In the acoustic field of a duct fan, the rotating acoustic modes are generated due to the interaction of stators and rotating blades. To achieve the essential elimination of dominant acoustic modes inside the duct, the accurate acoustic mode decomposition and the reproduction of anti-noise are both required. We build a real-time acoustic mode decomposition system with an array of microphones circumferentially mounted on the duct surface. The filtered-x LMS algorithm in the frequency domain form is developed with applying the result of mode decomposition as an error signal in order to achieve the elimination of a specific acoustic mode. An array of loudspeakers is equipped circumferentially onto the duct to generate \"anti-noise\" signal. A large noise reduction and rapid convergence with this method have been shown by the results.","subitem_description_type":"Other"}]},"item_7_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: PA1420047000","subitem_description_type":"Other"}]},"item_7_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本機械学会(JSME)"}]},"item_7_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"The Japan Society of Mechanical Engineers (JSME)"}]},"item_7_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0387-5016","subitem_source_identifier_type":"ISSN"}]},"item_7_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00187441","subitem_source_identifier_type":"NCID"}]},"item_7_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構航空本部(JAXA)"},{"subitem_text_value":"九州大学"},{"subitem_text_value":"九州大学"},{"subitem_text_value":"宇宙航空研究開発機構航空本部(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構航空本部(JAXA)"},{"subitem_text_value":"九州大学"}]},"item_7_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Aeronautical Technology, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Kyushu University"},{"subitem_text_language":"en","subitem_text_value":"Kyushu University"},{"subitem_text_language":"en","subitem_text_value":"Institute of Aeronautical Technology, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Institute of Aeronautical Technology, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Kyushu University"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"長井, 健一郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"鈴木, 優太郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"猪口, 雄三"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"生沼, 秀司"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"石井, 達哉"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山崎, 伸彦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nagai, Kenichiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Suzuki, Yutaro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Inokchi, Yuzo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Oinuma, Hideshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ishii, Tatsuya","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamasaki, Nobuhiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Active Noise Cancellation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Fan Noise","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Duct Noise","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Mode Decomposition","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Filtered-x LMS Algorithm","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"モード解析を用いたダクトファンのアクティブ消音","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"モード解析を用いたダクトファンのアクティブ消音"}]},"item_type_id":"7","owner":"1","path":["1888"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"22494","relation_version_is_last":true,"title":["モード解析を用いたダクトファンのアクティブ消音"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:20:12.686574+00:00"}
