A sub-trope of NoisyShutUp.


[[HellIsThatNoise Gah! That sound!]]

But it got your attention, didn't it?

Seriously, there's no better way to arrest attention than to ''[=screeEEEEeeeeEEEEEeeEEEEEEEK!=]''

[shudder chill] ...no better way to arrest attention than to rake a nail or two across a blackboard. Usually works best with actual nails or a piece of chalk (especially a long, fresh piece), but some {{Badass Normal}}s can use their ''finger'' nails. In the absence of a chalkboard, a sharp object against glass produces a similar sound.


'''Will you STOP that!!!'''

[[HereComesTheScience Fun fact:]] certain schools of thought posit that the reaction to this sound is an atavistic response to when humanity's pre-evolved ancestors used a similar noise to warn each other of danger that should be fled from at once.

See also SinisterScrapingSound, a dangerous SisterTrope. Believe it or not, Wiki/{{Wikipedia}} actually has [[http://en.wikipedia.org/wiki/Sound_of_fingernails_scraping_chalkboard its own article]] about it.

* Invoked during a promo for [[Creator/DiscoveryChannel Shark Week]] in 2005. Several "town residents" were yelling questions about sharks when this scraping noise cut through the talk. Everyone turned to see [[Series/MythBusters Jamie Hyneman and Adam Savage]], that year's Shark Week hosts, plus a small blackboard that Jamie had just scratched.

[[folder: {{Anime}}]]
* ''Manga/GreatTeacherOnizuka''.
* It was also in ''Anime/ExcelSaga'', but done with a knife glove. Luckily for the audience, [[RelaxOVision the sound was replaced with music]].
* And ''Crossworlds''. Although that was on a stalagmite. It gains extra kudos for being weaponized -- the sound being used to disable a sharp-eared cat-person.
* ''Manga/OnePiece'' has it too. It's called Usopp Noise.
* ''Anime/FullMetalPanicFumoffu''. In the last episode Kaname does this to calm a CrowdPanic. She's badass enough that it works immediately.
* In ''Manga/DragonBall'', [[WeaksauceWeakness whistling]] has this effect on Namekians.
* In ''Manga/GAGeijutsukaArtDesignClass'', the main characters have been asked to retrieve an easel from the art room, which the art club has outfitted with a number of horror props. Namiko wants to get the object (though they've forgotten what it was), and leave, but Tomokane is determined not to be defeated in that way. Namiko has Miyabi stop her, and this is what she comes up with... to the displeasure of everyone else in the room.
* Butch and Cassidy do this to try and get Professor Oak to talk in a ''{{Anime/Pokemon}}Chronicles'' episode.

[[folder: ComicBooks]]
* The [[SadistTeacher French teacher]] from the French comic ''Les Profs'' does this while writing "Any attempt of ruckus, and I'll do it again".

* The laughter of the poltergeist girl in ''Fanfic/CalvinAndHobbesTheSeries'' is compared to this.

[[folder:Films -- Animated]]
* Weirdly and subtly used in the original short film ''WesternAnimation/{{Nine}}'', when the cat-beast has 9 cornered and rakes its claws across some nearby cement.
* In ''Disney/TheLionKing'', Scar scratches his claws on his cave wall, to the same type of sound.

