Alright, we heard you the first time!
Anyone with a basic knowledge of physics knows how sound waves work
. Anyone who's been up close to the stage of a rock concert can tell how well they work when it gets loud.
This, though, is that feeling taken beyond what's possible in real life. A sound or series of sounds, if sufficiently loud, will push someone or something around as would the wind of a hurricane or tornado, well beyond what would happen in Real Life. This trope is almost always played for laughs, but the Rule of Cool has it weaponized now and then as a type of non-standard elemental damage combining aspects of Blow You Away, Glass-Shattering Sound, and Explosion Propulsion.
Note, however, that this doesn't cover sounds that are genuinely that loud, like a rocket launch, nor does it cover giant monsters like Godzilla or King Kong roaring in someone's face, where their breath would come into play.
In Real Life, sounds loud enough to move objects are above decibel level 194. At this level, they are no longer sound waves moving through the air so much as they are shock waves pushing the air along in front of them. You don't want to be anywhere near a place where this trope is happening in real life. It's not a gale, it's a battering ram.
Contrast this trope to Brown Note and Loud of War, where the sound has a purely psychological effect on the target, as opposed to the physical effect of gale-force sound. See also Glass-Shattering Sound, where the effect is limited to glass. Super-Scream has a similar effect, but only caused by a person's voice, and it's less frequently used for comedy, and Musical Assassin, who may use their music for this effect (but just as likely play Brown Note music).

Advertising
- A 2001 ad for Computer Associates has a bunch of roosters gathering in New York City to crow all at once, creating a sound shockwave that blows away everything in its path.
- The famous "Blown Away Guy" Maxell tape commercial from 1980. Also done in print form (and in the UK, the guy listening to the music is Peter Murphy!).
- Some Brazilian ads from The '80s for a Philco stereo has this happening to (CGI) ants. The second ad has them wearing F-1 helmets.
- One of a series of idents for UK Channel 4.
Anime & Manga
- Bleach: Upon first activating his Resurrección, Grimmjow lets out a deafening roar that briefly pushes back Ichigo, who is shocked that Grimmjow's roar alone is this powerful.
- All-Purpose Cultural Cat Girl Nuku Nuku: In the episode "Nuku Nuku Is Touched! Futaba's First Love!," during her possessed state of demanding Mishima products on her classmates, she gets so frustrated that she decides to blow very hard on her whistle, causing the whole classroom to be blown around.
- My Hero Academia has Present Mic, whose Quirk is being able to amplify the sound of his voice into a Super-Scream so oppressively loud it can knock down people and send bits of debris flying. Worse yet, it doesn't decrease with range; Mic has been shown blowing out eardrums just as effectively from hundreds of meters away as at point blank range, meaning the windstorm he can generate is equally powerful for the entire distance his scream can be heard.
Asian Animation
- In Season 7 episode 20 of Happy Friends, Ambassador Wang screams at Big M. and Little M. loudly enough to blow them to a nearby tree.

- A Chance Meeting of Two Moons: Artemis's Royal Canterlot Voice is sufficient to knock Solaris backward during an argument.
- Escape from the Moon: In the sequel The Mare From the Moon, Twilight manages to send Spliced Genome flying by the sheer force of the Royal Canterlot Voice when she gets angry at Spliced saying she'd abused Spike by the way she raised him not to horde.
- Fairy Friends: At the end of "Sun and Fun," Veronica squeals so high and so loud that it creates a gust of wind strong enough to blow around Tootie and Trixie's hair. The reason for the squeal is Jermaine telling Chloe and Veronica that Tootie and Trixie are now his girlfriends.
- Kaleidoscopic Katamari: Foomin possesses both wind and sound-based magic, implying that she could be capable of acheiving this effect by combining the two. However, her powers haven't quite developed this far yet.
Films — Animation

- Zigzagged with the Scream-Scream Devil Fruit in One Piece: The Movie; lore-wise, it lets the user, Big Bad El Drago, scream so loudly that it hits like a turbo-charged battering ram, punching through whatever is in the screamer's way. However, it's visually depicted as just a generic energy blast that happens to be launched from the user's mouth.
- Over the Hedge: During a heist, one of the porcupine kids accidentally turns on a TV, which plays the infamous THX Deep Note. He slides backward as if he were in a wind tunnel, and a few quills are blown off his head, narrowly missing RJ and Verne.
- In The Rescuers Down Under, Wilbur is playing loud music and can't hear Bernard and Miss Bianca calling him. As Bernard walks over to Wilbur's boom box to turn it off, he is clearly being blown back by the sound.

