Then, using the boundary element method, we solved the sound propagation problem where a plane wave in a fixed direction comes to this model placed in 3-dimensional free space. It was observed that the sound frequency responses near left and right external ears vary drastically according to the changes in incident direction and/or boundary conditions on the ear.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"9","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告ハイパフォーマンスコンピューティング（HPC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"1991-03-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"26(1990-HPC-036)","bibliographicVolumeNumber":"1991"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"created":"2025-01-18T22:59:43.765104+00:00","id":30032,"links":{}}
