Thus, we have proposed a method to enable the simultaneous broadcasting of multiple voices by broadcasting inaudible sounds in addition to audible sounds and restoring them to audible sounds using a mobile device. However, in this method, impulsive noises are generated when the inaudible sounds are converted to audible sounds. In this paper, we investigated the cause of these impulsive noises and propose a method to reduce these noises.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告高度交通システムとスマートコミュニティ（ITS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2023-05-11","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"36","bibliographicVolumeNumber":"2023-ITS-93"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":225908,"links":{}}
