In general, spacecraft are exposed to high acoustic pressure transmitted through payload fairings. Therefore, numerical prediction of vibroacoustic response with wide frequency range is quite important to design and develop reliable spacecraft and launch vehicles. Computational Fluid Dynamics (CFD) based on the finite volume methods etc. is sometimes used to predict unsteady acoustic environment with low frequency range at the launch site. As for steady-state vibroacoustic analysis in the low frequency range, the Finite Element Method (FEM) and Boundary Element Method (BEM) are often used. On the other hand, Statistical Energy Analysis (SEA) is applied in the high frequency range though it can provide only space- and frequency-averaged results. Therefore, there actually exists the mid-frequency range where we have no mature numerical methods. The authors focus on the Wave Based Method (WBM) which can produce detailed responses in steady-state vibroacoustic analysis for midfrequency range. In this paper, 2D WBM is applied to sound transmission analysis. We examine discontinuous boundary conditions and compute the sound transmission loss (TL) using a model of a simple experimental facility. Moreover, numerical predictions of TL by the WBM are compared with those by the FEM to verify the WBM.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064303015","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-08-009","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構研究開発本部"},{"subitem_text_value":"宇宙航空研究開発機構研究開発本部"},{"subitem_text_value":"宇宙航空研究開発機構研究開発本部"},{"subitem_text_value":"計算力学研究センター"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Aerospace Research and Development Directorate, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Aerospace Research and Development Directorate, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Aerospace Research and Development Directorate, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Research Center of Computational Mechanics"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"高橋, 孝"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"村上, 桂一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"青山, 剛史"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"金田, 英和"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takahashi, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Murakami, Keiichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Aoyama, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kaneda, Hidekazu","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-16"}],"displaytype":"detail","filename":"64303015.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"64303015.pdf","url":"https://jaxa.repo.nii.ac.jp/record/5417/files/64303015.pdf"},"version_id":"9e618f04-c034-4692-a074-164303c9167b"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"波動ベース法による音響透過解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"波動ベース法による音響透過解析"}]},"item_type_id":"5","owner":"1","path":["964","1541","1885","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"5417","relation_version_is_last":true,"title":["波動ベース法による音響透過解析"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:15:25.647533+00:00"}
