Forensic audio research about the sound of the planes that crashed into the WTC on 9/11. This is not a real recording. The only real sounds used are some of the engine sounds, and the actual WTC 2001 Alarm System Cerberus Pyrotronics MXL-V.
This is a "fictive" recreation. Multiples sources have been combined and enhanced. A complex work of foley and sound design has been done to create a realistic audio file. This is what the shaking core, impact, explosion, debris, fire and alarm system potentially sounded like.

Thank you for the support, more to come!
First 🥇🏆 to reply here. XD
O.o :3 Imagine in 2031 the Freedom Tower gets hit and falls down [with b*mbs again]. The owner of the land wanted to do replica Twin Towers, but they agreed on one tower, and a memorial. Hopefully, no one falls down that hole where the water goes. The Freedom Tower is even larger than one of those original Towers [that I saw in my middle school years, and I'm from Florida, but I thankfully left Miami, FL, and America lol].
@@ReligionAndMaterialismDebunked They're planning a World Trade Center Two tower.
That silence before the sonic boom impact is probably the most creepy
I can imagine it would've been far far louder.
After a month, my judgement changed, I also think It would have been louder and longer.
Turn your volume up as far as it will go.
@@forensicresearchit would have been deathening if you where near the impact
This sounds like it would come from a sky lobby elevator. The explosion at the impact site would have been a violent, heavy slew of white noise.
@@forensicresearchwill you make a remaster?
So eerie. Especially the creaking of the swaying afterwards. Great work. Imagine emulating the sound of the collapse next! :0
Thank you for the comment and positive feedback. I planned to work on the collapse. It will be complex but not so many videos give justice to the explosive and massive intensity of the sound that the event caused, It's definitely worth trying.
If I remember correctly, FDNY survivor #JayJonas compared the sound of the North Tower collapsing above him to a bowling ball rolling down the stairs.
@@forensicresearchthere’s a 911 phone call recording of a man during the collapse. It’s very disturbing, but it’s what you’d basically expect: a bunch of loud, poor quality rumbling followed by silence.
@DakotaTNWX0330Not to minimize his horrific experience, but the buildings fell in roughly 10 seconds. That would have been 9 floors collapsing a second. Wouldn't it just have been a massive roaring or rumbling sound, not so much individual pancaking?
@@kevinsmart2165I would tend to agree, yes
The Twin Towers were the most perfect buildings for a world without terrorism. That was their flaw. No other building in the world will produce a view like Windows, it really is like being on a plane in descent how high up you are, the lush red and orange velvets of the carpet and furniture accented by the natural sunset.
It's hard to imagine how it would've felt being a chef or waiter up there, and watching a plane fly and crash *underneath* you from there in what is supposed to be a secure and sacred place.
Thank you for the comment. You're totally right, these buildings transmit some sort of peaceful atmosphere.
@@forensicresearch The entire concept of the World Trace Center was world peace through trade.
Worse yet the tower were ready to withstand an attack almost exactly like 9/11, but in 1960s-1970s planes. It was said they could withstand impacts of 727s and not collapse, 767s are unfortunately much larger.
I found the towers extremely unpleasing to look at. Just giant blocky concrete slabs
@@noidea8590 they were awful looking and new yorkers also thought so. they were def a symbol but not too pretty while being one
The quick pause between the sound of the engines and the noise is very reliable. the sound everyone heard was the explosion and not the impact. The video captured very well that the plane ceased the noise of its engines as it disintegrated on the facade of the building and then exploded inside.
Also when the first plane impacted the North Tower, fuel travelled down two of the elevator shafts and exploded on one of the lower floor’s sky lobby and in the ground floor lobby too.
Yeah someone who survived said he forced one open to try and find an escape and he just saw a pile of corpses who were in the elevator when the fuel exploded
If you believe that you’re an idiot. There was only one elevator shaft then went all the way down and the plane didn’t impact it
@@Elbowbanditest2003 That would be extremely creepy and horrifying to witness.
