For a film getting it right, what about Master and commander, 1st scene with the eerie silent flash of lights in the fog before the woosh of cannon balls.
You are completely correct, but they do it BECAUSE MOVIE. :) However, one could argue that the position of the observer is not fixed to the point of view of the camer but rather that the observer is "omnipresent" and follows both the sniper and the target simultaneously. Otherwise, if you for example show a sniper shooting and then cut to the target, you should technically hear the "bang" twice, which would be just confusing for the audience.
But sound in movies is nearly always tied to the current shot in question, from the perspective of the characters we see in it. We hear, to a very large extent, what the characters actually would hear. I would say the reason for unrealistic sound effects is just corner-cutting by the filmmakers, or even ignorance.
@@thejcquartet6943 It would not be difficult to delay a sound and the artists that create the movies and effects are on the whole pretty passionate. It is more often then not a contentious discussion to make things unrealistic so that the audience things it is realistic. Not because they think the audience is stupid but simply because anytime the audience is pulled out for even a moment, you've done your job bad. Humans don't think scientifically, most people know that sound isn't instant but when they hear it happen it can be jarring or confusing. You can intentionally use the speed of sound to disorient the audience if that is the sort of effect from the scene but you can't do that all the time. When you make movies you need to account for the flaws in your species very bodies. It isn't about intellect or corner cutting. Other times it is just habit. You are a sound designer for so many years you see the fireball, you put the bang on top. You wouldn't do it any other way normally so people just stop thinking about it.
+violacrb True. It reminded me of way back when I was a kid and my grandpa complained that tv and movies no longer made it easy to pick out the good guys and bad guys just by what they were wearing (i.e. white hat/black hat, etc.) and I think I looked at him like he was crazy at the time, but really I was just dumbfounded at the idea that this might be a necessary cue instead of just a joke.
HeathLedgersChemist That's so... So fucking terrible! I *LOVE* it! My god, you've hit a new level of cheese. You know what happens if you keep heading south?

Classic. Used to guess the distance of thunderstorms as a kid. See the flash, count the seconds until you hear the thunder, divide it by 3 (343m/s, 1/3 of a km) and you got the distance in kilometers. Now in imperial: 375 yards per second, 1 mile is 1760 yards (eh, yeah), so that's a mile at 4,7 seconds. So devide your counting by 4,7. It's just that the relations between the units are completly random, what makes it over-complicated. Not very convenient, isn't it?
Knowing this was *very* useful growing up in an old house since you would have to unplug all electronic devices to not risk them burning out if the lightning were to hit a power line too close to you.
Dragon7722 That's the problem, lightning can strike miles away. Don't believe me? Here's the NOAA advisory: www.crh.noaa.gov/Image/gid/WCM/safety/lightning.pdf Relevant information: Lightning can strike as far as 10 to 15 miles from the area where it is raining. That's about the distance you can hear thunder. If you can hear thunder, you are within striking distance. Seek safe shelter immediately.
+Zoey Chevalier ARMA also simulates the bullets. So normal bullets come with a crack while subsonic ammunition doesn´t have that. But they are slower and therefore have greater bulletdrop hence less range
i'd get crazy trying to figure out how long 150*3/8 inches are in yards. as a metric user it almost feels like no one ever converts or multiplies any numbers in britain or the us
+Penispumpenshop24.at I would say though that in everyday usage, Metric is a bit better, due to simplicity. Like a 1000 miligrams = 1 gram. Whereas with the Imperial system, it is kind of inefficient even for everyday use.

Saving Private Ryan even calls this out with their sniper scene; that one guy was shot and on the ground before you heard the bang (as even stated by their own sniper).
saving private ryan to my knowledge is the only movie that gets it wrong, but in the wrong direction Based on how far that sniper was away it should have taken 1.2 seconds for us to hear the gunshot, we heard it after 3 seconds
Last episode of better call saul featured a gunshot with accurate sound delay. I just got home and I've spent my drunk evening thinking about that. Then I enter youtube and you've made a video about it!
+Marcelo Henrique I replayed the scene in Breaking Bad where a sniper's shooting at Gus's men. First you hear the impact with the woosh, then the sonic boom and the bang is the last in order. Incredible how they paid attention to such small details.
Whenever I see real footage of explosions, the sound delay gives me chills! It's so much more suspenseful and it gives you a sense of how big the explosion really was. I think it would be quite a revolution in film making if they capitalized on that effect.
Oh! This is most useful information at the tail end there! Speed of sound in chloroform is 987 m/s! I'll remember that on my next date. I hope it will knock the girl off her feet in an instant!
I've got a good one: medieval warrior physiques. They're obviously portrayed by bodybuilders in movies these days, but back then they didn't have modern gym equipment, nutrition, growth hormone, etc. I've always wondered this, and I hope you could do a video on it! Thanks!
Yeah, this effect is perfectly replicated in game ARMA 3, you can hear the sound crack, the sound travels at reaslistic speeds, really gives you idea how does it sound. Interesting list of sound speed thru various materials Lindybeige, but to me the far most interesting is water :)
+Mikee CZ Another game that does it correctly is the Combat Mission series, from CM:Shock Force onwards. A pretty legit wargame, btw. Strangely, in those games I found it a lot harder to accept what I was seeing/hearing, as it is a 3D wargame where you can move your camera freely so unlike Arma3 no avatar to channel your expectations of what you should be hearing when. So games had me trained to accept sound to be instantaneously and to find realistically modelled sound to be strange. Thunder storms and firework shows were apparently insufficiently common to train my expectation level in games.
4:08 I don't know about you guys but I find the silent flashes and the big growling that comes afterwards way more intimidating. Just step outside or open a window in a thunderstorm in summer and you just know what I mean! It is so RAD!.
+Дмитрий Иванов In which case he could have brought in an appropriate pianist. Ha ha! In some of our lecture halls at the University there are ooooold pianos suitable to the task.. but so far no one has ever played them (except me.)
