The circular slit resonator composed of thin air layer that is radial expansion with very short axial length was set up package wall. The circular thin air layer is driven by one to four speakers that are controlled using Filtered-X-LMS algorithm to minimize sound power at error microphone. The experimental results show that the noise reduction region spreads to the high frequency side, as the slit depth decreases. The noise reduction quantity increases, as the slit width widens. Visualization of SPL and phase on the circular slit resonator indicate that the noise reduction mechanism is the interference of control sound and noise.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"45398","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Watanabe, Seiji"}]},{"nameIdentifiers":[{"nameIdentifier":"45399","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yanagimoto, Kensaku"}]},{"nameIdentifiers":[{"nameIdentifier":"45400","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Tanifuji, Katsuya"}]},{"nameIdentifiers":[{"nameIdentifier":"45401","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Sakamoto, Syuhichi"}]},{"nameIdentifiers":[{"nameIdentifier":"45402","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Itoh, Takahiro"}]},{"nameIdentifiers":[{"nameIdentifier":"45403","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Ichimiya, Ryohichi"}]}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本機械学会"}]},"item_5_relation_31":{"attribute_name":"異版である","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110002378732","subitem_relation_type_select":"URI"}}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本機械学会"},{"subitem_rights":"本文データは学会の許諾に基づくCiNiiからの複製である"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00187463","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03875024","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"渡部, 誠二"}],"nameIdentifiers":[{"nameIdentifier":"45392","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"柳本, 憲作"}],"nameIdentifiers":[{"nameIdentifier":"45393","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"谷藤, 克也"}],"nameIdentifiers":[{"nameIdentifier":"45394","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"坂本, 秀一"}],"nameIdentifiers":[{"nameIdentifier":"45395","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"伊藤, 孝宏"}],"nameIdentifiers":[{"nameIdentifier":"45396","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"一宮, 亮一"}],"nameIdentifiers":[{"nameIdentifier":"45397","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-07-30"}],"displaytype":"detail","filename":"9_0163.pdf","filesize":[{"value":"616.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"9_0163.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/3790/files/9_0163.pdf"},"version_id":"8259c3e1-682b-4bef-ac56-a70cd8247f28"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Machine Tool","subitem_subject_scheme":"Other"},{"subitem_subject":"Noise","subitem_subject_scheme":"Other"},{"subitem_subject":"Noise Control","subitem_subject_scheme":"Other"},{"subitem_subject":"Active Noise Control","subitem_subject_scheme":"Other"},{"subitem_subject":"Circular Slit Resonator","subitem_subject_scheme":"Other"},{"subitem_subject":"Filtered-XLMS","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":"円形空気薄膜層を壁面内に有する機械開口部からの音響放射（能動型分布音源による消音特性）","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"円形空気薄膜層を壁面内に有する機械開口部からの音響放射（能動型分布音源による消音特性）"},{"subitem_title":"円形空気薄膜層を壁面内に有する機械開口部からの音響放射（能動型分布音源による消音特性）","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","425"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-04-08"},"publish_date":"2008-04-08","publish_status":"0","recid":"3790","relation_version_is_last":true,"title":["円形空気薄膜層を壁面内に有する機械開口部からの音響放射（能動型分布音源による消音特性）"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:36:51.908522+00:00"}