This was recounted by a survivor who said she heard a second blast when she was down in the lobbies of the north tower. She didnt elaborate on the second blast and it always left me wondering. Now I know what it was.
@@KevinTR96nah a lot of people reported hearing second blasts while they were in the lobby, but there is footage from firemen (from inside the lobby) that makes it clear that it wasnt explosions they were hearing... they were hearing the jumpers hitting the floor
There is actual, recorded audio from WTC 3, the Marriott, ground level, in a restaurant. An FBI informant was wired so the recording includes the FBI intro with date and time, him walking to and entering the restaurant, and the first hour and a bit of his breakfast meeting with the person the FBI was investigating. There is live piano music and happy chatter of other diners in the background.
This restaurant faced out into the courtyard and was basically wall-to-wall glass including the roof with a view upward of both towers.
At the time of the north tower impact there is a faint boom and he says “that sounded like an explosion!” Then all hell breaks loose. An extremely loud and continuous WOOSH of debris hitting, and the blast and fireball hitting from above along with the fire alarm whooping and people screaming and running hits. It’s way, way louder than this!
Then he makes it out onto the street. Still loud but with fire engines arriving-sirens, air horns, people’s astonishment as people start jumping-and THEN the 2nd plane hits. THAT sound is *deafening*, from the ground more than a block away!
The towers collapsing has been described by those right there as sounding like “sitting on the runway of an airport surrounded by jet engines on full blast”. So, very very loud.
The noise after the 1 explosion is the noise of the mic touching the clothes while the holder is running - not the explosion blast.
I can't even imagine - You're sitting down with a coffee and breakfast at your desk ahead of your 9am meeting with your biggest worry being that you'll screw up during the meeting. Then, it turns out to be the last hour of your life. God rest their souls!!
Imagine being the person who called in work , on vacation or was running late that day. I know I would have had really bad survivors guilt.
Rest in peace to those who died
So sorry to their loved ones
My respect goes out to them
Thank you to those who tried saving another life during this 🕊🤍
Including firefighters and police officers, nurses, doctors 🕊🤍 so much more
I saw you on that New WTC fire alarm test video lol
This is a great recording - I would suggest a follow on version with a simulation on the video of the effects of the tower swaying from the impact... Keep up the good work.
Very intense. I can't imagine the terror people endured as they tried to flee to lower floors as the planes hit.
A lot of people didn't know what was even happening. They just found out after they got out or someone told them.
It’s a good recreation but it would of been interesting if there had been some sort of recording that survived among the rubble somehow but obviously impossible. RIP to all the victims
This sounds more like a drone crashing into the wtc than a passenger jet. Even from the ground, the shoud was like a loud, sonic BOOM. And people in 2 WTC reported the building moving several feet to one side before "slowly springing back to an upright position". So more work needs to be done, but great incentive and great video nonetheless.
The impact would’ve been a lot more acoustic and raw than you can hear. The impact wouldn’t have been subdued and you would’ve most likely heard the metal crashing and impacting more than an explosion because of how sound waves work. And a LOT louder which means you wouldn’t actually hear what you’re hearing it would sound more like you were in a supermarket where every shelf around you fell
Cool recreation! Far better than what I could do, however it did feel a bit anticlimactic. I would expect a much larger and louder explosion and also I imagine the sound of the plane approaching would be louder too
Turn the volume up as loud as possible and hold it up to your ear. That’s about 1/2 of how it sounded
Depends. When the hijackers on the 2nd plane were approaching, they sped up. From what I can recall from experiencing being somewhere where war was declared, I never heard the jets until they were almost right above me, it was so quick. Went from nothing, to suddenly thrusting engines. Still have PTSD when hear planes make a certain sound, and this year is the 10th anniversary of that experience. Can't even imagine the trauma 9/11 survivors feel when they hear or smell certain things.
This doesn't do ANY justice to what the actual sound must have been like. I'm quite sure it was FAR FAR louder and aggressive.
Depends on what floor you’re on. In an actual recording of the event the explosion from the outside is barely any louder the plane’s engines. You’d prb hear a huge crash tho and also feel something too. Scary af ngl
Bone chilling shit my man, phenomenal job!