To put into perspective how fast light is compared to sound: if there was sea-level air all the way to the moon, and someone set off an extremely loud explosion there (maybe using a parabolic dish to get more of the sound heading towards you), it would take about a second before you saw the flash, but you'd only hear the sound (assuming it was still audible) a week and a half later...
Light speed is ~300 000 km/s (in vacuum), the speed of sound (in dry air) is ~0.345km/s, so yes it would take a huge amount of time before you heard the sound of a massive explosion on Earth in the Moon, if sound was capable to travel in a vacuum, that it not and thanks goodness that it can't, because if it could travel in vacuum the noise from the Sun would kill us. Btw even tho light speed is so fast, it takes ~2.7 seconds for light (or radio signals) to reach the Moon from Earth and vice versa, so you would only see the explosion flash in the Moon 2.7 seconds after it happened not one second.
this is something I do in my editing when making my cartoons (if I have a long enough running shot) I'll delay far sounds. It really adds to the atmosphere :D. great video btw :D
When I was a young lad there was a sniper movie, "Day of the Jackal". In one scene, the sniper is taking shots at the intended target. In the scope you see the target moving about normally while he is being shot at. I, not understanding physics yet, was screaming at the TV all the while little plumes of smoke (indicating near misses on the ground) are seen. My dad had to come in and explain that the target was not being brave or stupid but rather was completely unaware of the danger. Many years later I was exposed to the remake. It was interesting how the two movies utilized sound The first movie used silence very effectively. The second was a Hollywood blockbuster.
+Ben Barker Even if the rifle is far away and uses a suppressor, you would still hear a very loud bang as the bullet fly next to your head. The sound the bullet makes is very similar to a whip crack (because the tip of the whip is also supersonic), so it is very loud and you cannot be unaware of it
IIRC you can hear a bullet exactly at the time it whizzes past your ear. That is a different sound wave than the sound of the bullet leaving the barrel. My dad, an artillery commander always told me if you hear the boom you know they didn't hit you. It's when you hear one whistling that you know they were close.
Being raised by a gunsmith and competitive shooter has ruined many movies for me. By the way, if you ever watch "Quigly Down Under" they actually take the speed of sound into account. A round lands and they wait for the report, then use that estimation to determine how far away roughly the rifleman is.
+David Stewart yes, probably one of the very few movies that take this into account..I was like 12yo when I saw it first time, and when the bad guy riding a horse gets hit and you hear the bang later, well... I was so excited that finally someone got it right that I talked about it for a couple of weeks
It's what immediately came to mind for me, too. I don't know how much else of the marksmanship stuff in the movie is accurate, but that was certainly gratifying. And, frankly, exciting. That's something I don't get. Seeing a huge explosion at a distance, then actually hearing it several seconds later would make it seem even more impressive, to me. It depends on the situation, to be sure, but it can go a long way to setting a specific tone. A movie example of this is is the original Red Dawn, when there's an explosion in the background during a scene which you see, but to which no-one reacts until the sound reaches them. It added a surreal, menacing feel, seeing it, and not hearing it immediately..
One movie that got it right was "Quigley Down Under". In fact the bad guys used the sound delay to figure out the distance to the good guy sniping at them.
+bobobobinalong I think because of the ammunition and the range. The bullet had become subsonic by the time it had reached it's target. So there was no sonic crack.
One of my favourite films is Master and Commander, and there's a great scene where the French fire upon the Surprise and they do account for the sound not reaching the ship until much later. Perhaps you know the scene I'm talking about. Anyway it really improves the whole scene a great deal. This is one of my own pet peeves too. Good work Lindybeige, as always.
Wait, you took a ronded estimate of the speed of sound in feet, and then took a dig a the metric system when the resulting number converted to meters wasnt very clean? Kinda dishonest. How about you took the rounded metric number, 340/s, which would give you 13,6 meters per frame, converted to feet it would be 44,6194226 feet feet per frame.
+MaMastoast Precise conversion in either direction is messy. If you want easily handled measurements, don't convert, just stick with whatever system you actually used for the initial measurement (and, yes, LB has a prejudice here).
I really like that you provided video footage with the slight delay in audio. Even if they don't utilize the sonic boom you mentioned earlier I think that the delay between seeing the effect and hearing the sound actually enhances the film watching experience, it's a lot scarier especially when the camera is positioned from the point of view of the target.
I remember there was a scene in True Grit (the 2010 version with Jeff Bridges) where one of them fires his rifle into a valley in which you hear the initial shot and then the echo a few seconds after it hit its target. It was kind of that scene that made me realize how sound would work in those situations.
ikr I saw a video one time that had all the different distances (feet, inches, ect) and there are like 100 that I doubt anyone has heard of. Anyway if you are going to round then change to metric of co its it will be inconvenient.
+MagickJam Fairly sure it's sarcasm. He’s saying each frame is 45 feet (a whole number) or 13.716 meters (an annoying fraction). Though he’s being highly unfair in this instance for multiple reasons. To start with, the speed of sound is variable depending on what it’s passing through and is not consistent in air (humidity and altitude, temperature and other particular content can affect it). He’s working under the assumption of 1125 ft per second, which is commonly cited but otherwise arbitrary starting value, as that’s a laboratory control example assuming it’s 20°C at sea level in dry air. The second issue is he’s basing the calculation on imperial to begin with, and then converting it to metric, which is obviously not going to carry over 1/1. You can just as easily get a workable number in metric if you start out there and say the speed of sound is, say, 350 meters per second (not unlikely in a warm environment) and that at 25fps that gives you 14m/s or 45.9318 feet per second. He is also taking the frame in PAL, in in NTSC (US) devices the framerate is actually between 23.976 FPS and 24, assuming the lower, since we’re talking about an older movie, then the numbers are 14.59793126459793 meters per frame or 47.893475277552262526 feet per frame. Neither one is “convenient” in this instance, but metric remains the scientific and world standard for a reason, even if the US and UK can’t manage to pull their collective heads out of their asses. The UK may be further along down the path of conversion then the US, but let’s not forget that some people still use stones as a form measurement. (Disclaimer, I am American, but have been using solely metric for the last decade)
Bullet noise is an interesting subject. As an LEO I get to shoot a few different firearms. On an MP-5 "German submachine gun" with suppressor, supersonic 9mm bullets actually make a small sonic boom as they exit the suppressor. Then another sonic boom as they go subsonic a few hundred feet away. Military style ball ammo tends to have a hollow base and these style bullets actually have a high pitched whistle as they fly down range. Since almost all military 9mm ball ammo is hollow base and supersonic you get both and it's not very quiet.
