is Sound Source Localization (SSL) technology? Sound Source Localization technology means using multiple microphones at different points in the environment, and measuring the acoustic signal. The sound arrives at the microphones at different times. An algorithm is applied to process the received acoustic signal, thus gaining the relative direction (including azimuth and pitching angle), distance, and other information of the source point. Human Ear Localization When it comes to sound source localization, it is easy to think of how the human ears work. Human ears have monaural and bilateral localization ability. In the case of monaural localization, the received sound wave is reflected by various parts of the auricle&hellip;&nbsp;<a href=\"https:\/\/www.lansitec.com\/ja\/blogs\/\u97f3\u6e90\u5b9a\u4f4d\u306f\u3069\u306e\u3088\u3046\u306b\u6a5f\u80fd\u3059\u308b\u306e\u304b\/\" rel=\"bookmark\">\u7d9a\u304d\u3092\u8aad\u3080 \u00bb<span class=\"screen-reader-text\">\u97f3\u6e90\u5b9a\u4f4d\u306e\u4ed5\u7d44\u307f<\/span><\/a><\/p>","protected":false},"author":1,"featured_media":16171,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"neve_meta_sidebar":"","neve_meta_container":"","neve_meta_enable_content_width":"","neve_meta_content_width":0,"neve_meta_title_alignment":"","neve_meta_author_avatar":"","neve_post_elements_order":"","neve_meta_disable_header":"","neve_meta_disable_footer":"","neve_meta_disable_title":"","footnotes":""},"categories":[268],"tags":[33,34,269,29,43,16,120,87],"class_list":["post-16133","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-iot-faqs","tag-bluetooth-iot-technology","tag-bluetooth-technology","tag-indoor-positioning-technologies","tag-iot-technology","tag-lora-technology","tag-technology","tag-uwb-technology","tag-whitepaper-bluetooth-technology"],"_links":{"self":[{"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/posts\/16133","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/comments?post=16133"}],"version-history":[{"count":0,"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/posts\/16133\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/media\/16171"}],"wp:attachment":[{"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/media?parent=16133"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/categories?post=16133"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.lansitec.com\/ja\/wp-json\/wp\/v2\/tags?post=16133"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
