What was the name or number of the plane that hit this building? Flight ....

The voice on the first alarm is chilling: “A fire emergency has been reported in the building.” Given that the buildings were hit by 767s and roughly 10 floors were on fire, that’s an understatement. It’s crazy to think that some people towards the bottom didn’t feel the jet impacts and the electricity, water, telecom, etc., continued to function. That’s how huge those buildings were.

@AA The chime sound was there to notify about a fire related incident whereas the whoop signaled evacuation. Firecom still provides the alarm system for the current WTC complex, and there's a video in which someone films the alarm going off within the transportation hub. Albeit a slightly different tone due to it of course being a newer variant, Firecom still utilizes it. There were no alarms associated with the destruction of buildings as such since not only because such scenario's are too specific, it would also defeat the purpose of what an alarm is for; to notify about ongoing hazards within the confinement of the building itself. WTC 7's alarm got triggered after the collapse of the South Tower, presumably due to the vast amount of smoke entering the building. Lastly, the chime sound can be heard within Mark LaGanga's video of WTC7's lobby. The North Tower was still standing at that point.

I came here after hearing the WTC7 alarm in some documentary footage taken shortly before it collapsed. That sound is... creepy, unsettling, haunting. The part with two beeps is the creepiest part for me, for some reason, but the whole thing fills your soul with dread.. I've never heard an alarm like that before. Nor have I ever felt compelled to look up an alarm sound until this one.

@PygmalionFaciebat

8 ай бұрын

I think thats on purpose. Sure everyone knows thats on purpose, but let me explain further: i think the one who designed the sound, knew, that New York is filled with a lot of sounds, noises, beeps, etc.. So he had the hard task to design a alarm, which not only distinguish itself by every other possible sound in New York, but also sounds so much serious and horrifying, that everyone in that building would take it serious immediately. The sound sounds so easily designed, but it isnt. Not only the pitch is very well choosed, not to low, not to high (its in the sweet spot of the highest sensitivity of the human ear . The ear is less sensitive for higher notes, as well as for low notes). The 'attack'' (first 100 ms of the sound) is also very well choosed, which makes this ''hammering'' noice in the beginning of the beep. It literally alarms the body , because of that hammering uneasy feel. The sound designer also choosed a sawtooth-waveform, which in a subtile way differs from a piano-note. Also the rhythm of that noise is in the pattern of a heartbeat, with a long release-phase (like an echo or reverb of the noise). Everything of that sound is made to take actions, way before people smell smoke, or see fire. Its really very intelligent psychological sound design. Thats why in the comment section a lot of people point out that sound, and describe it as creepy , eerie, etc.

@@PygmalionFaciebatThat is a very good assessment of this alarm. I also was thinking something very similar to what you were saying about how it seems simple, but someone probably put a lot of thought into its sound, and did so intentionally to better establish a sense of urgency when it sounds. This is probably the one alarm people would hear and actually think twice about it (except for just finding the alarm annoying). I've seen typical alarms going off in public places like malls and even airports and they just are ignored. It's so a-typical of an alarm you'd never forget it. Also notice how it's not ear shattering loud like almost every alarm, the two people are able to have a conversation without the alarm over stepping them. Quite a fascinating thing, but I could also just be overthinking it. Would be interesting to hear from the people who designed it where the idea came from.

In the longer version of Melissa Doi's phone call to 911 there are moments in which you can hear the fire alarm in the background. So glad the dispatcher stayed on the phone with her to the end.

I can hear that ping sound at 1:30 in a lot of documentaries and I had no idea it was only for building 7. I thought it was coming from building 1 or maybe 2

Here in Brazil, my completely desperate grandmother picked up my mother from school, thinking that this could happen here in Brazil. My father still lived on a farm, he was in a local business watching on a small television, all the news being interrupted to give the news that a plane had collided in WTC 1. Soon after, my father reported that he saw the second aircraft hit the other tower. And so it was for the rest of the day, following everything about 9/11 in 2001 on that commercial television my father was on... It must have been something shocking to have followed that. I'm very excited about all this, it gives me something inside me, I've always been one to research and find out more about 9/11. We can say that since 2001 until today I have been very interested in looking for everything about this regrettable event. Whenever possible, I always watch videos, read articles from the USA and Brazil about the event, I go very in-depth about it, and I always look on the internet for possible things that remain from 9/11 today. This interests me a lot. Hugs here from Brazil💪🏻

Regrettably, prior to 9/11 no one would foresee a second impact in the South Tower. I've noted in the description that despite the complex being one large superblock, each building was independently controlled. There's a sound file somewhere that did indeed declare the situation in the North Tower under control and thus ordered all occupants to return to their offices. In hindsight, that automated notice was another fatal addition to the tragedy. Not only could the South Tower have been more empty, I recall it caused a massive holdup in the stairwells due to people moving in both directions.