Lightning has to be the wordt offender in movies. The flash and the bang at the same time means you/your car/your house just got struck by lightning! You wouldn't be having a normal conversation just after..
I worked at Veterans Affairs and I recall a veteran of Tobruk describing to me his first encounter with an 88. He said that suddenly a neat 88mm hole was punched in the wall above and to his left (the round continued down range with a clump of cement on it's nose mad as a hornet) followed by a sound "like a Daschund vomiting" and what looked like the rooster tail wake of a racing boat of sand some 12 feet high coming straight in and slapping against the wall. The 88 was more than three times the distance that he could return fire with his 6 pounder anti-tank gun.
At least Saving Private Ryan did a little better with the sniper scene. You heard the crack of the rifle after the round hit Vin Diesel and the piano. And then you saw the muzzle flash before you heard the report of the rifle when the German sniper was killed.
as a Child I learned that when you see the lightning, Count until you hear the thunder, multiply by Three and get the how many hundred meters the thunderstorm is. it´s a good rule of thumb.
+Exploatores in america 5 seconds equals 1 mile for sound, so we just count until the sound hits us, divide by five and that is how many miles it is away.
I live about 25km from Sydney harbour. During the new year fireworks we can watch them on TV and a few minutes after seeing it on TV we hear the rumbling in the distance. It's actually really awesome.
I had ones in an RPG that I was GMing, descriped the situation that a character sees flash in a window, I asked the player what she wants to do, without teling her that is was the flash of the gun being fired. She didn't thought much about it, the I told the other players they see the bullet impact in her head, and only after that I told them they hear now the sound of the shot. The group became much more carefully after that, watching out for snipers and treat other people with more respect so that they give less people a reason to want revenge on them (since this was a revenge for something they did earlier). Good times!
You would see the muzzle flash first. Then the crack of the bullet breaking the sound barrier past your head, then hear the muzzle blast....Same with A 10 Warthogs providing air support for troops on the ground..You see the flash from the mini cannon and the plane diving quickly towards the ground with no sound...Suddenly big splashes of dirt start getting thrown in the air with still no sound. Soon after you hear the loud thuds of 40mm depleted uranium rounds hitting the ground at amazing speeds. ( the speed of the plane diving adds to the speed of the rounds impacting). Last you hear the ripping like sound of the cannon being fired from the plane. It sounds the sky is a piece of canvas being ripped all at once! Its one of the scariest sounds in the world in person
It's been a very long time since I've seen it, but if I recall correctly, Quigley Down Under did the sound effects this way. A rider would be shot, knocked down off his horse, and his buddies would be looking around for the shooter when you finally hear Quigley's gun firing in the extreme distance.
+The Business Cat Yes, show people reality, and they accept it. Saving Private Ryan's increase in sound accuracy improved sound in war movies in general.
Starving Poet Yes it does, just one of the many many reasons to love Serenity. Question on that subject, which was the best episode? I vote for Jaynes world
Always used to confuse me when playing more "realistic" video games (Arma, Battlefield, PUBG, Insurgency) when I'd be hearing what sounded like gunfire RIGHT next to my head, when in actual fact it was some geezer half a mile away with an MMG ;L It was actually whilst playing PUBG shortly after it came out that I realised that all along I'd been hearing the bullets and not the gun! I was sat behind a tree getting shot at by something semi-auto, and noticed that the loud crack I was hearing (which I previously thought were gunshots) corresponded perfectly with a more distant "thud" every time! Looked up "incoming gunfire" on UA-cam and sure enough, it was exactly that. Fascinating stuff and has massively helped me to ID and subsequently avoid snipers in video games (and hopefully real life if I ever happen to come across one ;L).
Other proof for the fact that the speed of light is faster than the speed of sound is the fact that some people can appear smart until they open their mouths.
I just love the feeling of distance you get in games like ArmA where they actually modeled the speed of sound (and the Doppler effect too!) Hearing the crack first and the echoing bang some time later just perfectly states that there is someone aiming at you 1500 meters away. And the same thing with tanks... well, if you see the flash, it is already too late.
I understand the complaint when it comes to long distance things, but I don't think it's really that important if the gunshot is nearby in terms of movie editing. It's the kind of think that only somebody who is specifically looking for that detail will notice, everyone else will be paying attention to what is actually going on in the scene.
The most I’ve ever experienced the speed of sound being slower than light was when I was in marching band, playing a song where the crowd would clap along. The director always had to tell us that we shouldn’t listen to the crowd’s clapping, as if we did, we’d be off time.
I remember reading that they tried making the sound realistic in the D-Day scene but it just confused the hell out of the test audiences. Also, in the Pelinor Fields (sp?) battles in The Return of The King the oliphants only have two footfalls and not four, as this also confused the audience. I tend to give movies a pass on these sorts of things, even if I am an easily annoyed pedant like yourself,
+Deinonuchus This isn't just pedantry for me. That sort of thing annoys me because it creates false beliefs in people for the sake of not confusing them. Why am I being treated like an idiot? How about confusing me for the sake of not lying to me?
Being shot at is very surreal. There's probably a million vids on youtube of real combat, but camcorders and cell phone mics never quite pick it up right and shooting on a range the lead is, hopefully, heading away from you. Imagine someone slowly scrunching bubble wrap close to your ears.* Seriously. That's as close to the real noise as you're likely to get outside of actually being shot at. (*NB: I accept no responsibility for hearing loss if you're stupid enough to actually try this.)
It's the cinematic equivalent to an omniscient narrator - you perceive everything in real time, regardless of how remote it is from the camera. I do remember a scene in _Saving Private Ryan_ where one of the squad gets hit by a sniper before you hear the shot, because that scene wants you to be in the action.