[[folder:Films -- Live-Action]]
* Judge Doom in ''Film/WhoFramedRogerRabbit''. Since he wears gloves, he makes the noise with the chalk instead.
* Quint, making his legendary entrance in ''Film/{{Jaws}}''.
* And it was used in ''Film/ThePinkPantherStrikesAgain'' as CoolAndUnusualPunishment. The villain puts on a steel gauntlet from a suit of armor, grins at the tied-up female, walks to the slate blackboard, and -- [[DistantReactionShot CUT! to quite a distance away]], outside, and you STILL hear it. And her screaming.
* ''[[Film/SisterAct Sister Act 2: Back in the Habit]]'': Deloris does this to silence the loudly chattering, music-playing students in her music class. ''Twice''.
* The ''soundtrack'' of ''Film/TheDarkKnight'' somehow manages to incorporate this (fittingly, as the Joker's motif). [[http://www.youtube.com/watch?v=fB5tbTpQvsM Have a listen]].
* Freddy used this to torture Carlos in ''Film/FreddysDeadTheFinalNightmare'', as he stole his hearing aid, turned the volume up to 11, gave it back, made it unremovable and dragged his murder-glove all over a giant chalkboard. Then Carlos's head exploded.
* Inverted in ''Film/FinalDestination4'', where the salon scene contains some slightly unnerving shots of the pedicurist scraping a metal tool along the underside of a soon-to-be victim's ''toe''nail. The sound of the scraping is plainly heard, and unpleasant.
* The Grinch in the live-action ''Film/HowTheGrinchStoleChristmas'' reproduces this sound by scraping his nails/fingers along the side of a car.
* In ''Film/ErnestScaredStupid'', a young Ernest does this in a flashback before getting whacked in the head by his teacher.
* ''Film/TheQuickAndTheDead''. When the Lady is challenged to her first duel, her name is chalked up on a board with an audible screech that shows the tension she is feeling at that moment.
* ''Film/OutpostRiseOfTheSpetsnaz''. When the protagonist drags the Nazi nurse by her feet [[LaserGuidedKarma into her own testing chamber]], her nails scrape along the concrete floor.

* One ''Literature/{{Goosebumps}}'' short story features a summer school that punishes failing kids by making them go in a chalk closet to listen to this for all eternity.
* ''Literature/SeptimusHeap''
** ''Physik'' compares Queen Etheldredda's voice to this sound.
** According to ''Magyk'', Magogs enjoy this sound and make it in their freetime.

[[folder: LiveActionTV]]
* Invoked and PlayedForLaughs on ''Series/HappyEndings''-while Brad, Dave and Max are brainstorming in 'Bros Before Bros', Max interrupts and makes this noise himself-dragging his hand across a wooden pillar that couldn't possibly make the noise.
* An early Invention Exchange on ''Series/MysteryScienceTheater3000'' featured the [[MadScientist Mads']] "Chalk Man", a record player with a fake hand on the tonearm (with real human fingernails!) played against a chalkboard record in order to compel party guests to leave at 3 AM.
* Subverted and PlayedForLaughs on ''Series/{{Psych}}''. At one point, Shawn drags his fingernails down a ''whiteboard'' to get the attention of the people in the room. When it doesn't work (because whiteboards aren't made out of the right material to create the desired noise), he does it again while screeching into a microphone. Can be seen [[http://www.youtube.com/watch?v=FIlMb0RQuoM here]].
* ''Series/GameOfThrones''.
** In "The Sons of the Harpy", Lancel Lannister has the sign of the [[ChurchMilitant Faith Militant]] carved into his forehead upon joining their order, and the audience gets close-up shots of his nails painfully clutching the wooden table he's lying on (with sound effects, of course) just for added {{squick}}.
** In "Walk of Punishment", Tyrion Lannister deliberately scraps his chair while moving it into position at the Small Council table, just to troll his father Lord Tywin.

[[folder: Magazines]]
* In an 80's Cracked Magazine sendup about what would happen if the MoralGuardians forced the A-Team to be less violent, the A-Team is forced to use less violent methods of subduing the villains. It concludes with B.A. scraping his nails across a blackboard to make the kidnappers surrender.

[[folder: Music]]
* First thing heard in the opening title-track of Krabathor's ''Orthodox'' album is a long screech from a chalkboard before the riffs kick in.

[[folder: NewspaperComics]]
* ''ComicStrip/{{Garfield}}'':
** One [[http://images.ucomics.com/comics/ga/1990/ga900929.gif strip]] had Garfield threaten to do this near Jon so he would give him the last cup of coffee in the house.
** The logo box of [[http://images.ucomics.com/comics/ga/2000/ga000820.gif another strip]] shows Garfield and Odie standing in front of a blackboard with Garfield's name carved in it. Odie looks extremely unnerved, and one of Garfield's claws is sticking out.
** Yet another strip has Jon refuse to let Garfield into the house... until Garfield drags his claws down the window.

