What does bleep mean?
A bleep is a short, high-pitched electronic tone most familiar from radio and television, where it is used to mask profanity or other unsuitable language before broadcast. The word functions both as a noun, naming the tone itself, and as a verb meaning to cover speech with such a tone — as when a broadcaster 'bleeps out' a swear word. Beyond censorship, the term also describes similar electronic signals produced by machines, alarms, and medical equipment, giving it a broader technical use. Bleep emerged in the mid-twentieth century alongside modern audio technology and is generally considered imitative in origin, echoing the sound it describes. It carries a mildly informal, contemporary connotation and is closely associated with media regulation, so much so that the phrase 'bleep censor' has become standard vocabulary for describing the practice. Its near-synonym 'beep' covers general electronic tones, but bleep remains the go-to word specifically for censorship sounds.
A short high-pitched electronic tone, especially one inserted over offensive language in broadcast audio.
"Viewers heard a bleep where the guest's expletive had been."
Most often encountered in discussions of television and radio censorship.
To replace spoken words with an electronic censoring tone, or to make such a tone.

Standard plural; commonly used for sequences of censoring tones or machine signals.
"The heart monitor emitted steady bleeps throughout the night."
Before the 'bleep' existed, TV networks had no polite way to hide a swear word — now it's one of the most recognizable sounds in broadcasting.

Etymology of bleep
Bleep is a twentieth-century English coinage, generally regarded as imitative or echoic in origin, formed to mimic the actual sound of the short electronic tone it names. It appeared as audio broadcasting technology spread and networks needed a way to mask objectionable language, likely in the mid-1900s. The closely related word 'beep', formed in much the same way, developed around the same period, making the two words siblings rather than derivatives of a shared root.
