Abstract
Acoustic signals emitted in the water include various information. A variety of noises due to marine vessels, biological, offshore plant construction, and breaking waves are included in underwater noise. Research on this area is also underway. Underwater noise is distributed in different bands in the frequency domain. Noise level of the frequency band is calculated to determine the noise source that affects the surrounding area. The ambient noise in the ocean is characterized by analyzing the isotropy noise level using one omnidirectional hydrophone. In this method, there is a limit to the characterizing of noise sources. However, if more than one hydrophone is used, the directional characteristics of the ambient noise can be identified. In this paper, horizontal directional underwater noise of ship traffic noise was analyzed in 200,400, 500, 800 Hz band using 20 hydrophone array.