Thank you for the comment and positive feedback.
Very interesting, would you provide more insight into how you created this audio? Does it take into account the creaking of the buildings as the swayed back and forth a few times due to the impact
You can hear the sway (better with headphones)
Using the time between the first hit and second tower hit would be more accurate as well as fire alarms going off in the distance. But other than that i do feel bad for the victims that went through the attacks, it must have been horrible to see a plane hit floors below.
That’s the scariest thing I ever heard, the loud explosion following what I would assume is the destruction of the steel frame, followed by the eerie alarm, and then with screams. I cannot imagine how terrifying that must have been.
I can feel my goosebumps on my arm when I'm listening to that 😮
Excellent work. This is a great idea as well for some video editor to edit a plane coming in and hitting the building with this sound. I would feel very realistic..
Thank you for the comment.
That's the real audio is not edited
This is chilling. After 22 years I thought i’ve seen it all & now this.
I can just imagine being on top of the Twin Towers way before 9/11, the view has got to be AMAZINGLY BEAUTIFUL. Wish I’d seen it
Horrifying. To know that your fate is sealed is monstrous.
You've done a hell of a job here
Thank you for the comment and positive feedback.
About what floor would this be heard in
Thank you for the comment.
Since this is based on the South Tower Impact sound, I would say floors around 50 to 75, under the impact zone.
If I had to precisely guess I would say 60 because of the falling debris / fireballs and because of the overall loudness. But since this is an impressionistic take on the matter and not a fully scientific sound recreation I can't be sure. Now that you've said it, i realize that if you were around the 75th floor the sound on the spot was potentially much louder and much more intense. However, if you were low and isolated enough (for example pretty far into the emergency stairways) it would have sounded quieter, like some sort of quiet but "bassy" thump, which wouldn't even alarm you. What could be interesting would be to define the state of Cerberus Pyrotronics MXL-V Alarms. Did they really work after the impact? If they did up until which floor the system would be destroyed? I haven't done this extensive research to be honest, I definitely will for the next works. If you have any suggestions feel free to tell me.
@@forensicresearch thank you, the sound is very accurate to me. And unsettling. As for suggestions maybe you could do the sound of the jet fuel going down the shafts and exploding into the lobby
@@forensicresearch Can't 100% remember, however If I correctly remember, the system was cut off from impact zone and above, other than that, the system was siren only and the fire warden would make announcements for dedicated floors. Not quite sure if the system was silenced then resumed as you can actually in some of those released lobby videos hear far in the fire alarm speakers being activated randomly, you can also find higher quality images zoomed in the fire control panels at the lobby which shows alot of lit indication lights, the system at the time did indeed print logs of the alarms which i'm not sure if you can but should be almost visible in some clips, however these are of course physical tickets and got most likely destroyed upon collapse
At first I thought this was going to be one of those 24/7 relaxing music videos.
Wow. Great work. Just like they are doing with Titanic, imagine if 9/11 was recreated using unreal engine 5
Thank you for the comment. I'll keep uploading. If you have any suggestions don't hesitate. There is someone who is working on the WTC Complex with Unreal Engine, Dante Sanchez on TH-cam I think. The sound would clearly add to it. I chose not to include human elements because I didn't want to create some sort of sensationalized work, I tried to be factual and neutral. It's something to think about when doing these projects.
@@forensicresearch Got some suggestions.
Brian Clark was a survivor from an impacted floor. He described the sound of 175’s hit as a “Boom-BOOM”. Southeastern camera views of the hit can corroborate this double boom, just below half a second between each boom. I would further louden and emphasize that first boom, or make it a “BADUMP” from the nose/wing/tail impacts, also heard in southeastern camera angles.
I should also note that in Scott Meyers’ 175 footage, the building started shaking immediately when the plane hit, not when it exploded as this recreation entails. So perhaps start making clattering noises at the first boom.
The building interior core swaying noises and falling debris are perfect though.
