Bleep censor

A bleep censor is the replacement of a profanity or classified information with a beep sound (usually a About this sound 1000 Hz tone ) in television and radio.[1]


Censor boxes, such as the one above, may be used along with the bleeps so that the audience would not lip-read the swearer's words. Above, the cartoon says "Oh-", followed by the censor.

Bleeping has been used for many years as a means of censoring TV programs to remove content not deemed suitable for "family" or "daytime" viewing and personal information for privacy. The bleep censor is a software module, manually operated by a broadcast technician. A bleep is sometimes accompanied by a digital blur or box over the speaker's mouth in cases where the removed speech may still be easily understood by lip reading.

On closed caption subtitling, bleeped words are usually represented by the phrase "(bleep)", sometimes the phrase "[expletive]" or "[censored]", occasionally hyphens (e.g. f—k f---), and sometimes asterisks (e.g. ****, f***, f**k, f*ck, f#@k or f#@%), remaining faithful to the audio track. Where open captions are used (generally in instances where the speaker is not easily understood), a blank is used where the word is bleeped. Occasionally, bleeping is not reflected in the captions, allowing the unedited dialogue to be seen. Sometimes, a "black bar" can be seen for closed caption bleep.

Bleeping is normally only used in unscripted programs – documentaries, radio features, panel games etc. – since scripted drama and comedy are designed to suit the time of broadcast. In the case of comedies, most bleeping may be for humorous purposes, and other sound effects may be substituted for the bleep tone for comical effect, examples of which include a slide whistle, an infant's cooing, dolphin noises, or a spring "boing".

Other uses of bleep censoring may include reality television and daytime talk shows, where identifying information such as ages, surnames, addresses/hometowns, phone numbers and attempts to advertise a personal business without advanced or appropriate notice will be silenced or bleeped to maintain the subject's privacy (such as seen for subjects arrested in episodes of COPS).

When films are edited for daytime TV, broadcasters usually prefer not to bleep swearing, but cut out the segment containing it, replace the speech with different words, or cover it with silence or a sound effect. In the first example, the film may (unintentionally) become nonsensical or confusing if the removed portion contains an element important to the plot. The bleep is sometimes used for privacy reasons, concealing confidential information such as names and addresses. Bleep censors have seen a rare use in cinema film, for example during Johanna Mason's interview in The Hunger Games: Catching Fire, or during Tony Stark's meeting with Senator Stern in Iron Man 2.

Bleeping is commonly used in English-language and Japanese-language broadcasting, but is sometimes/rarely used in some other languages (such as Arabic, Chinese, Dutch, Icelandic, Filipino, French, German, Italian, Portuguese, Spanish, Polish, Russian, and Thai), displaying the varying attitudes between countries; some are more liberal towards swearing, less inclined to use strong profanities in front of a camera in the first place, or unwilling to censor. In the Philippines and Ecuador, undubbed movies on television have profanity muted instead of bleeped.
