain noise were carefully examined according to rainfall rates between 1.5 and 23.4 mm/h. And the dependence of spectral level on rainfall rate was investigated for various frequencies. Also, it was considered the generation mechanism of rain noise by means of observation of rain noise waveforms received by hydrophone.
