However, it can be noticed in experiments that this method yields a systematic error in the absorption coefficient. The error is as a sinusoidal function of frequency, whose magnitude is a few percent of the absorption coefficient and whose frequency period corresponds to the wave length of two times the distance between the test piece surface and the microphone location for the reflection factor\nmeasurement.\nInvestigation of the cause for this phenomenon was carried out based on the Kirchhoff acoustic dissipation theory of the viscous and thermal boundary layer for wide tubes. Consequently it was found that the ISO correction method regards only the irreversible component and disregards the reversible component of the tube attenuation.\nA determination technique of the attenuation constant as a function of position is developed and implemented. The effectiveness of the position-dependent attenuation-constant in the twomicrophone-\nposition reflection-factor determination and in the tube-attenuation correction was\nevaluated by conducting BEM numerical simulations and experimental tests.","subitem_description_type":"Abstract"}]},"item_9_description_42":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_9_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"会議名称:The 35th International Congress and Exposition on Noise Control Engineering","subitem_description_type":"Other"},{"subitem_description":"主催学会:INCE/USA & INCE-Japan","subitem_description_type":"Other"}]},"item_9_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"INCE/USA & INCE-Japan"}]},"item_9_version_type_18":{"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":"寺尾, 道仁"}],"nameIdentifiers":[{"nameIdentifier":"7415","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Terao, Michihito"}],"nameIdentifiers":[{"nameIdentifier":"7416","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"石井, 孝憲"}],"nameIdentifiers":[{"nameIdentifier":"7417","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ishii, Takanori"}],"nameIdentifiers":[{"nameIdentifier":"7418","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"関根, 秀久"}],"nameIdentifiers":[{"nameIdentifier":"7419","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sekine, Hidehisa"}],"nameIdentifiers":[{"nameIdentifier":"7420","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"服部, 康章"}],"nameIdentifiers":[{"nameIdentifier":"7421","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hattori, Yasufumi"}],"nameIdentifiers":[{"nameIdentifier":"7422","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":"2018-11-16"}],"displaytype":"detail","filename":"21 inter･noise200612.pdf","filesize":[{"value":"769.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"21 inter･noise200612.pdf","url":"https://kanagawa-u.repo.nii.ac.jp/record/3207/files/21 inter･noise200612.pdf"},"version_id":"0019086b-7415-462c-9ca4-73a6f1d9df12"}]},"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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"A correction method of tube attenuation in impedance-tube two-microphone-position method for  absorption coefficient","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A correction method of tube attenuation in impedance-tube two-microphone-position method for  absorption coefficient"}]},"item_type_id":"9","owner":"1","path":["245"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-12-14"},"publish_date":"2010-12-14","publish_status":"0","recid":"3207","relation_version_is_last":true,"title":["A correction method of tube attenuation in impedance-tube two-microphone-position method for  absorption coefficient"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2025-02-12T02:56:56.260535+00:00"}
