In real life, even in the best of circumstances we often have to repeat ourselves to be understood by the people we're talking to.
In fiction, when conversations are taking place, they will sometimes benefit from a strange, localized phenomenon of crystal clear acoustics. It doesn't matter if they consist of several paragraphs of Sesquipedalian Loquaciousness, the words will be heard without any trouble by both target and audience, even in the midst of a crowded nightclub dance floor being buzzed by a 747. A particularly handy feature for The Quiet One, but also for action heroes making sure the villain hears their cool Pre-Mortem One-Liner despite them both dangling from a speeding helicopter.
This is an Acceptable Break from Reality, as the audience needs to be able to hear what the characters are saying in order to understand the plot, and it would be tedious for a character to repeat what they said because they weren't heard the first time.
Related to Easily Overheard Conversation, Seven Minute Lull, Stage Whisper and (distantly) Realistic Diction Is Unrealistic, as well as Talking Is a Free Action for a different sort of an unusually nonproblematic conversation. For the effect that loud sound doesn't have on the ears in Hollywood, see Steel Ear Drums.
Part of the Artistic License tropes.
- Bubblegum Crisis - The Tokyo: 2040 series has a great example in the episode "Minute by Minute". Priss and Leon have a quiet conversation together... while speeding down a highway on motorcycles. No evidence of radios here, and in fact it's even crazier because Leon is wearing an open face helmet while Priss's helmet is totally enclosed, which would muffle her voice even if they were at a dead stop.
- Zigzagged in Porco Rosso. Sometimes, people communicate plane-to-plane via morse code, as they did in real life. Other times, they simply shout, which in real life would have been impossible.
- In Nausicaä of the Valley of the Wind, people have no problem talking to another in-flight from gunship to gunship without their voices being drowned out by wind and the noise from the engines.
- In K-On!, the girls attend an open air rock concert and have no trouble talking to each other at a fairly normal volume.
- Attack on Titan: Characters will often have long, complicated conversations while galloping on their horses. In real life, riding a galloping horse takes a bit of concentration, and you’d need to seriously be shouting at people riding next to you to be heard.
- In the Warhammer 40,000 comic book Blood and Thunder, the newly-proclaimed Ork Warboss Skyva gives a speech from the top of a Gargant (a war machine standing over a hundred meters tall) to the thousands of orks at its base. Justified in two ways: not only are Orks really really good at shouting, they can make physics bend to their will slightly based on what they think should be happening.
- In Death of the Family the Joker has crudely reattached his face and can still talk, but he shouldn't be able to control his lip movements and speak without mispronouncing certain words. (Think Nicolas Cage in Face/Off.)
- The League of Extraordinary Gentlemen actually shows the confrontation between Sherlock Holmes and Moriarty at Reichenbach Falls, something the original story by Arthur Conan Doyle that it's taken from, "The Final Problem", never bothered with (Watson just finds a letter and signs of a struggle and assumes what happened). Doyle thus sidestepped any problems of two men engaging in dialogue right next to a plunging, roaring waterfall, while Moore forges right through with sesquipedalian flair, as seen here.
- The Night of the Owls arc in DC's New 52 culminated in Batman #11, an excerpt of which serves as the trope image for this page. That panel isn't a fluke: all throughout a fight involving screaming jet engines, explosions, and men getting punched through brick walls, Lincoln March keeps up a steady stream of convoluted conversation regarding his backstory.
- Averted in the Freefall Romance scene from Chapter 39 of Kyon: Big Damn Hero. As it happens to skydivers and parachutists, it's normally impossible to speak to another person in such conditions. Yuki bypassed this by touching his skinsuit and transmitting her voice through bone conduction.
- My Immortal: Enoby and Vampire manage to have a perfectly nice chat at a rock concert, in the mosh pit. Then they hear Draco crying, again, over the sounds of the mosh pit, and go to ask him what's wrong.
- Hilariously subverted in Kung Fu Panda 2. After Lord Shen has shot Po with a cannon, he sails his ships to open sea in order to conquer all of China. Then he sees Po atop a roof far away. Po stands heroically and then starts giving an inspiring speech... except no one can hear him. After a few confused "What?"'s, Shen gives up trying to understand Po and just orders his troops to fire.
- In Bee Movie, there are numerous cases when you have to wonder how is it possible that everyone can hear a tiny bee crystal clear, no matter the distance. It gets especially stupid during Barry's speeches in the court during a trial, where he doesn't use a microphone or anything like that, and yet everyone can perfectly hear him.
- This is incredibly common in movies and shows featuring characters who meet up at a dance club or strip joint. It's usually impossible to have any conversation below a shout because the bass is turned up to an organ-thumping level in these establishments, but in films and TV, characters can converse at any volume, down to a conspiratorial sotto voce, without a single "WHAT?!" between them.
- Freejack has a scene where the hero is overheard talking by a camera crew from across the floor of a nightclub pounding with music.
