外刊例句
Back in the lab, the researchers paired off their collected specimens and each toad was allowed to capture and swallow a single beetle. And then came the fireworks. As the authors note in their paper: “an explosion was audible inside each toad.” Which means that somewhere along the alimentary canal, the beetles dropped their bombs.
回到实验室,研究人员将收集到的标本配对,每只蟾蜍可以捕获并吞下一只甲虫。然后烟花就来了。作者在论文中写道:“每只蟾蜍体内都能听到爆炸声”。这意味着甲虫在消化道的某个地方扔下了炸弹。

基本释义
audible:A sound that is audible is loud enough to be heard.
adj. 听得见的
追根溯源
单词audible里的词根audi来自拉丁语audiō,表示“听”,所以,在英语里包含audi的单词,多与此相关。例如:
audio /??di??/ adj. 声音的
audience /???di?ns/ n. 听众,观众
audition /???d??n/ n. 试听,试演
auditorium /???d??t??ri?m/ n. 礼堂;讲堂
后缀ble表示形容词,表示“可被...的”,所以,audi+ble=可被听见的
