On the other hand, the attenuation characteristics can be calculated from the equivalent circuit of an acoustic system, if the four terminal constants of each section are known. Present work has been devoted to the determination of the four terminal constants, A, B, C and D of fundamental elements of acoustic filters [1]. The method and some results were reported. They are in considerable agreement with the theory. Attenuation of a combination filter was calculated also from measured A, B, C and D.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA2404806000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学航空研究所"}]},"item_9_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Aeronautical Research Institute, University of Tokyo"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0376-1061","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00514444","subitem_source_identifier_type":"NCID"}]},"item_9_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"National Institute of Industrial Health"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"MIWA, Toshisuke","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"IGARASHI, Juichi","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":"2020-01-24"}],"displaytype":"detail","filename":"SA2404806.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA2404806.pdf","url":"https://jaxa.repo.nii.ac.jp/record/34591/files/SA2404806.pdf"},"version_id":"27390d89-a7cd-46a7-a090-96103cc7c881"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"FUNDAMENTALS OF ACOUSTICAL SILENCERS : (II) Determination of four terminal constants of acoustical elements","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"FUNDAMENTALS OF ACOUSTICAL SILENCERS : (II) Determination of four terminal constants of acoustical elements","subitem_title_language":"en"}]},"item_type_id":"9","owner":"1","path":["1890","1901"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"34591","relation_version_is_last":true,"title":["FUNDAMENTALS OF ACOUSTICAL SILENCERS : (II) Determination of four terminal constants of acoustical elements"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T23:38:55.856869+00:00"}