[[folder: ProfessionalWrestling]]
* Part of the theme music for WWE's Dean Douglas, also known as Wrestling/ShaneDouglas.

[[folder:Video Games]]
* In ''VideoGame/{{Disgaea 3|AbsenceOfJustice}}'', when you create a [[CatGirl Nekomata]] character, she will make her entrance by scraping her cat claws on the blackboard.
* Crops up twice in ''VisualNovel/PhoenixWrightAceAttorneyDualDestinies''. In Case 5-2, Athena comments that the scraping of rusty door hinges is this to her ultra-sensitive ears, and in Case 5-3 we get a more literal version of chalk scraping a chalkboard courtesy of Aristotle Means and his blackboard.

* ''Webcomic/WapsiSquare'' has this [[http://wapsisquare.com/comic/duck-and-cover/ in the shower]].

[[folder: WesternAnimation]]
* ''WesternAnimation/TheSimpsons'' has done this quite a few times -- one time featured Groundskeeper Willie doing it on a stained glass window, in a direct parody of Quint's use of the trope.
* In one episode of ''WesternAnimation/{{Arthur}}'', the title character daydreams that a villainous teacher is using the noise for torture rather than for straight attention-getting.
* On the Creator/TexAvery cartoon ''One Ham's Family'', when the villain is indisposed, the main character decides to [[NoFourthWall "heckle you folks out there"]] while he returns. So he takes out a chalkboard and a piece of chalk and screeches away.
* One ''WesternAnimation/SouthPark'' episode has Mr Garrison using a rusty nail to write on the chalkboard, because lawsuits have made chalk too expensive for the school.
** In another one, a couple of FBI agents do this to a balloon to force the boys to tell them where Starvin' Marvin is. Cartman gives in pretty soon.
* In ''WesternAnimation/AaahhRealMonsters'', a human kid disguised as a monster wins big points with the teacher for doing this.
* The ''Film/{{Jaws}}'' scene is also spoofed in the ''WesternAnimation/SpongebobSquarepants'' episode "Sandy, [=SpongeBob=] and the Worm". The character doing it just wanted to know where the bathroom was.
* ''WesternAnimation/TwoStupidDogs'' had this when Mr. H wrote his name on a chalkboard when he was substituting a class. It was ''excruciatingly'' long, and was enough to blow out the school's windows out. Just when the students think it's over, he adds a final ''scrEE!'' for the period.
* In an episode of ''WesternAnimation/TaleSpin'', Don Karnage puts on a Tiger's Claw glove and proceeds to rake it across a chalkboard to get his victim to talk.
* Alvin does this in the ''WesternAnimation/AlvinAndTheChipmunks'' episode ''The Brunch Club'' in order to get a confession out of Brittany.
* Used on ''WesternAnimation/TheAmazingWorldOfGumball'' to help him forget kissing his grandmother on the lips.
* Done in ''WesternAnimation/TheFairlyOddparents'' by Timmy as a prank. Since he is invisible at the time, everyone in the classroom thinks the chalkboard is haunted.
* In an episode of ''WesternAnimation/FamilyGuy'', Peter and Lois cover the couch with plastic wrap to protect it from Meg's nudist boyfriend. At one point, Peter rubs his hand against the plastic to annoy Lois with the screech.
* In one episode of ''WesternAnimation/MenInBlack'', the M.I.B. had to track down an alien whose voice was [[MakeMeWannaShout absolutely debilitating]]. Elle comes up with a noise-cancelling device that could counter the alien's ability, demonstrating by scratching her nails on a chalkboard without causing any cringing to the other agents.
* In the ''WesternAnimation/WeBareBears'' episode "Chloe", Ice Bear threatens to torture Chloe with a fork on a chalkboard for breaking into the Bears' house.
* In an episode of ''WesterAnimation/BobsBurgers'' parodying ''Film/{{Jaws}}'', Teddy drags his fingers across the board. He has to make the noise himself as he'd just clipped his nails.

[[folder: RealLife]]
* The 2004 Honda Civic's brake wear indicator ''was specifically designed to sound like this'' to force the owner to hit the workshop as soon as the brake pads were worn if only to get rid of that chilling, awful noise.