- For practical purposes when filming the movie, there were a few scenes in Saturday Night Fever where the main characters had to be dubbed over by voice actors because the discotheques were too loud for the actors themselves to hear what the other was saying, let alone the recording equipment and the audience watching the film.
- Monty Python's Life of Brian has a famous aversion during the Sermon on the Mount.
Audience member: ... did he say "Blessed are the cheesemakers"?
- Airplane! has a scene where a couple continue to have a conversation as one is standing in the doorway of a plane in the midst of takeoff and the other is running along on the ground beside it, in parody of the Train-Station Goodbye.
- In the movie Aliens, Bishop ends up in a very windy environment as he's calling down the reserve dropship. Even so, you'd think hollering into his headset to communicate with the people on the other end would be counterproductive, but they don't even flinch, and understand him just fine.
- In Back to the Future Part 2, Marty is hiding in the back of Biff's car while Biff is driving. Marty is talking to the Doc on a walkie-talkie. At first, it seems to be an example of this trope when you wonder how could Biff not hear him, he is talking so loudly. However, it turns out to be Fridge Brilliance and an aversion - we are hearing from Marty's point of view, but the car is an open top convertible and Biff would have the wind in his ears.
- In Crank, Chev Chelios calls his girlfriend and leaves a goodbye message on her answering machine as he is falling from a helicopter several miles above the city. There is practically no wind noise as he does this. This turns into a Parodied Trope in the sequel where it's shown that his girlfriend heard none of his heartfelt speech because the only thing recorded on the machine was the overpowering sound of rushing wind.
- Mad Max: Fury Road mostly takes places at high speed with a fleet of massive, mostly unmuffled V8s and the Doof Wagon around yet wind noise only shows up maybe once and the roar of the engines is only audible when the vehicles themselves are the focus. People have no trouble yelling to other vehicles across several meters of air that should by all rights be flooded with cacophony.
- Full Metal Jacket The scene in the helicopter where the gunner is getting interviewed while firing his gun. Aircraft have headsets and microphones, but there aren't many examples where they USE them as intended, instead they act as though they're protective in nature (IE gun range earmuffs) rather than communication devices - instead electing to raise their voice or shout over the DIN.
- Halloween: Resurrection: Sara is in a college classroom in the beginning. When the professor asks a question, and she answers, her voice is barely higher than a whisper, yet the professor hears her clearly and responds.
- In Jerry Maguire, Dorothy is able to eavesdrop on a quiet conversation Jerry is having on an airplane while the engines are running, despite sitting in a completely different section.
- Played straight in Lethal Weapon, where Riggs and Murtaugh carry on a conversation at a firing range, complete with earmuffs.
- The first Mission: Impossible movie features a climax where hero and villain are indeed hanging off a speeding helicopter. Following just behind a TGV Bullet Train travelling hundreds of kilometers per hour. In a tunnel. Given this, it's probably just as well Ethan Hunt uses visual aids while shouting "Red Light! Green Light!", so that Phelps can properly recognize things are about to get a little 'splody.
- Averted in The Naked Gun, where a hitman tries to deliver a "message" to Drebin from the Big Bad by cursing and opening fire on him. Drebin's response:
"Sorry, I can't hear you! Don't fire the gun while you're talking!"
- Revenge of the Red Baron has a doozy of an example of this trope. Two WWI pilots in open cockpit planes, dogfighting each other, are able to trade threats and insults through the communicative power of shouting their lines.
- Snake Eyes features Nicolas Cage's character Rick Santoro somehow not only hearing his cellphone ring while sitting in the front row of a crowded sports arena during a boxing match, but having a conversation on it with no problem.
- Averted in The Thing (2011). During the helicopter ride at the beginning, Carter, one of the pilots, waves at passenger Kate to put on the headset next to her so that they can talk clearly.
- At the end of the film version of 300, the narrator is talking to an army of over ten thousand men. Somehow, the guys way in the back, who are probably half a mile away, hear him perfectly fine.
- The Two Towers. When Saruman is addressing his army of ten thousand Uruk-hai, his voice appears to be magnified by magical means. However in the extended version of Return of the King Saruman speaks to the protagonists from the top of Orthanc and no similar effect is used (online cartoon spoof site Sev Trek suggested that he was using his pointy wizard's hat as a megaphone). Justified as Suruman is literally a wizard and amplifying your voice at will is shown to be a wizard ability and is used at other points in the films.
- This Is the End: Even a roaring party is not loud enough to prevent gentle knocking being heard at the front door.
- In Point Break (1991), Bohdi and Johnny Utah have a conversation in freefall.
- The climax of Horton Hears a Who! has the entire worldwide (speckwide?) population of Whos making as much noise as they can in a last ditch attempt to be heard by animals other than Horton. It doesn't work, until the addition of the shout of one small child makes all the difference.
- Redshirts: During a battle, Chief Engineer West replies to comments by Abernathy and Q'eeng just after entering the bridge, meaning he was somehow able to hear them through a door, with red alert sirens blaring.
