Examples of HellIsThatNoise from Live-Action TV, where a sound terrifies the characters because they know something dangerous is nearby.
----
* ''Series/AnotherPeriod'': Ditzy heiress Beatrice Bellacourt is variously called upon to feign grief or sing; in both cases, the most she can muster is a bizarre squawk.
* ''Series/BabylonFive'': The sound of a [[EldritchStarship Shadow vessel]]. They like to scream telepathically into the minds of their prey, to add terror to their attacks. As though their cleave beams which can split most ships in half with one shot ''need'' added terror.
* ''Series/BattleBots'': The sound that Minotaur's drum spinner makes as it spins up. The commentators compare it to to a jet engine, but the truly terrifying part is that it keeps getting louder... and the louder it is, the more destructive it is.
* ''Series/{{Chernobyl}}'': The ticking of a Geiger counter, especially in the really irradiated areas where it's almost a constant drone.
* ''Series/DoctorWho'' has a few, especially due to the "screaming companion" effect, and Steven Moffat's philosophy of "''Doctor Who'' takes place ''under your bed, in the dark''.":
** Those who aren't familiar with the noises the TARDIS makes might be freaked out when they hear a ship take off with a sound like a large animal dying of respiratory failure. However, because that noise is generally synonymous with the Doctor arriving to fix things, it has become a SugarWiki/MostWonderfulSound for most of the universe.
*** In the console rooms used in the original 1963-89 run, the ambience within the TARDIS was a gentle, high-pitched humming. In the 2005-10 version of the console room, it's a low pulsing noise that sounds like the TARDIS is ''breathing.''
*** The Cloister Bell: a low, echoing distorted bell tolling, informing the TARDIS's occupants that the ship is in some form of critical danger. It's essentially OhCrap in audio form.
*** The TARDIS going out of control at the end of "[[Recap/DoctorWhoS1E2TheDaleks The Daleks]]" and the beginning of "[[Recap/DoctorWhoS1E3TheEdgeOfDestruction The Edge of Destruction]]"; a sudden low-pitched explosion, followed by a painfully slow grinding of the TARDIS's engines... then a series of repeating, high pitched tones.
** "'''[[CharacterCatchphrase EXTERMINATE!]]'''" If you hear a Dalek say this, there's a good chance you're not going to survive. It's no wonder the Doctor was horrified when he found out that Daleks managed to survive the Time War. Used to its most terrifying effect in "[[Recap/DoctorWhoS30E12TheStolenEarth The Stolen Earth]]", where it's broadcast by [[spoiler:''thousands of alien ships invading Earth'']]. Anyone having any idea what the broadcast means is terrified beyond sense, with one character declaring "There's nothing we can do. I'm sorry, we are dead."
*** Dalek ships often have an electronic ambience that sounds all too much like a distorted heartbeat.
** The classic series made use of electronic music more prominently than the revived series, resulting in many such moments.
*** One of the most famous times this happened is right there in the [[Recap/DoctorWhoS1E2TheDaleks very second story]], which introduces the Daleks ([[ExactlyWhatItSaysOnTheTin as if that won't be obvious enough]]). The reveal of the Doctor's new nemeses is accompanied by [[https://www.youtube.com/watch?v=fB2XgLUa8f8 sliding, metallic walls of sound, and a high-pitched electronic screech]].
*** "[[Recap/DoctorWhoS4E5TheUnderwaterMenace The Underwater Menace]]" has the first primarily electronic soundtrack in the whole of ''Doctor Who'', an incredibly unsettling score made up of OminousLatinChanting, eerie church-organ-like music and sudden distorted tape samples. This was in 1967, when such things were at the cutting age and still alien to most listeners.
** Often even the ''theme music'' can apply -- the 1963-80 and the 2018-onwards arrangements feature an ominous hissing loop, and the famous "electronic scream" that punctuated many a cliffhanger has been part of the show since the 1970s.
** "[[Recap/DoctorWhoS27E9TheEmptyChild The Empty Child]]"/"[[Recap/DoctorWhoS27E10TheDoctorDances The Doctor Dances]]": The characters become terrified of a little boy asking, "Are you my mummy?", because very soon, [[ViralTransformation they will, too]]!
** "[[Recap/DoctorWhoS30E17E18TheEndOfTime The End of Time]]": There's a pattern of beats that creeps out even the Doctor. "dat-dat-dat—DAT". The sound of the Master. [[spoiler:It gets ''really'' complicated, too. That sound is coming from inside the Master's head, from when he looked into the Vortex of Time-Space. That sound of knocking also heralds the death of the Tenth Doctor. Plus, the Master's drumbeat was in the theme tune from the very first episode of ''Doctor Who''.[[note]][[http://www.dailymotion.com/video/xyms9l_an-unearthly-child-1-an-unearthly-child_shortfilms Proof:]][[/note]]]]
** "[[Recap/DoctorWhoS31E5FleshAndStone Flesh and Stone]]": The horrific screeching sound that passes for the Weeping Angels' [[EvilLaugh laughter]].
