喋喋不休好逼瘋? 日研發神奇「彈話槍」成剋星

許多人講話時,只顧著自己喋喋不休,完全不考慮對方感受,近來有日本研究人員,研發出一種能讓人暫時閉嘴的「彈話槍」,透過這把槍可以將說話者的聲音「彈」回去,讓說話者因受干擾而無法繼續說話。

這把神奇彈話槍是由筑波市產業技術綜合研究所(National Institute of Advanced Industrial Science and Technology)的栗原一貴與御茶水女子大學的塚田浩二共同研發。他們以「延宕聽覺回饋」(Delayed Auditory Feedback,DAF)原理,將講者的聲音延遲0.2秒後彈回去,藉此干擾。

研究人員指出,彈話槍的效果取決於說話者的聲音大小、麥克風和喇叭接收與播放的增益大小而定。經科學家測試,像是演講者或是大聲唸報紙時,彈話槍的功能較顯著,若是「啊啊啊啊...」這種接連不斷的聲音,恐怕連彈話槍也幫不上忙。
