The system is regarded as equivalent to an electrical 2N-terminal network. In this case each terminal pair of the network corresponds to the one of the energy ports in the acoustical system. The steady state characteristics of the system are represented in the form of an acoustic impedance matrix which is analogous to an impedance matrix representation of the electrical 2N-terminal network described about. The mathematical treatment is based on the forced vibration solution of the steady state wave equation(Helmholtz equation). The relations between the acoustical impedance matrix and the Green function of the steady wave equation are discussed, and some formulas related to this point are obtained.","subitem_description_type":"Abstract"}]},"item_10_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_10_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"信州大学工学部紀要 7: 201-218 (1957)","subitem_description_type":"Other"}]},"item_10_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"信州大学工学部"}]},"item_10_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0037-3818","subitem_source_identifier_type":"ISSN"}]},"item_10_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00121228","subitem_source_identifier_type":"NCID"}]},"item_1627890569677":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"安田,  力","creatorNameLang":"ja"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-09-28"}],"displaytype":"detail","filename":"Engineering07-16.pdf","filesize":[{"value":"806.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Engineering07-16.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/13178/files/Engineering07-16.pdf"},"version_id":"d8d96497-2afd-4007-bbd7-a0e844c55561"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"音響系の電気回路網的特性表現","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"音響系の電気回路網的特性表現","subitem_title_language":"ja"},{"subitem_title":"Impedance Matrices Representations of Acoustical Systems","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["1300"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2011-01-05"},"publish_date":"2011-01-05","publish_status":"0","recid":"13178","relation_version_is_last":true,"title":["音響系の電気回路網的特性表現"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-03-16T05:54:56.617300+00:00"}