* ''Series/FamilyMatters'': {{Parodied|Trope}} in "The Good, the Bad, and the Urkel". Carl punches Steve's father over a dispute about his compost heap and Steve vows revenge. Carl then slips into a DreamSequence while watching a Western. He dreams that the dispute happens in the Old West. Inside the saloon, ominous background music continuously plays after dramatic lines, causing everyone in the saloon to look around for the source. After a final toot of the brass section when Steve challenges Carl to a duel, he says that before the duel happens, they have to form a posse to "track down that dang orchestra."
* In an episode of ''Series/{{Frasier}}'', Frasier makes friends with a man named Bob, who is in a wheelchair. Bob turns out to be both the most boring friend alive and a StalkerWithoutACrush. The wheels on his chair squeak horribly, leading Frasier to dive behind the board to hide from him.
* ''Series/{{Friends}}'':
** An in-universe example: Chandler flinches every time he hears "[[{{Catchphrase}} OH. MY. GOD!]]" and realizes that he's run into Janice ''again''.
** Ross's "sound", his term for the discordant music he plays on his keyboard, which everybody except Phoebe hates, in "[[Recap/FriendsS4E7TheOneWhereChandlerCrossesTheLine The One Where Chandler Crosses The Line]]":
--->'''Rachel:''' Oh, I can't believe I ever let him touch me with those fingers.
* ''Series/GameOfThrones'':
** In Season 3, The Boy's ColdBloodedTorture of [[spoiler:Theon Greyjoy]] includes [[{{Troll}} blowing an unpleasant-sounding horn]], slowly driving the victim mad.
** The screech of the White Walkers.
** Likewise, the sound of attacking wights. Probably the best way to describe them would be to compare them to snarls of an animal recreated by crunching bones against each other.
** The Bastard's Girls' barks sound downright demonic.
** [[https://youtu.be/f67yAq5t5xc?t=1m48s The captured Wights' screech in Beyond The Wall is repulsive.]]
* ''Series/ItsAlwaysSunnyInPhiladelphia'': Dennis' DaydreamSurprise in "[[Recap/ItsAlwaysSunnyInPhiladelphiaS11E05MacAndDennisMoveToTheSuburbs Mac and Dennis Move to the Suburbs]]". After Wally tells Dennis about the weather, Dennis [[FullFrontalAssault strips nude]] and threatens to punch Wally so hard his heart stops. The noise that comes out of his mouth following this threat is nothing short of absolutely DEMONIC.
* ''Series/KamenRiderRyuki'': Every reflective surface is a gateway to the Mirror World; an alternate dimension where bloodthirsty monsters live. Whenever such a monster preys on a human, a distinct shrill whistling sound can be heard, indicating it is about to attack. It seems only Riders are able to hear the sound.
* ''Series/Legion2017'':
** The appearance of the Devil with Yellow Eyes is always accompanied by a frantic-sounding warbling trumpet noise, and sometimes by a low-pitched, repetitive staticky roar that sounds like a [[Franchise/MassEffect Reaper]] [[https://www.youtube.com/watch?v=XVoU30ixHrM horn]] mixed with a helicopter rotor. Even creepier, if you listen closely to the repetitive waves of noise, it almost sounds like deep laughter.
** A [[MoodDissonance visibly terrified]] David singing "[[Film/TheMuppetMovie Rainbows are visions, but only illusions]]/[[SoundtrackDissonance Rainbows have nothing to hide...]]" You'll never think of Franchise/TheMuppets the same way again.
** The second season opens with a strange, rapid, frantic clicking noise that gets louder and louder until you realize what it is: the sound of [[spoiler:dozens if not hundreds of people infected with the Catalyst, [[AndIMustScream unable to move or do anything except for]] uncontrollably chattering their teeth together at inhumanly fast speeds]].
* ''Series/MyThreeSons'': When Katie finds herself alone in the Douglas house during a rainstorm, she hears something like a heartbeat, though she can't determine where it originates. Robbie dismisses it as maternal anxiety, and Katie initially agrees. When it happens again, Katie almost panics, until Steven Douglas points out that during heavy rain, the basement tends to flood. An automatic sump pump activates to remove the standing water, and its pumping mimics a heartbeat.
* ''Series/OrphanBlack'': The music that plays whenever Helena appears (or is about to appear) was this for the first season and a half. It still plays to herald her entrance, but her less villainous nature makes it less "hell" and more "something kickass".
* ''Series/RobotWars'' contestant Hypno-Disc, one of the deadliest machines on the show, was armed with a high-speed horizontal flywheel that, once it span up to speed, produced a horrendous metal shriek like a mechanical banshee (or "Satan having an orgasm", according to one Website/YouTube commentator). Considering [[https://www.youtube.com/watch?v=w04BgclPmY8 the kind of destruction it was capable of]], opponents had every right to be scared upon hearing that disc rev up to speed.
