from 斯福外星電台 SIFU Alien Radio · host 回看工作室 Atelier Hui-Kan

作為自然界回音定位（echolocation system）的強手，蝙蝠透過反覆送出超高頻率的聲波、與接收聲波的回音，對周遭的物體加以定位與辨識，讓自己得以在黑暗環境的空中暢飛無阻，也透過同樣的技能捕食飛行中的蚊蟲。然而，即使像東亞家蝠這樣親近人類居住環境的蝙蝠物種，這通常發生在入夜時分半空中的熱鬧“音場”和狩獵場景，卻因為人耳聽不到超高頻聲音，以及牠們在昏暗中嬌小又一閃而過的身影，因而在人類耳中顯得異常安靜_即使當一位在入夜公園中閑坐者的頭頂上空，可能正有數隻蝙蝠在穿梭忙活。本段聲音發送，由四個小段串成：從人耳所聞，漸次進入到東亞家蝠尺寸和獨特聽覺世界的感知模擬中。一起來當一分鐘的東亞家蝠吧！第 1 分鐘：人類耳朵聽到的樹德公園一角第 2 分鐘：人類耳朵聽到的樹德公園一角+超音波錄音機捕捉的東亞家蝠第 3 分鐘：拿掉人的公園聲景，只留下超音波錄音，試著模擬從東亞家蝠角度可能會聽到的樹德公園空間。第 4 分鐘：再進一步吧 - 試著想像如果你縮小成一隻小小的東亞家蝠的體型，並進入牠的生命節奏，這時你所能感知到，從自己和周邊同類所發出並接收到的聲納訊息樣態。請留下您的回饋： https://open.firstory.me/user/clnsq5uxv00ky01u79fwpd6nf/comments Powered by Firstory Hosting