@@scheldon2244 Thank you for the comment. I also noted the "double boom" while recreating this. In this video, if you listen carefully, there are 3 different impact segments, the first one is a muffled thump, the second one is a metallic ex/im-plosive one, the third one is supposed to be the heat from the explosion reaching to the floor this would have been recorded on, and bursting through the ceilings + doors. I could try to emphasize the time that passed between these 3 segments, to be more factual and less artificial. In the 3 videos that I have posted (except maybe for the first one which is synced to the footage so not so much impressionistic freedom was left) the time between the two booms has been shortened because I felt it didn't bring justice to the actual power of the situation, it felt weaker, but it wouldn't be uninteresting to rethink this through. For the shaking part, you're probably right. Thank you for the suggestions and positive feedbacks.
We need to wait until it stops becoming disrespectful
@@the_mariocrafterIt’s disrespectful to think that way honestly,
Dark humor is gay and evil, so is the new Rewritten Complex
This has got to be one of the most terrifying sounds albeit a recording.
Like many say the actual impact would be tenfold. An Unimaginable sound and feeling.
Can’t imagine the fear and confusion these poor souls had to witness first hand.
#Neverforget. God bless those who perished and those who rose to the overwhelming scenario. To name a few FDNY NYPD NY Port Authority,Countless medics,nurses and doctors & Lastly the people of New York.
God bless America.
From a great ally one to another across the water. 🇬🇧
Horrifying, literally got the chills! You did an amazing job. #NeverForget 9/11 🇺🇸
Thank you for the comment and positive feedback.
Apparently, this is a real audio recording of the events, recorded in 3 WTC as Flight 11 hit the North Tower, th-cam.com/video/tA6dFHeo-8o/w-d-xo.html
This sounds very similar to reality, almost. I've never heard anything like it.
Really interesting, thank you for sharing.
1. Loud explosion. I'm currently in Ukraine and trust me, explosions are pretty loud inside the building. Especially with direct hit.
2. Screams. I know that you would like to share how quite it would be, but you need to consider that a lot of people were inside.
3. Debree. I do like how you added falling debree at the start, but it was actually falling non stop. Just way less intense
Other than that
They said it is from the inside of an empty WTC building
Debris

I hate all natural languages for this stuff😅
Gonna go learn Spanish lol
@@andrewsemenenko8826 i heard spanish words are pronounced like they're written and letters don't contastly change

@@TheBobmaker yeah.
I was once learning French and almost had a stroke with it. 😅
And I was like "hey, isn't Spanish a Romance language too? Let me see it for the gags"
Just imagine my shock when I saw the same words as in French, but you read them like a normal person😂
Instead of voweling every letter you see without any rules whatsoever lol 👀
Intrresting sound. The somewhat muffled character was unexpected, but makes some sense if heard from one of the floors which weren’t directly hit..
I like your content, subbed
Thank you !
@@forensicresearch where are your other videos?
@@RIPzippyshare in private.
@@forensicresearchdo the wtc collapse sounds
Never forgotten that sound still haunts me
Thank you so much❤
the only thing i would wonder about this that your video didn’t cover as much - do you think it have reverberated through the structure for a while, at least initially? like the sound of the tower, ringing like a bell (not that it would sound like a bell). sorry i’m half asleep so i hope what i’m trying to say came across.
I thought it would be so much louder, almost deafening, I was holding my breath waiting for it in anticipation of it making me jump. It makes me wonder, if the noise from the impact had indeed been so much louder, would the people in the buildings have had more of a sense of immediate urgency to get themselves out of the buildings? We will never know, but it chills me.
This isn't the actual sound, the real sound was WAY louder. Several in the nearby floors reported losing hearing for several minutes after the impact. The building also moved 12 feet over when hit, which was described as feeling as though the tower itself was collapsing by survivors. Believe me, once the plane hit, the people in the towers had all the urgency in the world to leave.
@@hippo440 Jesus, I can’t even begin to imagine how terrifying that must’ve been. And the building moving 12ft, dear God.