I said "I'm going home, this is a danger can't you see that it's on fire?!" They made me change my mind and went back to my office on the 56th floor, then the plane crashes into the upper floors, now the second fire alarm kicked in again but it was different. A Port Authority officer said "GET OUT NOW!" I never saw him again but he saved my life. It wasn't the same officer who prevented me from leaving the Trade Center.

I received this at 9:01 AM. I was already at the main corridor ready to leave to go home. Two minutes later, everything around me rumbles, Building B is hit. I heard a low flying plane at the time. At first I thought it was a coincidence that both buildings exploded due to some sort of accident. They officially told us to evacuate when the South Tower was hit and by the time it was hit, I was already in the 23rd floor, when I reached the main lobby, I was running out and then this guy broke his leg trying to run down the stairs. I reached out and tried to help him, he said "My nephew... my nephew is up there." I asked where and he said "the 83rd floor." I was shocked to hear that and then he asked if the fire department can save his life and rush to the upper floors. We got out of the WTC complex and we kept on going until the Empire State Building. By the time the firefighters reached the 83rd floor and we reached the State Building, from there we watched the South Tower falling. He watched his nephew perish along with the others as the tower tell. He froze for two seconds and then started praying for him. 8 hours later, they found his remains....

There is one quite eerie video on KZread, might be unlisted, called "Inside 7 World Trade Center Moments Before Collapse", and you can hear the 8500 system chiming and whooping away throughout a good chunk of the video. Sounds are spot-on. Maybe just a difference in timing, like you mentioned in the description. I have wanted to recreate these sounds for some time to use in a possible simulation system setup, but I don't know what program I would use to do it, much less how to do it. Great job.

I appreciate it! The video you're referring to was shot by Mark LaGanga, which provided a rare account on the trade center site in between collapses of the south and north tower. From what I could gather from the Firecom patent, the alternation between the whoops and chimes was regulated through circuitry rather than being a fixed sound file. That might explain the varying duration of it as heard in LaGanga's video. You can even hear the whoops either being cutoff or starting midway a repetition.

As cleverly noted by user Datamaster, it turns out the Firecom alarm was added into that video in post. I've overlapped the audio with Mark LaGanga's WTC 7 footage and not only does the alarm sound overlap perfectly, I was able to distinguish other background noises from LaGanga's video that were present in the WTC 5 evacuation video as well, at the exact same time also. He had also pointed out that in between videocuts, the chime sound continues uninterrupted. If it was an actual recording that would coincidentally overlap between takes, there would be at least some form of an audio cut. And to think of it now, it actually makes sense that the audio was edited in later, because the chime sounds signaled a notification of the fire department. They would not be required in any of the lowrise buildings. Also, the reason WTC 7 had a Firecom system was because it was built much later than the main complex and Firecom was much newer around 87. The only upgrade the main complex got was until after the bombing of 1993. By that time, Firecom was outdated compared to the voice assisted MXL system, which was then intended to succeed the original Pyrotronics alarm. That explains why no reports ever mentioned anything otherwise. *Edit* I found the original video from Evan Fairbanks where the audio was added onto: kzread.info/dash/bejne/oq5qwZqQcaytkpc.html It seems that the original footage did not have any sound, which explains why there were effects added.

The first fire alarm is actually standard across Australia.

There's a video of a few men assisting a firefighter to make sure the building below the site of impact was evacuated (I want to say it was the South Tower) moments before it fell. You can hear the alarm that begins at 1:08 in the background.

The original WTC 7 was a very mysterious building... So much in fact that you likely won't find any interior pictures or footage of it prior to the 9/11 incidents, & only a glimpse of it during the tragedies. Such a shame.

some floors of original WTC 7 and all of WTC 6 were rented by government agencies which may explain why not much was recorded there at the time.

I watched a video of inside WTC 7 on 9/11 and it had this exact alarm. I also listened to NYFD recordings inside the twin towers that day and I could hear the fire alarms as well.