- Averted in at least one other Star Trek novel, during which Worf and Data are riding on top of high-speed vehicles. Worf is able to hear Data, who is sitting in front of him, but Worf is unable to reply because of the sound traveling backwards at such high speeds.
- The first Twilight book features Edward and Bella holding a conversation while he runs at superhuman speed and she clings to his back. In some cases, the dialogue even states that they are whispering, despite the fact that the wind whipping past their heads should make even yelling next to inaudible, at least for an ordinary human like Bella.
- In The Tenets of Futilism, Sasha and Joe seem perfectly able to have conversations in noisy, crowded areas without speaking loudly or whispering into each other's ears.
- Lampshaded in H.P. Lovecraft's The Dream-Quest of Unknown Kadath, where it is mentioned that the Dreamlands have their own rules about sound and air.
- Averted in an episode of Law & Order: Special Victims Unit. Casey turns around and speaks in low tones during a trial to prove that a witness could not have overheard a dialogue carried on some distance away in a crowded room. Indeed, no one could hear what Casey had said in the courtroom.
- House MD - The episode with the rocker with epilepsy triggered by chaotic music. House brings in a marshal stack and plays REALLY LOUD MUSIC... and then asks "so what were your inspirations for this" over the cacophony.
- How I Met Your Mother - Averted in the fifth episode of the first season. The gang goes out to a nightclub, and while on the dance floor no one can hear each other, except when there're momentary lulls in the music.
- Both played straight and averted in Perry Mason, depending on the episode. Some witnesses would whisper or sob during their big moments and be heard perfectly; other times the judge would instruct them to speak up.
- The Mythbusters examined the plausibility of the Point Break (1991) example above by having another skydiver tell Grant a "pull my finger" joke in freefall. The joke was completely inaudible.
- Subverted in the final episode of M*A*S*H, "Goodbye, Farewell, and Amen". As BJ Hunnicutt is departing, Klinger tells Col. Potter that Hunnicutt's discharge orders were rescinded, but Potter pretends to be unable to hear the message because the helicopter taking him away is too loud.
- Also averted when orders have to be relayed down a long vehicle convoy when the 4077 is moving camp. This is then Played for Laughs when Father Mulcahy decides to bless the new site, with the words of his prayer shouted from one truck to the next.
- Accidentally averted in Freeman's Mind. Due to technical issues, the scientist at the end of the Lambda Core segment (i.e. just before Xen) was virtually inaudible above the noise of the gate opening and the aliens attacking. Ross Scott decided to leave it in rather than re-recording the segment because it was funnier that way.
- Battlefield 3 averts this trope in some scenes, notably in Going Hunting where the first Iranian fighters are encountered. You don't hear their planes' cannons until well after the bullets start hitting and/or passing by you. At the same time, though, the introductory sequence for the mission has the player character and her partner not bothering to put on their helmets, thus getting any sort of ear protection, until well after they've arrived on the flight deck, just feet away from their own already-running F/A-18 and a few more away from their wingmate launching from the catapult.
- In the iOS game Highborn, the characters are often able to talk from across the map. This even gets Lampshaded once:
Trillian: Wait, how are we even talking?
Enzo: It's a plot device; roll with it.
- In Dynasty Warriors, Samurai Warriors, and Warriors Orochi, you are always cognizant of what's going on over the entire battlefield even though you're controlling a single warrior (or single team of warriors traveling together, in the case of Orochi)—you can instantly hear allies calling for help, ambushes go off, reinforcements show up, etc., and get a corresponding Notice This ping on the mini-map.
- In Grand Theft Auto IV: The Lost and Damned, you frequently participate in conversations with your fellow gang members while cruising down major roads and even highways on motorcycles. They're not even yelling at the top of their lungs. In real life, the noise of the motorcycles plus the wind would make this sort of conversation impossible.
- Red Dead Redemption: It's quite easy to have a conversation with someone while you are both on different horses thundering down a hard dirt road.
- Averted in this Oglaf comic (SFW, other pages not). Then played straight in the Alt Text regarding the tidbit of Fridge Logic.
- Averted in El Goonish Shive. In the middle of an aerial chase, the bad guy starts boasting and making threats.
Nanase: (speaking telepathically) Can you understand what he's saying?
Ellen: (likewise) All I can hear right now is "Whoosh."
Nanase: Me too.
- Plot-relevant, as Ellen and Nanase miss a reveal this way.
- Averted in this ''Paranatural comic. It's hard to understand someone when they're speaking with their back to you.
- Adventure Time Zig-Zagged in the episode "Belly of the Beast". Finn and Jake are first ignored and then misunderstood as they try to talk to some bears in the middle of a noisy rave party, but then in the same space they have a quiet conversation with another bear with no problems.
- SWAT Kats: Sometimes aircraft-to-aircraft conversations take place via radio or video comm channels, but oftentimes people would just say things, and the SWAT Kats would be able to somehow hear them inside their active supersonic jet. Really, the noise from the Turbokat was just severely played down or outright eliminated in a lot of circumstances, otherwise talking and sound effects would just be blared out by engine noise.
