空間上に存在する様々な方位や周波数帯域の音をヘッドフォン再生する際に，人の頭部運動を相殺する音源の相対的な提示位置の更新がどの程度遅延すると，人は違和感を覚えるのかを把握することは有用であると考えられる．我々は，頭部運動を模擬した音源をスピーカによって再生し，HRTF がスムーズに更新されたときを模擬した刺激音と，HRTF の更新が遅れたときの動作を模擬した刺激音を比較した．その結果，本実験での人の遅延検知限は 100ms ∼ 500ms 前後であり，帯域や音源の方位によって遅延の検知限が変化することが分かった．また，音源の移動速度による検知限の変化は見られなかった．","subitem_description_type":"Other"}]},"item_4_description_8":{"attribute_name":"論文抄録(英)","attribute_value_mlt":[{"subitem_description":"Technologies that enable the reproduction of highly realistic 3D audio fields are becoming increasingly important due to the recent proliferation of Virtual Reality (VR) or Augmented Reality (AR) applications. In order to transmit and reproduce 3D audio signals efficiently, it is crucial to understand the acceptable amount of delay in reproduced signals from headphones when a listener moves their head. We conducted a comparison between audio signals played back through loud-speakers simulating a smooth update of Head-Related Transfer Function (HRTF) and those simulating a delayed HRTF update. The test results show that the allowable delay time ranges from about 100 to 500 ms, depending on the bandwidth and azimuth of the signals. The movement speed of the audio signals did not affect the results.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告音声言語情報処理（SLP）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2024-02-22","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"79","bibliographicVolumeNumber":"2024-SLP-151"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":232549,"updated":"2025-01-19T10:24:39.235082+00:00","links":{}}
