However, no tuning device or general-use system is yet available, and engineers have thus been avoiding the use of such resonators. The objective of this study is to develop a tuning system for resonator arrays for HVAC ducts. We employed the cavity volume, resonator neck resistance\nand neck open area as control parameters to tune the resonance frequency, resonance\nsharpness and sound dissipation factor, respectively. To control the cavity volume,\nresistance and neck open area, respectively, a cylinder with a screwed shaft, a spiral spring with adjustable gaps between the spring plates, and a camera aperture were used. These were controlled by individual stepper motors, which were driven by signals supplied by a PC.\nAn experimental resonator array tuning system composed of six prototype tuning devices was build and installed in a section of a 250-mm diameter duct. The eighteen parameters of the six resonators were tuned successively through a feedback approach allowing the transmitted traveling plane wave to reach its target spectrum with reasonable precision.\nWhen a resonator tuner was inactive at its target resonance frequency, this target resonance frequency was switched to that of the next inactive tuner.","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 39th International Congress and Exposition on Noise Control Engineering","subitem_description_type":"Other"},{"subitem_description":"主催学会:SPA & SEA","subitem_description_type":"Other"}]},"item_9_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"SPA & SEA"}]},"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":"7423","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Terao, Michihito"}],"nameIdentifiers":[{"nameIdentifier":"7424","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"関根, 秀久"}],"nameIdentifiers":[{"nameIdentifier":"7425","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sekine, Hidehisa"}],"nameIdentifiers":[{"nameIdentifier":"7426","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鈴木, 誠人"}],"nameIdentifiers":[{"nameIdentifier":"7427","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Suzuki, Masato"}],"nameIdentifiers":[{"nameIdentifier":"7428","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":"23 InterNoise2010.pdf","filesize":[{"value":"3.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"23 InterNoise2010.pdf","url":"https://kanagawa-u.repo.nii.ac.jp/record/3208/files/23 InterNoise2010.pdf"},"version_id":"bc238955-1496-4a35-8a85-24a8131c861f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Helmholtz resonator","subitem_subject_scheme":"Other"},{"subitem_subject":"tuning device","subitem_subject_scheme":"Other"},{"subitem_subject":"spiral spring","subitem_subject_scheme":"Other"},{"subitem_subject":"HVAC duct","subitem_subject_scheme":"Other"}]},"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":"IMPLEMENTATION OF A TUNING SYSTEM FOR HELMHOLTZ RESONATOR ARRAYS IN A HVAC DUCT","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"IMPLEMENTATION OF A TUNING SYSTEM FOR HELMHOLTZ RESONATOR ARRAYS IN A HVAC DUCT"}]},"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":"3208","relation_version_is_last":true,"title":["IMPLEMENTATION OF A TUNING SYSTEM FOR HELMHOLTZ RESONATOR ARRAYS IN A HVAC DUCT"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2025-02-12T02:56:56.457974+00:00"}