+CountArtha That's a very good point, actually. It helps establish the cause-and-effect relationship with an amount of intuitive immediacy. Personally, I don't think that's so bad - truly what our minds should be tested on in film is our predictions of what may happen, rather than trying to understand what happened.
Excellent point, as usual. One film that has stood out to me for trying to accurately portray the sound-lag phenomenon is Clint Eastwood's western, 'Joe Kidd. A marksman on a mountain perhaps a mile away fires at Kidd, and you see the ishot, then the impact, a couple seconds later, followed quickly by the crack. Maybe not absolutely precise, but a far more accurate representation.
So the REAL question is: In movies does LIGHT travel at the speed of sound; or does Sound travel at the speed of light? YEP, it REALLY is a whole different dimension... :)
+Fritzel Media Hold on there, Fritzel -- Speed and Frequency are two entirely different phenomena... Speed is velocity Frequency is wave length So, while your answer is "creative"; it runs afoul of basic physics... The Doppler effect which we perceive as the change in sound pitch results from a compression and lengthening of sound waves [compression = higher; lengthening = lower] but the speed of the sound remains unchanged. For example, as a train approaches you the sound of its horn is compressed because its movement in your direction shortens the sound WAVES; as it passes the sound waves are "stretched" as it leaves travels away from you; but at no time does the speed of the sound change. While my original postulation was a somewhat tongue-in-cheek question; the fact is Mr. Albert, is quite correct as you would NOT be able to make the determination -- at least with the parameters given. Speed or its lack is ALWAYS relative as it MUST be measured against some other value. This is why a car passing by at 70 MPH appears "fast" while traveling at 10X that velocity in an airliner at 30,000 Ft. seems "slow"'; and orbiting the planet at 17,000 MPH is like watching paint dry. Hope this clarifies...
I do appreciate when war films portray sound traveling realistically (though often they still don't do it with explosions, they do it with sniper fire).
The most recent episode of "Better Call Saul" got this right. Mike is sighting in a rifle and the camera is behind the target. You hear/see the bullet hitting the paper target and then a second later you hear the gunshot.
There are a few movies that get it right. For example, Quigley Down Under starring Tom Selleck. It's a western set in Australia. He plays a sharpshooter from the America who's been hired by an Australian rancher, who's played by the late Allen Rickman. Tom Selleck's character Matthew Quigley, fires a Sharps rifle. The movie shows a fairly realistic way, how skilled he is with this rifle. He's taking out bad guys from at least a mile away. In the movie you'll see the bad guy get hit, then a few seconds later you hear the sound of the rifle. There's a scene where he's demonstrating his skill to the rancher, by shooting a bucket that's been placed very far away. There's a shot in the scene, where you're looking at the bucket, and you're able to see where Quigley is standing at least a mile away. You see the muzzle flash from the rifle, a second later the bullet hits the bucket, and then a second after that you hear gun shot. There are quite a few scenes where they made a bit too unrealistic. Like men being sent flying when getting shot, but other than that. The movie is fairly accurate on how long range shooting works. It's great movie, if you haven't seen it. I recommend that you do.
Unless it's subsonic ammo, my preferred load for rabbits and I'm pretty sure the tommy guns .45 ACP would be subsonic too. I like the channel, you're like an English Skalligrim :)

Classic. Used to guess the distance of thunderstorms as a kid. See the flash, count the seconds until you hear the thunder, divide it by 3 (343m/s, 1/3 of a km) and you got the distance in kilometers.
Now in imperial:
375 yards per second, 1 mile is 1760 yards (eh, yeah), so that's a mile at 4,7 seconds. So devide your counting by 4,7.
It's just that the relations between the units are completly random, what makes it over-complicated. Not very convenient, isn't it?

Well, no. Not really. You can hear the thunders of thunderstorms miles (heh) away, before the storm even reaches your location.

That's the problem, lightning can strike miles away. Don't believe me? Here's the NOAA advisory: www.crh.noaa.gov/Image/gid/WCM/safety/lightning.pdf
Relevant information: Lightning can strike as far as 10 to 15 miles from the area where it is raining. That's about the distance you can hear thunder. If you can hear thunder, you are within striking distance. Seek safe shelter immediately.

+Zoey Chevalier ARMA also simulates the bullets. So normal bullets come with a crack while subsonic ammunition doesn´t have that. But they are slower and therefore have greater bulletdrop hence less range
SirStevetheCreep Right, I've played ARMA II and III, they definitely put more into the sound design.
"Metric is so convenient isn't it" From an Engineer's point of view yes it is.
I can confirm this.
+Nine_inch_Snails From a Physicist's point of view as well.
i'd get crazy trying to figure out how long 150*3/8 inches are in yards.
as a metric user it almost feels like no one ever converts or multiplies any numbers in britain or the us
firudu
Most people in the UK can use both metric and imperial.
+Penispumpenshop24.at I would say though that in everyday usage, Metric is a bit better, due to simplicity. Like a 1000 miligrams = 1 gram. Whereas with the Imperial system, it is kind of inefficient even for everyday use.

I do not know why, but when i've read this anecdote for the first time it made me laugh a lot.
It made me laugh to
Same here lol
At first, I read it as cows instead of crows, made me really confused.
I'm not sure it works. There should be no difference in order between the "supersonic" and "hypersonic" case.
@@madstofting9852 i Read cow to be I was like we have flying pig so why not cow
Saving Private Ryan even calls this out with their sniper scene; that one guy was shot and on the ground before you heard the bang (as even stated by their own sniper).
Yes like in all movies facts only matter when they suit the story.
@@Argoon1981 because there comes a point where you're just being a cunt about it
saving private ryan to my knowledge is the only movie that gets it wrong, but in the wrong direction
Based on how far that sniper was away it should have taken 1.2 seconds for us to hear the gunshot, we heard it after 3 seconds
Last episode of better call saul featured a gunshot with accurate sound delay. I just got home and I've spent my drunk evening thinking about that. Then I enter youtube and you've made a video about it!
