In this paper the dependence of sound propagation in a finite unflanged circular duct and sound radiation from the open end of a duct on duct length and sound frequency is discussed. The sound pressure at the central duct axis, amplitude and phase of the sound pressure at the open end, and the radiated sound pressure directivity were measured. From these values, the end correction, radiation impedance at the open end, and attenuation value were obtained and compared with similar values in other references. The experimental results were explained from the general theory of sound. As shown in table 1 the experimental values are much the same as in other papers and, in cases with different characteristics, they are similar.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_7_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"Kagoshima University","subitem_publisher_language":"en"}]},"item_7_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0451212X","subitem_source_identifier_type":"PISSN"}]},"item_7_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00040363","subitem_source_identifier_type":"NCID"}]},"item_7_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"424","subitem_subject_scheme":"NDC"}]},"item_7_version_type_14":{"attribute_name":"著者版フラグ","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":"柚木, 謙一","creatorNameLang":"ja"},{"creatorName":"YUNOKI, Kenichi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"川畑, 清忠","creatorNameLang":"ja"},{"creatorName":"KAWABATA, Kiyotada","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-28"}],"displaytype":"detail","filename":"AN00040363_v26_p1-7.pdf","filesize":[{"value":"794.6 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"AN00040363_v26_p1-7.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/7615/files/AN00040363_v26_p1-7.pdf"},"version_id":"d8014976-0d44-41ec-92ab-1bd539aa1b35"}]},"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":"有限長円形ダクトによる音波伝播と放射","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"有限長円形ダクトによる音波伝播と放射","subitem_title_language":"ja"},{"subitem_title":"Sound propagation and radiation of a finite circular duct","subitem_title_language":"en"}]},"item_type_id":"7","owner":"18","path":["36","5345"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-06-09"},"publish_date":"2015-06-09","publish_status":"0","recid":"7615","relation_version_is_last":true,"title":["有限長円形ダクトによる音波伝播と放射"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-02-20T05:01:12.920048+00:00"}
