那一聲本身
這一支就是核心畫面本身：聲音，以及發出聲音這個動作。
noun · B2
A short, high sound made by a piece of electronic equipment — the kind of sound a microwave, a timer, a card reader or a phone makes. One sound is one bleep, and a machine can give several in a row.
嗶聲
核心畫面
One way to hold this word: everything starts from one short, high sound a machine makes. From there English lets the sound spread in three directions. It becomes the action — the machine bleeps. It becomes the box that makes it, the little device a doctor carries. And because that sound is what television puts over swearing, it becomes the cover for a rude word, and then the stand-in for the word itself. Even the music named bleep is just that sound, played on purpose for an hour.

可以想成：這個字的一切都從機器發出的那一聲短短高高的「嗶」開始。從那一聲出發，英文讓它往三個方向長。它變成動作——機器在嗶。它變成發出聲音的那個小盒子，也就是醫生帶在身上的呼叫器。又因為電視上就是用這一聲蓋住髒話，它接著變成髒話的遮罩，最後連那個被遮住的字本身都叫 bleep。連那種被叫做 bleep 的音樂，說穿了也只是同一種聲音，被人刻意放上一個小時。From the word’s history
Wiktionary gives the origin as simply onomatopoeic: the word copies the sound. That is why the core image and the word are the same thing — saying bleep is making a small version of the noise.
Wiktionary 對這個字的說明只有一個詞：擬聲（onomatopoeic），也就是用發音模仿那個聲音。所以這裡的核心畫面跟字本身其實是同一件事——唸出 bleep，就等於把那一聲小小地重演一次。