** The rebooted series had Carbide, a robot armed with a vicious spinning bar that emitted what the presenters referred to as a "death hum" as it spun at full speed. And rightly so, given that it once tore an armor panel off an opponent with such force that it went flying across the arena and embedded itself in a panel of ''bulletproof glass'' and left said opponent so badly damaged that the team had to resort to ''duct-taping its armor back on'' in order to get it battle-ready for its next fight.
* ''Series/{{Search}}'': The murderer's snarls and roars sound distorted and like a non-verbal VoiceOfTheLegion.
* ''Series/{{Sherlock}}'': In "[[Recap/SherlockS01E03TheGreatGame The Great Game]]", [[InsufferableGenius Sherlock]] makes a scraping racket on his violin to get his older brother, [[AloofOlderBrother Mycroft]], out of his flat. Some commenters on Website/YouTube have taken to calling this piece "Get the Hell Out of My Flat, Mycroft".
* ''Series/StarTrekTheNextGeneration'': One episode had dozens of whispers start up once an already disturbed cast member turned off the light to go to sleep. Hearing the voices would make her turn the lights on, and ''break her glass''. Just ordinary whispers, very loud and very numerous, when the good doctor is supposed to be completely alone. She gets even more disturbed by finding out who's making the whispers.
** On a very similar note, the clicking language of the extra-dimensional aliens in "[[Recap/StarTrekTheNextGenerationS6E5Schisms Schizms]]", one of the more terrifying episodes of ''The Next Generation''.
* ''Series/StarTrekVoyager'': In "[[Recap/StarTrekVoyagerS5E25S6E1Equinox Equinox]]", the (unrelated) extra-dimensional aliens have to open portals into our universe to attack. When a portal forms, the first thing they hear is a high-pitched, whining hiss. It's pretty creepy for the characters, who are asking, "WHERE IS IT? WHERE IS IT?". If they aren't fast enough, it's the last sound they'll hear.
* ''Series/StarTrekDiscovery'': In Season 2, the awful withered, wheezing [[VaderBreath strained breath]] of [[spoiler:his future self]] when Captain Pike sees a vision of the future. Even through the mechanical breathing machine, it's obviously the last desperate gasps of [[FateWorseThanDeath a mind in horrible agony]].
* ''Series/StrangersFromHell'': The thud-thud sound of Moon-jo bouncing a tennis ball against the floor is incredibly creepy and means someone's about to die.
* ''Series/TwinPeaks'' has the iconically bizarre backwards-reversed speech of the denizens of the [[EldritchLocation Black Lodge]]. Pretty much any time they appear to the characters, something ''very bad'' is about to happen.
** The bizarre, ghostly whisper-speech of the [[EyelessFace Eyeless Woman]] Naido in Episode 3, as well as her [[NothingIsScarier unseen mother]] pounding on the door.
** The [[HumanoidAbomination Woodsmen]] speak in [[BlackSpeech growly, raspy deep voices]] that sound like Tom Waits filtered through a broken radio.
** Carrie Page/[[spoiler:Laura Palmer]]'s utterly bloodcurdling scream. Made even worse because it's the [[spoiler:last thing that happens in ''[[GainaxEnding the entire series]]'']].
* ''Franchise/UltraSeries'':
** ''Series/ReturnOfUltraman'': Pris-Ma has [[http://ultra.wikia.com/wiki/File:Pris-ma.ogg a chilling cry]] that has to be heard to be believed.
** Zetton, the final monster from ''Series/{{Ultraman}}'', has a [[http://ultra.wikia.com/wiki/File:Zetton_Roar.ogg roar]] that can make one extremely uneasy, due to how foreboding it sounds.
* Much like what the ATF did in real life, they blast ear-splitting noises to the compound in ''Series/{{Waco}}''
* The 1972 TV-movie adaptation of ''[[Creator/MRJames A Warning To The Curious]]'' makes double use of this trope, heralding the approach of William Ager's ghost with either the sound of brush being chopped (in the woods) or that of tubercular Ager's gasping breaths (in Paxton's hotel room).
* ''Series/WheelOfFortune'': According to legend, when the slide-whistle sound effect was first added (whenever a contestant landed on Bankrupt) sometime in 1977, then-host Chuck Woolery acted startled and shouted out, "What was THAT?!" (To uproarious laughter, of course.)
* ''Series/TheXFiles'': The episode "[[Recap/TheXFilesS03E21Avatar Avatar]]" involves an old woman spirit-thing that visits AD Skinner in his dreams. When she appears, she makes a sound made up of garbled, distorted, agonized-sounding voices and a high-pitched shriek. He is terrified.