So many people in the second tower started evacuating despite orders to stay. Firefighters that made it far up reported seeing that multiple people had been decapitated whilst waiting for the elavators. Makes me so angry with security telling them to stay. I understand not wanting to cause panic and a crush but I'd rather be stuck with hundreds of people around me in the stairwells on the lower floors than up there in the sky where I'm even more vulnerable. Plus there were multiple exits that security could have let people use that would have taken them straight under and away from the complex.
I remember the recording of the young man who was only 24, he sounded very calm and told his mum he was safe and he’d be leaving the building! How sad!😢
Wow the fire alarm system in the background makes it even more creepier
Why are there two separate reports: at 0:11 and at 1:08?
Какой ужас, страх!
Сочувствую Америке!
Очень Жаль погибших людей! Башни-Близнецы Превосходны! 😢
My entire school shook when the plane hit the pentagon my desk literally bounced in the air when I was in elementary school and lived in Arlington Virginia so if my school shook then I can only imagine what being in the tower would feel like.
People inside the upper floors describe the noise as being extremely loud & the building swayed way over & then back.
If this audio was (presumably) from the 1st tower that was hit, and it was below you, then you’re already dead. The planes impact took out access to the stairs and elevators above the impact zone. All those who were up there had no way to escape besides…well…jumping..
If this is the North Tower, those alarms actually killed more people. The alarms told people to remain in place. One gentleman started to leave immediately with his coworkers. They were located just a couple floors below the impact zone. He decided to ignore the alarms and continued down the stairs. His coworkers didn't, they turned around and went back.
He survived. They all died.
I do not have any programming knowlage but I have an idea for a WTC game, if I did have the knowledge I would try and make it as respectful as I could. It would be intresting to know what I would be like in the towers when the first plane hit.
Even though I am sure this is not even close to as loud as the impact actually was, its still creepy as crap.
Cualquier otro edificio se hubiera desmoronando inmediatamente, pero estos no, estos vencieron a la gravedad y aló imposible durante largos minutos
Thank you for the comment. Yes totally, it is surreal.
Этого никто не узнает ,но взрыв, взрывная волна, была внутри неимоверной силы, здание однозначно пошатнулось, такая масса залетела на такой скорости Боинг
Imagine If You Were Trapped Above The Impact ? You Might Have Just Been At The Exact Impact For It To Be Over Or Underneath To To Get Out Before The Collaspe
figure out how to properly write spaces
Use earphone this is so terrifying can't imagine the day 9/11 happend.
Amazing work. You should make an extended version
Thank you for the comment, what do you mean by extended version?
@@forensicresearch A continuation with the emergency broadcast playing, along with the creaking/other sfx
That is the real audio bro !!
@@rolandoosegueda6343it’s not the real audio. No audio from inside the towers has ever been released (except for lobby footage)
@@rolandoosegueda6343 it quite literally says it isnt.
amazing work but must have been terrifying
Very nice work!
With literally thousands of security cameras on premises, a recreation is all you will ever see or hear.
The WTC security center located in the towers watched cctv monitors live so there wouldn't have been any recorded anyway.
All elevators or something like them need to be located on the exteriors of any high-rise building. Also said buildings should be built with helicopter rescue access on rooftops also swing out arms for parachute escape. All personal working in buildings tall enough must have parachute training proficiency. I know this will not set well with some but just remember 9/11. I would take my chances with a chute then smack a sidewalk at 130 mph or burn alive up there. Those who died above the impact zone were completely helpless and nobody on the ground could do a blasted thing to get them to safety. The buildings design deficits were clearly made evident. Building engineers can do better. .Its like sending cruise ships full of thousands of people to sea without lifeboats or even life vest to wear. Building safety still remains in the dark ages. How many more must parish in these death traps before better means of escape are built into high rise buildings? I understand there are cost involved. Put them up as cheaply as possible and run the risk.. There has to be a better way .
That would have been a lot louder than this!
The words to the fire alarm are TERRIFYING!