+Marcelo Henrique I replayed the scene in Breaking Bad where a sniper's shooting at Gus's men. First you hear the impact with the woosh, then the sonic boom and the bang is the last in order. Incredible how they paid attention to such small details.
+Tallmios i just checked, they really did!
Whenever I see real footage of explosions, the sound delay gives me chills! It's so much more suspenseful and it gives you a sense of how big the explosion really was. I think it would be quite a revolution in film making if they capitalized on that effect.
Oh! This is most useful information at the tail end there! Speed of sound in chloroform is 987 m/s!
I'll remember that on my next date. I hope it will knock the girl off her feet in an instant!
She won't definitely hear that coming
the speed of sound through chloroform doesn't matter because no one will hear you scream?
Metric is convenient, but time units fuck with everyone equally.
Loving this 'regular uploads' business, it's fantastic to see more of your videos, Lindybeige.
I forgot to turn on my speakers and waited for a joke for the first 4 seconds.
Arma is a great game because the audio and visuals are very realistic for a video game
Wow... You slipped into an eerily accurate Alan Rickman there for a second...
+Plamen Dobrev
and he isnt even the bad guy.
In Lindybeige's UA-cam channel no one can hear you scream without Lindy making a video on how the sound you made is wrong.
By definition, an explosive fireball travels at more than the speed of sound; yet routinely in movies the protagonist outruns the flames.
+halnywiatr Not to mention the fact that convection doesn't seem to exist in movies.
And many times there should't be a long lasting fireball in the first place, i call movie explotions 'slow explotions'
Thanks mate that extra frame and a half really made the scene go from good to great!
in the new "Better Call Saul" episode the gun shot is delayed because of the distance :)
I've got a good one: medieval warrior physiques. They're obviously portrayed by bodybuilders in movies these days, but back then they didn't have modern gym equipment, nutrition, growth hormone, etc. I've always wondered this, and I hope you could do a video on it! Thanks!
Yeah, this effect is perfectly replicated in game ARMA 3, you can hear the sound crack, the sound travels at reaslistic speeds, really gives you idea how does it sound.
Interesting list of sound speed thru various materials Lindybeige, but to me the far most interesting is water :)
+Mikee CZ Another game that does it correctly is the Combat Mission series, from CM:Shock Force onwards. A pretty legit wargame, btw.
Strangely, in those games I found it a lot harder to accept what I was seeing/hearing, as it is a 3D wargame where you can move your camera freely so unlike Arma3 no avatar to channel your expectations of what you should be hearing when.
So games had me trained to accept sound to be instantaneously and to find realistically modelled sound to be strange. Thunder storms and firework shows were apparently insufficiently common to train my expectation level in games.
If we ever engineer ourselves to live in a vacuum hopefully we'll adjust our eyes to hear light so we can still listen to music.
4:08 I don't know about you guys but I find the silent flashes and the big growling that comes afterwards way more intimidating. Just step outside or open a window in a thunderstorm in summer and you just know what I mean! It is so RAD!.
my professor at the university always talked in sinister manner voice and with narrowed eyes, hm...
+Дмитрий Иванов Was his background music dark and brooding?
Lindybeige not really, there was no music at all. Maybe he was bad guy from old times, before sounds in movies
+Дмитрий Иванов In which case he could have brought in an appropriate pianist. Ha ha! In some of our lecture halls at the University there are ooooold pianos suitable to the task.. but so far no one has ever played them (except me.)
To put into perspective how fast light is compared to sound: if there was sea-level air all the way to the moon, and someone set off an extremely loud explosion there (maybe using a parabolic dish to get more of the sound heading towards you), it would take about a second before you saw the flash, but you'd only hear the sound (assuming it was still audible) a week and a half later...
+rmsgrey I"m not going to check your math; but that's a very cool illustration. I hope I remember it if my youngest kids or grandkids ever ask.
@@Albert4H passes the smell test
Light speed is ~300 000 km/s (in vacuum), the speed of sound (in dry air) is ~0.345km/s, so yes it would take a huge amount of time before you heard the sound of a massive explosion on Earth in the Moon, if sound was capable to travel in a vacuum, that it not and thanks goodness that it can't, because if it could travel in vacuum the noise from the Sun would kill us. Btw even tho light speed is so fast, it takes ~2.7 seconds for light (or radio signals) to reach the Moon from Earth and vice versa, so you would only see the explosion flash in the Moon 2.7 seconds after it happened not one second.
this is something I do in my editing when making my cartoons (if I have a long enough running shot) I'll delay far sounds. It really adds to the atmosphere :D.
great video btw :D
ha! Metric claims another convert
(C'mon guys, it's a pun)
+Dan Oliveira since when is metric a religion?
+Dan Oliveira That was sarcasm though
+Dan Oliveira Are you daft? The bugger was making fun of our glorious metric system, not praising it.
+Dan Oliveira That band fucking sucks.
+Dan Oliveira Unless you're being sarcastic, then you missed his sarcasm. This is why machines will always struggle with sarcasm.
When I was a young lad there was a sniper movie, "Day of the Jackal". In one scene, the sniper is taking shots at the intended target. In the scope you see the target moving about normally while he is being shot at. I, not understanding physics yet, was screaming at the TV all the while little plumes of smoke (indicating near misses on the ground) are seen. My dad had to come in and explain that the target was not being brave or stupid but rather was completely unaware of the danger. Many years later I was exposed to the remake. It was interesting how the two movies utilized sound The first movie used silence very effectively. The second was a Hollywood blockbuster.
+Ben Barker Even if the rifle is far away and uses a suppressor, you would still hear a very loud bang as the bullet fly next to your head. The sound the bullet makes is very similar to a whip crack (because the tip of the whip is also supersonic), so it is very loud and you cannot be unaware of it
Speed of Lindybeige in movies
I admire how your videos are still absolutely top notch with the high output you these days!
IIRC you can hear a bullet exactly at the time it whizzes past your ear. That is a different sound wave than the sound of the bullet leaving the barrel.