Films — Live-Action
- Near the beginning of the first Back to the Future 1, Marty plugs his electric guitar to a ludicrously huge amplifier in Doc's lab. He plays a single chord and is physically hurled backwards by the sound, which destroys the speaker in the process. As Vsauce demonstrated in a video about the movie, the shockwave would also have destroyed Marty's eardrums and, in all likelihood, his skull.
- Bedknobs and Broomsticks: STOP! THAT! BAAAAAAAALLLL!!!"
- In Cheech and Chong's Next Movie, Cheech has a devil of a time getting inside his own home when Chong's playing a solo. Chong's playing also blows playing cards away, causes dogs to cover their ears, and makes neighbors take cover.

- Kung Fu Hustle features the Harpists, two villains who fight their opponents by playing a guqin (Chinese zither) that makes sounds loud enough to knock people down. This is easily topped by the Landlady's "Lion's Roar" technique, which shakes buildings and cracks stone columns. When this fails to affect the Beast, the Big Bad of the story, her husband helps her rip the top off a funeral bell and holds it up for her to use as a megaphone. The result is a sonic tornado that reduces the room to splinters, with the Beast becoming a rapidfire participant in Oh, Crap! and Blown Across the Room. This does hurt the Beast, and when she moves in to give him a second dose, he promptly surrenders. NOT.
- Lost in a Harem: While Peter and Harvey are sleeping in a tent with a bunch of Prince Ramo's followers, one of them snores loudly enough that he keeps blowing another man's beard in Harvey's face. Even tying a bag of weights to the beard can't stop it from being blown over.
- Stay Tuned: The Maxell "Blow Away Guy" is parodied in a "Max Hell" cassette tape commercial, in which the same "Ride of the Valkyries" music blows the listener's head clean off.
- Near the end of Teenage Mutant Ninja Turtles II: The Secret of the Ooze, Mike and Don blow Shredder out a window by turning the speaker he's standing in front of at maximum and hitting a power chord.
Literature

Given this opportunity, they decide to do some things they normally wouldn't be allowed to do, like crank the stereo up to full blast. The impact blows them both across the room and into the wall.
- Black Books: Manny bets Bernard that he can sell a book to the next person to enter the shop; he tries it, but doesn't even get as far as "hello" before the customer unleashes a furious rant about not wanting to be pestered by salespeople in shops, the force of which blows Manny's hair back.
- The Red Green Show: In one "Handyman Corner" sketch, Red gets annoyed by a neighborhood punk driving around blasting grunge music out the windows, and sets out to retaliate. He does so by building a gigantic speaker for his own radio that fills the entire side door of a van, powered by every amplifier he could find all wired in series. The resulting rendition of the Washington Post March is so loud that it actually overturns the punk's car, as well as shaking apart a nearby shed.
Music
- In the video of the Lindsey Stirling song "Roundtable Rival", the guitarist's amplifiers are able to blow down Linsdey and her backup dancers. Lindsey uses the same amplifiers to even greater effect against the guitarist when she plugs in her Stroh violin.
- Manowar have slipped the occasional line about getting this loud into their song lyrics, perhaps most prominently in "The Gods Made Heavy Metal".
- The video to the Nickelback song "Gotta Be Somebody" demonstrates the trope nicely, with cracks in the ground and general earthquakes accompanying the refrain each time.
Tabletop Games
- Dungeons & Dragons 4th and 5th Edition have Thunder damage, which was known as Sonic damage in 3rd edition (the change was to make it sound more fantasy and less science fiction). Many spells and effects that cause Thunder damage also have the effect of knocking the target away from the caster, like the first level wizard, sorcerer, and Tempest cleric spell Thunderwave. In the 5E supplement Fizban's Treasury of Dragons, the Metallic Dragonborn subrace has breath weapon option that can shove people away.
Video Games
- ANNO: Mutationem: After Hulking Out, one of the Bloodluster's attacks is performing a super roar that not only causes Ann to be blown across the area but also inflicting a confusion aliment.
- Brütal Legend has the Earthshaker move, which causes Eddie to do a power chord on his guitar that damages nearby enemies and sends them flying.
- The Elder Scrolls V: Skyrim: The infamous Unrelenting Force, one of the first Dragon Shouts you learn, is capable of blowing people in front of you backwards into the air at full power. Indeed, one of the easiest ways to kill most enemies (up to and including some bosses) is to just punt them off the nearest cliff.

