Localizing noise sources in the model test is therefore an important research subject along with measuring noise levels. In this paper, a noise localization method using a hydrophone array in a large cavitation tunnel is presented. The 45-channel hydrophone array was designed using a global optimization technique for noise measurement. A set of noise experiments was performed in the KRISO (Korea Research Institute of Ships &amp; Ocean Engineering) large cavitation tunnel using scaled models, including a ship with a single propeller, a ship with twin propellers and an underwater vehicle. The incoherent broadband processors defined based on the Bartlett and the minimum variance (MV) processors were applied to the measured data. The results of data analysis and localization are presented in the paper. Finally, it is shown that the mechanical noise, as well as the propeller noise can be successfully localized using the proposed localization method.<\/jats:p>","DOI":"10.3390\/rs8030195","type":"journal-article","created":{"date-parts":[[2016,2,29]],"date-time":"2016-02-29T10:55:59Z","timestamp":1456743359000},"page":"195","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Noise Localization Method for Model Tests in a Large Cavitation Tunnel Using a Hydrophone Array"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6749-3119","authenticated-orcid":false,"given":"Cheolsoo","family":"Park","sequence":"first","affiliation":[{"name":"Advanced Ship Research Division, Korea Research Institute of Ships &amp; Ocean Engineering, Daejeon 34103, Korea"}]},{"given":"Gun-Do","family":"Kim","sequence":"additional","affiliation":[{"name":"Advanced Ship Research Division, Korea Research Institute of Ships &amp; Ocean Engineering, Daejeon 34103, Korea"}]},{"given":"Young-Ha","family":"Park","sequence":"additional","affiliation":[{"name":"Advanced Ship Research Division, Korea Research Institute of Ships &amp; Ocean Engineering, Daejeon 34103, Korea"}]},{"given":"Keunhwa","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Defense Systems Engineering, Sejong University, Seoul 143-747, Korea"}]},{"given":"Woojae","family":"Seong","sequence":"additional","affiliation":[{"name":"Department of Naval Architecture and Ocean Engineering, Seoul National University, Seoul 151-744, Korea"}]}],"member":"1968","published-online":{"date-parts":[[2016,2,27]]},"reference":[{"key":"ref_1","unstructured":"Cavitation ITTC Committee (1978, January 15\u201323).