My dad, an artillery commander always told me if you hear the boom you know they didn't hit you. It's when you hear one whistling that you know they were close.
thanks
i really loved the addition of the speed of sound in other media.
keep it up, i'm liking the video output so far.
Being raised by a gunsmith and competitive shooter has ruined many movies for me. By the way, if you ever watch "Quigly Down Under" they actually take the speed of sound into account. A round lands and they wait for the report, then use that estimation to determine how far away roughly the rifleman is.
+David Stewart yes, probably one of the very few movies that take this into account..I was like 12yo when I saw it first time, and when the bad guy riding a horse gets hit and you hear the bang later, well... I was so excited that finally someone got it right that I talked about it for a couple of weeks
+David Stewart Great movie. The gunfight between Tom Selleck and Alan Rickman near the end was especially cool.
It's what immediately came to mind for me, too. I don't know how much else of the marksmanship stuff in the movie is accurate, but that was certainly gratifying.
And, frankly, exciting. That's something I don't get. Seeing a huge explosion at a distance, then actually hearing it several seconds later would make it seem even more impressive, to me. It depends on the situation, to be sure, but it can go a long way to setting a specific tone.
A movie example of this is is the original Red Dawn, when there's an explosion in the background during a scene which you see, but to which no-one reacts until the sound reaches them. It added a surreal, menacing feel, seeing it, and not hearing it immediately..
They got that right in Black Sails, the ships opening up flashed, then the booms came later. I was most pleased by that actually!
"...there will be a cone shaped area filled of sonic boom..."
*cue Guile's theme*
This is why I love DayZ and Arma 3. The supersonic cracks followed by muffled gunshots in the distance is a terrifying feeling.
One movie that got it right was "Quigley Down Under". In fact the bad guys used the sound delay to figure out the distance to the good guy sniping at them.
+bobobobinalong I think because of the ammunition and the range. The bullet had become subsonic by the time it had reached it's target. So there was no sonic crack.
+bobobobinalong Was going to point that out as well. Hell of a film.
One of my favourite films is Master and Commander, and there's a great scene where the French fire upon the Surprise and they do account for the sound not reaching the ship until much later. Perhaps you know the scene I'm talking about.
Anyway it really improves the whole scene a great deal. This is one of my own pet peeves too.
Good work Lindybeige, as always.
Wait, you took a ronded estimate of the speed of sound in feet, and then took a dig a the metric system when the resulting number converted to meters wasnt very clean? Kinda dishonest.
How about you took the rounded metric number, 340/s, which would give you 13,6 meters per frame, converted to feet it would be 44,6194226 feet feet per frame.
+MaMastoast Nice.
+MaMastoast my thoughts exactly - have an upvote!
+MaMastoast He's british, what would you expect? (jk, nothing against brits)
Stop. You're trying to reason with a fan of the imperial system, your efforts are being wasted.
+MaMastoast Precise conversion in either direction is messy. If you want easily handled measurements, don't convert, just stick with whatever system you actually used for the initial measurement (and, yes, LB has a prejudice here).
I really like that you provided video footage with the slight delay in audio. Even if they don't utilize the sonic boom you mentioned earlier I think that the delay between seeing the effect and hearing the sound actually enhances the film watching experience, it's a lot scarier especially when the camera is positioned from the point of view of the target.
Good guys: M16 Bad guys: ak-47
I remember there was a scene in True Grit (the 2010 version with Jeff Bridges) where one of them fires his rifle into a valley in which you hear the initial shot and then the echo a few seconds after it hit its target. It was kind of that scene that made me realize how sound would work in those situations.
4:28 Oh really? METRIC is inconvenient? Not the system based off the length of a grain of barley?
Minor grievance aside, really good video!
ikr I saw a video one time that had all the different distances (feet, inches, ect) and there are like 100 that I doubt anyone has heard of. Anyway if you are going to round then change to metric of co its it will be inconvenient.
+Crispy Bacon he said "metric is SO convienient"
***** Sarcasm, obviously.
+Crispy Bacon it didn't sound like sarcasm to be honest but yeah maybe...
+MagickJam Fairly sure it's sarcasm. He’s saying each frame is 45 feet (a whole number) or 13.716 meters (an annoying fraction).
Though he’s being highly unfair in this instance for multiple reasons. To start with, the speed of sound is variable depending on what it’s passing through and is not consistent in air (humidity and altitude, temperature and other particular content can affect it). He’s working under the assumption of 1125 ft per second, which is commonly cited but otherwise arbitrary starting value, as that’s a laboratory control example assuming it’s 20°C at sea level in dry air.
The second issue is he’s basing the calculation on imperial to begin with, and then converting it to metric, which is obviously not going to carry over 1/1. You can just as easily get a workable number in metric if you start out there and say the speed of sound is, say, 350 meters per second (not unlikely in a warm environment) and that at 25fps that gives you 14m/s or 45.9318 feet per second. He is also taking the frame in PAL, in in NTSC (US) devices the framerate is actually between 23.976 FPS and 24, assuming the lower, since we’re talking about an older movie, then the numbers are 14.59793126459793 meters per frame or 47.893475277552262526 feet per frame.
Neither one is “convenient” in this instance, but metric remains the scientific and world standard for a reason, even if the US and UK can’t manage to pull their collective heads out of their asses. The UK may be further along down the path of conversion then the US, but let’s not forget that some people still use stones as a form measurement.
(Disclaimer, I am American, but have been using solely metric for the last decade)
Lindy, you probably have some of the most creative and original content on this site.
Even his windows theme is beige.
Bullet noise is an interesting subject. As an LEO I get to shoot a few different firearms. On an MP-5 "German submachine gun" with suppressor, supersonic 9mm bullets actually make a small sonic boom as they exit the suppressor. Then another sonic boom as they go subsonic a few hundred feet away. Military style ball ammo tends to have a hollow base and these style bullets actually have a high pitched whistle as they fly down range. Since almost all military 9mm ball ammo is hollow base and supersonic you get both and it's not very quiet.
