Analytically, they can be obtained by calculating from the equivalent circuits and the method of measurement of the four-terminal constants of the black boxes was reported in Part II [2]. The present paper includes the method of measuring the attenuation characteristics by the electric simulator. Several acoustic elements were simulated by the electric elements and the results obtained agreed well to those by the acoustic method. Without constructing any real models of the silencers we can get the attenuation characteristics by proper selection of the electric elements. Effect of length of the pipe which connects the engine and the muffler was also studied by this method.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA2404827000","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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"IGARASHI, Juichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ARAI, Masaaki","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":"SA2404827.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA2404827.pdf","url":"https://jaxa.repo.nii.ac.jp/record/34598/files/SA2404827.pdf"},"version_id":"97efb892-a3a8-4b59-bd94-a9f7462462d8"}]},"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 (III) Attenuation characteristics studied by an electric simulator","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"FUNDAMENTALS OF ACOUSTICAL SILENCERS (III) Attenuation characteristics studied by an electric simulator","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":"34598","relation_version_is_last":true,"title":["FUNDAMENTALS OF ACOUSTICAL SILENCERS (III) Attenuation characteristics studied by an electric simulator"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T23:38:48.770178+00:00"}