- Invoked in NEO: The World Ends with You: Sound is one of the elements that psychs can possess, and Gale Force is the name of a psych, of which the stronger ones available before the credits roll are in fact Sound-elemental.
- The Killer Wail from the original Splatoon exhibits this effect, but only against entities who have deployed a Bubbler or transformed into a Kraken, due to the invincibility effect provided by those. It is impossible to tell if this effect works on normal Inklings, typically because they do not last long enough.
- Viscera Cleanup Detail: Among the game's normal in game radio "the big banger" which appears on every level, The game also has one unique "The Bigbanger: Supernova Edition" in game radio. While the bigbanger sound players are described by in game documents as a model that has won a contest by having "Earth-shattering" loudness, the normal Bigbanger radios players encounter simply produce sufficient sound to broadcast music throughout the level and shakes itself while doing so. The "Supernova" edition of the player, however, can produce music that is obviously louder than any in game sound effect, at the same time shaking every object in the area, sends all the small objects in the vicinity flying, setting all the flares alight, detonating any dynamite within medium range, and shakes the bucket machines and bin machines in to producing buckets and bins.

- From Transformers: Animated, there's the rock battle between Optimus Prime and Soundwave, in "Human Error, Part 2".
- In the Wakfu episode "The Black Raven", Miranda yelling for her husband Kabrok blows back Amalia's hair.
Real Life
- There exists a smartphone app that emits a sound with a frequency low enough to exploit the fact that "exhaled" air is pushed in a more focused direction than "inhaled" air, and has been used to blow out a candle. However, it puts stress on the device's speaker, so one's own exhalation is more practical.
- As was demonstrated on MythBusters, supersonic aircraft can rattle windows and, in certain circumstances, shatter the glass. There's also the risk of eardrum damage.
- This is referenced in an episode of Garfield and Friends: Jon reads about the sonic boom, calls Garfield for lunch... and the cat arrives at the speed needed for it to occur and start destroying the kitchen.
- The Republic XF-84H Thunderscreech turboprop experimental plane had a propeller whose blades turned at supersonic speed. The result was a continuous sonic boom that could damage other aircraft, caused nausea and hearing damage in several personnel, moved volumes of air with enough force to knock people down, and was directly responsible for inducing a seizure in one unfortunate ground crewman.
- The Other Wiki talks about Operation Bongo II over Oklahoma City which led to the US halting SST development.
- An explosive-driven sonic "Wunderwaffe" that could knock down planes was in development in Nazi Germany. It actually worked, producing waves of sound which were highly destructive — within a range of about a dozen yards. Zurück zum Zeichenbrett!translation
- Pistol shrimp use their claws to form a cavitation bubble that then implodes and stuns or kills their prey with a shockwave.
- Dynamite fishing — illegal in most places — uses this trope. The shockwaves from a dynamite explosion can be much stronger under water, and will stun all fish in the vicinity.
- The MythBusters also found out that this is why shooting fish in a barrel is so easy. Even if you miss with the bullet itself, the shockwave it creates in the water will kill the fish anyway.
- If a pursuing predator catches up to a chicken, the chicken can escape by slapping its wings against its own body. The resulting thunderclap will only disorient its pursuer for a second or two, but that can buy it enough time to get away.
- The Chrysler horn (not to be confused with the horn on board Chrysler cars) is a nuclear air raid siren run off of a souped up v8 engine that's designed to warn an entire city from well outside city limits. When cranked up to max volume, these sirens have started fires, broken glass, killed animals, and cause material fatigue to nearby buildings and equipment. The fact that it could start fires with its sound couldn't even be confirmed for almost fifty years, because the sound alone broke the instrumentation needed to confirm this hypothesis (many tried to explain the random grass fires as the siren spewing gasoline due to internal mechanical failures). It can do these things because it has such a large wave amplitude that when the sound collides with an object, it causes a massive vibrations similar to an object at its resonance frequency (only with the Chrysler horn no resonance frequency is needed). These vibrations are then displaced as heat and cause material fatigue, causing stuff to break over time.
- Long Range Acoustic Device weapon can send painful sound waves.
- 200 decibels can rupture your lungs. Luckily, you literally need a nuke, or copious amounts of Stuff Blowing Up at least, to get that kind of noise. The decibel scale is logarithmic; put simply, to register 10 more decibels requires ten times the power. To compare, a rifle shot generates about 150dB at point blank. A 200dB sound requires 100,000 times more power, and because of the rapid drop-off only applies at the source. In general, that kind of pressure wave (which is the "loudness" part of the sound) is less a sound, and more of an explosion, and even then anything higher than 190 is hard to achieve because our particular atmosphere doesn't really assist much.
- The 1883 eruption of Krakatoa produced a sound so loud that it crossed the Earth over seven times, could be heard from over 3000 miles away, and retained a volume of at least 180 decibels 100 miles away from the source. Given the sheer force of the eruption, Krakatoa is almost certainly the loudest sound ever produced in modern history.
- The 1883 eruption of Krakatoa
- Some children's entertainers invoke this trope after asking the kids to yell as loud as they can: during the scream, the entertainers throw themselves against a wall as if being against a very strong wind.