I don't really get why you didn't mention where, relative to the point of impact it might have sounded like this? On the one hand it sounds not especially close, but on the other, almost as if it's on one of the floors that were hit because of an apparent sorta windy "there's a big fucking hole in the wall of my skyscraper" sound. In general I was kinda eh on it, but somehow the 2001 tape emulation sound seemed much much better to me, the first few seconds of it anyway. At least it sounded like videos of the impact from the time, not that most of them were super close.
You can read the answers I gave to the other comments to know more about the process. Thank you for the comment.
I agree.
So was there any footage or documentaries about the Marriott world trade other than 1
I can imagine it was more louder than this
Why do I click on these types of videos? This is a living nightmare
Please make a version with louder impact
Photo from the WoW.
the fire alarm tone in fact played only the whoop tone heard at the beginning, not the voice message. the only time a voice message would be heard is if someoen was speaking over the PA system, which the fire alarm system had a PA system in it,
Why is there a moment of silence before the explosion?
Thank you for the comment. This is in fact shorter than what it was described to be like by the witnesses, the fuel exploded after the plane bursted into the building, there is also a third segment / pause before the explosion delivers its sound, simply because this is supposed to be a recreation of the sound under the impact zone. The debris and fire came in progressively, I tried to recreate this sound, this is why it sounds somewhat different than the videos from outside, where no "progression" of the fire would be heard. I hope you see what I mean.
This is probably what it sounded like from about 5-10 floors underneath the impact zone.
Jfc this is spooky. I had cold chills.
Sounds too quiet, it would have been better if it was louder and more violent but overall great work
Thank you for the comment and feedback. Depending on the floor, the sound would be so loud that it would temporarely deafen you, if you listen to this work on the maximum volume while keeping in mind that this is supposed to illustrate the sound a dozen of floors under the impact zone, I think you will feel the violence of the impact. It's delicate to recreate something like this because the loudness of a recording is relative to the input volume of the recorder, if hypothetically the recorder volume knob was on 1db when recording the impact, this wouldn't sound too quiet, I think it wouldn't distort. During the second part of the video, the tape emulation shows how the actual loudness of the sound would cause clipping. Not to say you are right or not right, just to try and explain that obviously, the sound on the spot probably was much more violent and potent, especially if you take into consideration the fact that I excluded the human sounds, because It would simply be graphic and not so intelligent in my opinion. I have to say, loudness is an interesting and complex aspect of these recreations, how to make something sound louder without clipping / enhancing the volume / while at the same time not being too cinematic by adding bigger and bigger explosion sounds? It is a challenge to define in some "artistic/artisanal" way what the right amount of fiction and science has to be. I'll work on it.
Meu corpo arrepia ao primeiro som!
More deep rumble, less clanking. The floors and window interiors were concrete, and people were thrown. 😢 I think the second is more accurate. Haunting work.
Never forget RIP to the victims from Greece
0:11 1:09
Wow
That plane hit was deafening, there has been reports of victims actually going momentarily deaf....Way Louder Than
Chilling...
This is terrifying.
the cinematic affect they add is dumb. from those inside they heard nothing and then a massive explosion, and while the building shook them to their knees. no rattling of metal pipes or what ever. no alarms simply the loud explosion and for those close to it they heard the fire crackling.
1:00
Where is this office supposed to be, on the ground floor? Doesn't sound very loud. And if it was on the ground floor, the sirens are too faint.
Yet almost everyone who was in the building when the planes hit never heard a plane, just an “explosion”
where are your other videos?
The explosion sounds just like the one that was recorded by jules naudet.
I think there was more time between the impact and the alarm that going off
Wow.
That’s just scary
Alarms?
Sounds like someone dropping a bucket of bricks down a ladder.
El primer choque, sí sonó muy real 🥺
Good ASMR
I gonna report you if you don't stop saying bad words.
What bad words????
oh shit
Bruh that sounds like someone hit a wall with a baseball bat
This actually gave me a vision of the experience and I am forever traumatized by it..
Horrifying 😢
I honestly think it sounded way far louder and way more aggressive than this. Survivors have described it sounding like a large bomb going off, followed by aggressive swaying and shaking of the floors they were on. This audio does not really capture that.
vine boom sounf effect
This sounds like its from half life 1