00:05 To 01:08 The Alarm in the picture is a Wheelock 34-24, it's not a speaker it's a mechanical horn 01:09 To 01:42 The Alarm in the picture on the left is a Roshni Sounder, it's not a speaker it's a sounder. The Alarm in the picture on the right is a Simplex 4051 with 4050-80 light plate, it's not a chime it's a mechanical horn

Thanks for the clarification! Goes to show that I had a misunderstanding of the equipment that was described. Curious, do you know what the speaker systems should've looked like? The Wheelock 34-24 I had mistakenly assumed to be the speaker based on the Port Authority WTC evacuation video. It starts by showing the alarm whilst playing the Cerberus whoops. I did not know at the time of making this video that it was an artistic choice that I assumed to be factual.

@@RobvilleVirtualRealisations Hi again, I have seen a few discussions on the speaker strobes that WTC 7 had. it appears that they used modified Wheelock speaker strobes, similar to the E70-2430W. However, either the strobes were disabled, the lobby speakers did not have them, or the camera just didn't pick up the strobes in the video that shows WTC 7 after the south tower collapse. Either way Firecom seemed/seems to like Wheelock speaker strobes (if the assertion of what WTC 7 had is correct) because the new World Trade Center mall also uses Wheelock speaker strobes and was installed by Firecom.

That has to be the most chilling thing I’ve listened to. And to know this what people heard while watching and waiting in fear and terror, praying and hoping for whatever end was coming. It almost gives you the same sense of horror.

the first alarm is the one that haunts me the most, if you watch the full jules naudet tape it's constantly in the background from when the firefighters first arrive to when the south tower falls

I would like to point out that the video in the description being used as evidence for the alarm systems in 4, 5 and 6 *almost certainly* has dubbed audio. It sounds exactly like the audio from the video taken in WTC7. You can even hear the part where the camera man (camera man filming WTC7) is running up the escalator which doesn't match the video at all. you can even see a part of the video where the image skips but the audio of the alarm doesn't

@@DatamasterCorporation Interesting note there. The chime sound does indeed overlap a cut. I'll download the video with LaGanga's WTC 7 video to see if the alarms overlap perfectly. If so I'll remove that note. It could explain why it doesn't make sense that the complex was partially Cerberus and partially Firecom. WTC 7 used Firecom because it was built later and a bit of a standalone entity to the complex. The concourse however was there from the beginning so it would make sense the systems within would match. I appreciate the insight.

@@DatamasterCorporation It turns out you are right. Very well spotted! The sound from Mark LaGanga's video perfectly overlaps the one in the lowrise evacuation video. Aside of the alarm sounds matching perfectly, I was able to distinguish a ringing phone in the background which can be faintly heard in both videos at the exact same time as well. I'll remove the note, and thanks again for pointing that out. *Edit* I found the original video from Evan Fairbanks: kzread.info/dash/bejne/oq5qwZqQcaytkpc.html Turns out the original does not have any sound in it, hence why the uploader of the edited footage has added effects. Shame the uploader doesn't acknowledge this.

I am such a goddamn idiot I was wondering why there wasn’t any alarms after 2001 :(

I think all fire alarms should be voice assisted , I think it gives a clearer message to indicate a real emergency. These alarms are always so haunting to hear especially knowing where and when they were used. Take a moment of silence for those lost.

I saw a video that was like five minutes before the seven building collapsed and they’re saving people and that fire alarm was still blaring that chime kind of sounds like the back rooms

All of these are very very terrifying. I would actually be terrified.

Used to work on these systems. Very familiar sound to me. The effects are better in person with the flashing strobes

these massive buildings are so cool. they’re like a modern car with a bunch of different sounds and chimes and everything is controlled by some “machine room” with electrical components and ecus/computers and stuff like that.

The complex truly was a city within a city. I don't recall that there has ever been a building with more floor space than this. Both before and after 9/11.

Imagine going out in wtc 7 and hearing a bell sound

1:28 I remember hearing that exact sound in a dream where I was in Level “The Metro” in the Backrooms. I remember 2 new files on my phone’s “Files” app appeared in On My iPhone without a file extension and no spaces just snake case and the wiki said that deleting one of them would cause you to get thrown out of the train and into a void and I forgot what deleting the other one did but it was bad. But I heard that exact sound when the Metro stopped at a stop, that sound played in the metro train while it docked to open the doors, while it was totally empty both the train and station. Never saw a single entity or human.

I remember the WTC7 fire alarm by watching a video recorded by some reporter using his TV camera.

This was the last sound many firefighters heard

Building 7’s alarm is bone chilling and nostalgic at the same time. Given that I was born after 9/11 I wonder if it’s standard in the city and I heard it from there?

pretty sure the first alarm was still in use at least at the Greenhouse Cafe, as the audio recording taken by the FBI Agent stationed there when Flight 11 hit has the same one playing, apparently without the voice-over heard in the later one