Lightning has to be the wordt offender in movies. The flash and the bang at the same time means you/your car/your house just got struck by lightning! You wouldn't be having a normal conversation just after..
+akumabito2008
Yes! That was the first thing I thought when I read the title of this video!
I worked at Veterans Affairs and I recall a veteran of Tobruk describing to me his first encounter with an 88. He said that suddenly a neat 88mm hole was punched in the wall above and to his left (the round continued down range with a clump of cement on it's nose mad as a hornet) followed by a sound "like a Daschund vomiting" and what looked like the rooster tail wake of a racing boat of sand some 12 feet high coming straight in and slapping against the wall. The 88 was more than three times the distance that he could return fire with his 6 pounder anti-tank gun.
At least Saving Private Ryan did a little better with the sniper scene. You heard the crack of the rifle after the round hit Vin Diesel and the piano. And then you saw the muzzle flash before you heard the report of the rifle when the German sniper was killed.
Awesome sound-effects of the sound-effect there "Lind"... I'm impressed. (no sarcasm)
The opening line is awesome. Great reference for a lot of movies points.
as a Child I learned that when you see the lightning, Count until you hear the thunder, multiply by Three and get the how many hundred meters the thunderstorm is. it´s a good rule of thumb.
+Exploatores in america 5 seconds equals 1 mile for sound, so we just count until the sound hits us, divide by five and that is how many miles it is away.
Which you can see works with the fireworks clip :P
I know this is a very old comment but dont you mean divide by three as in if you count to 3 its 1 km away
I live about 25km from Sydney harbour. During the new year fireworks we can watch them on TV and a few minutes after seeing it on TV we hear the rumbling in the distance. It's actually really awesome.
If you're completely deaf the speed of sound is so slow that it never comes.
Can't... resist... Your Mom joke...
I had ones in an RPG that I was GMing, descriped the situation that a character sees flash in a window, I asked the player what she wants to do, without teling her that is was the flash of the gun being fired. She didn't thought much about it, the I told the other players they see the bullet impact in her head, and only after that I told them they hear now the sound of the shot. The group became much more carefully after that, watching out for snipers and treat other people with more respect so that they give less people a reason to want revenge on them (since this was a revenge for something they did earlier). Good times!
3:26 "So how was work?"
You would see the muzzle flash first. Then the crack of the bullet breaking the sound barrier past your head, then hear the muzzle blast....Same with A 10 Warthogs providing air support for troops on the ground..You see the flash from the mini cannon and the plane diving quickly towards the ground with no sound...Suddenly big splashes of dirt start getting thrown in the air with still no sound. Soon after you hear the loud thuds of 40mm depleted uranium rounds hitting the ground at amazing speeds. ( the speed of the plane diving adds to the speed of the rounds impacting). Last you hear the ripping like sound of the cannon being fired from the plane. It sounds the sky is a piece of canvas being ripped all at once! Its one of the scariest sounds in the world in person

It's been a very long time since I've seen it, but if I recall correctly, Quigley Down Under did the sound effects this way. A rider would be shot, knocked down off his horse, and his buddies would be looking around for the shooter when you finally hear Quigley's gun firing in the extreme distance.
Great movie
The bad guys are easy to recognise. They have English accents.
Or russian
Nice to see you have taken note of the speed of sound in other media to. And not just movies. :)
I feel that if a film came out today with realistic sound, then it would get people talking and actually help promote the film.
+The Business Cat Yes, show people reality, and they accept it. Saving Private Ryan's increase in sound accuracy improved sound in war movies in general.
Thanks for the table of sound velocities. How could I have ever lived without that information? :P
Well said sir ! lets not even mention explosions in space in the movies........... they make me so angry!!!!
+Trigger Hippy Serenity does it very nicely.
Starving Poet Yes it does, just one of the many many reasons to love Serenity.
Question on that subject, which was the best episode? I vote for Jaynes world
I love Our Mrs. Reynolds, Christina Hendricks' character is one of my favorites.
***** agreed - I will also add that Gravity did do it quite nicely
Always used to confuse me when playing more "realistic" video games (Arma, Battlefield, PUBG, Insurgency) when I'd be hearing what sounded like gunfire RIGHT next to my head, when in actual fact it was some geezer half a mile away with an MMG ;L It was actually whilst playing PUBG shortly after it came out that I realised that all along I'd been hearing the bullets and not the gun! I was sat behind a tree getting shot at by something semi-auto, and noticed that the loud crack I was hearing (which I previously thought were gunshots) corresponded perfectly with a more distant "thud" every time! Looked up "incoming gunfire" on UA-cam and sure enough, it was exactly that. Fascinating stuff and has massively helped me to ID and subsequently avoid snipers in video games (and hopefully real life if I ever happen to come across one ;L).
Other proof for the fact that the speed of light is faster than the speed of sound is the fact that some people can appear smart until they open their mouths.
***** They look smart until they start speaking, I mean.. there's a million ways to say that I guess. whatever floats your boat.
I just love the feeling of distance you get in games like ArmA where they actually modeled the speed of sound (and the Doppler effect too!) Hearing the crack first and the echoing bang some time later just perfectly states that there is someone aiming at you 1500 meters away. And the same thing with tanks... well, if you see the flash, it is already too late.
I understand the complaint when it comes to long distance things, but I don't think it's really that important if the gunshot is nearby in terms of movie editing. It's the kind of think that only somebody who is specifically looking for that detail will notice, everyone else will be paying attention to what is actually going on in the scene.
Especially if it hits you absolutely killed me. :D Great video mate. Keep it up.
That's what I call an interesting piece of information!
The most I’ve ever experienced the speed of sound being slower than light was when I was in marching band, playing a song where the crowd would clap along. The director always had to tell us that we shouldn’t listen to the crowd’s clapping, as if we did, we’d be off time.
I remember reading that they tried making the sound realistic in the D-Day scene but it just confused the hell out of the test audiences. Also, in the Pelinor Fields (sp?) battles in The Return of The King the oliphants only have two footfalls and not four, as this also confused the audience.
I tend to give movies a pass on these sorts of things, even if I am an easily annoyed pedant like yourself,
+Deinonuchus Directors' cuts need this.
+Deinonuchus Pelennor. You make a good point!
+Deinonuchus This isn't just pedantry for me. That sort of thing annoys me because it creates false beliefs in people for the sake of not confusing them. Why am I being treated like an idiot? How about confusing me for the sake of not lying to me?
Please more videos like this Lindy. ❤
Being shot at is very surreal. There's probably a million vids on youtube of real combat, but camcorders and cell phone mics never quite pick it up right and shooting on a range the lead is, hopefully, heading away from you.
Imagine someone slowly scrunching bubble wrap close to your ears.* Seriously. That's as close to the real noise as you're likely to get outside of actually being shot at.
(*NB: I accept no responsibility for hearing loss if you're stupid enough to actually try this.)
Hearing loss being the Base case scenario! Maybe tryshooting past a good microphone instead? haha
It's the cinematic equivalent to an omniscient narrator - you perceive everything in real time, regardless of how remote it is from the camera. I do remember a scene in _Saving Private Ryan_ where one of the squad gets hit by a sniper before you hear the shot, because that scene wants you to be in the action.
+CountArtha That's a very good point, actually. It helps establish the cause-and-effect relationship with an amount of intuitive immediacy. Personally, I don't think that's so bad - truly what our minds should be tested on in film is our predictions of what may happen, rather than trying to understand what happened.
"When you see the flash, it's already too late."
;)
Excellent point, as usual. One film that has stood out to me for trying to accurately portray the sound-lag phenomenon is Clint Eastwood's western, 'Joe Kidd. A marksman on a mountain perhaps a mile away fires at Kidd, and you see the ishot, then the impact, a couple seconds later, followed quickly by the crack. Maybe not absolutely precise, but a far more accurate representation.
I... I did not notice the difference at the end. :/
+ruolbu I think that was the point he was trying to make; you can still have it seem intuitive and dramatic while having it be realistic also.
+ruolbu But did you feel the difference? Which made you jump more?
hmmmmneither? ^^
+Lindybeige I reacted more to the second one because the second one was louder.
Quigley Down Under did a pretty good job with this in a few scenes.
+Cassidy Eiermann
oh, damn that's right they did..
So the REAL question is: In movies does LIGHT travel at the speed of sound; or does Sound travel at the speed of light?
YEP, it REALLY is a whole different dimension... :)
+Carl Street Sound travels at the speed of light. It wouldn't make much sense for light to move slower lol
+Fritzel Media, But how would you be able to tell which phenomena was occurring?
+Fritzel Media Hold on there, Fritzel -- Speed and Frequency are two entirely different phenomena...
Speed is velocity
Frequency is wave length
So, while your answer is "creative"; it runs afoul of basic physics...
The Doppler effect which we perceive as the change in sound pitch results from a compression and lengthening of sound waves [compression = higher; lengthening = lower] but the speed of the sound remains unchanged.
For example, as a train approaches you the sound of its horn is compressed because its movement in your direction shortens the sound WAVES; as it passes the sound waves are "stretched" as it leaves travels away from you; but at no time does the speed of the sound change.
While my original postulation was a somewhat tongue-in-cheek question; the fact is Mr. Albert, is quite correct as you would NOT be able to make the determination -- at least with the parameters given.
Speed or its lack is ALWAYS relative as it MUST be measured against some other value. This is why a car passing by at 70 MPH appears "fast" while traveling at 10X that velocity in an airliner at 30,000 Ft. seems "slow"'; and orbiting the planet at 17,000 MPH is like watching paint dry.
Hope this clarifies...
I do appreciate when war films portray sound traveling realistically (though often they still don't do it with explosions, they do it with sniper fire).
The speed of sound in chloroform. Is that in pure chloroform or in chloroform drenched pieces of cloth? I need to know for... reasons.
+Lindybeige I love this video, i wish you would make more videos about film not fitting with physics in the real world.
Actually, the movie "Quigley Down Under" gets this mostly right.
LOVE THAT MOVIE!
Also the movie Way of the Gun
tyler harvey Highly under-rated movie.
David Townend VERY underrated! That movie is amazing!
The most recent episode of "Better Call Saul" got this right. Mike is sighting in a rifle and the camera is behind the target.
You hear/see the bullet hitting the paper target and then a second later you hear the gunshot.
Dammit Lindy stop defending the Imperial system this is not the dark ages
Quigley Down Under, did manage to get most of this right on the long distance shots that were shown from the target's point of view
If you're bashing metric system so much why don't you make a video about how imperial system is better. Would make a fine rant video I think.
That would be a weird rant since metric is de facto the better system.
There are a few movies that get it right. For example, Quigley Down Under starring Tom Selleck. It's a western set in Australia. He plays a sharpshooter from the America who's been hired by an Australian rancher, who's played by the late Allen Rickman. Tom Selleck's character Matthew Quigley, fires a Sharps rifle. The movie shows a fairly realistic way, how skilled he is with this rifle. He's taking out bad guys from at least a mile away. In the movie you'll see the bad guy get hit, then a few seconds later you hear the sound of the rifle. There's a scene where he's demonstrating his skill to the rancher, by shooting a bucket that's been placed very far away. There's a shot in the scene, where you're looking at the bucket, and you're able to see where Quigley is standing at least a mile away. You see the muzzle flash from the rifle, a second later the bullet hits the bucket, and then a second after that you hear gun shot. There are quite a few scenes where they made a bit too unrealistic. Like men being sent flying when getting shot, but other than that. The movie is fairly accurate on how long range shooting works. It's great movie, if you haven't seen it. I recommend that you do.
I wish you'd work in SI units :)
+Martin O'Donnell can everyone just please stick to base 10 units of measurement!
Unless it's subsonic ammo, my preferred load for rabbits and I'm pretty sure the tommy guns .45 ACP would be subsonic too. I like the channel, you're like an English Skalligrim :)
Favorite movies are the ones when you don't know who is bad or good, just all equally meh
+asoundlikesilence in reservoir dogs everyone's bad, apart from maybe that police officer
