this siren isnt meant to warn the public its meant to scare away the tornado

*“Sir, how should we warn the general public of imminent danger?”* *“I think howling sounds of hell would do nicely”*

Ever since Chicago started using this siren, they have never had a single tornado since

The alternating wail is easily the scariest siren out there. Just listening to it sends chills down my spine.

Scared by the tornado: *nope* Scared by the sirens: *yes*

"The only siren designed to actually make tornadoes uncomfortable and leave"

imagine being in the woods and hearing this 💀💀

I can understand how experiencing this scenario can be freaky and traumatizing. My area has actually been hit by bad tornadoes but our sirens don't sound like this....

if this starts playing, the only reason the tornado would come by is to rescue people from this terrifying fucking siren

That is not what a tornado siren sounds like, That is what an ice cream truck from hell sounds like

this is a modulator/DSA siren, its an alternating wail. only some sirens can do this, specifically sirens with SPEAKERS. sadly, most sirens in chicago are electromechanical, so they make the noise with a rapidly spinning chopper. alternating wails are used by sirens with speakers for water related disasters, such as the one shown here, or hurricanes (which is extremely unlikely in chicago, its only happened 17 times)

2010: Freaky tornado siren 2020: S I R E N H E A D

This is why tornados don't come to Chicago.

this is some Silent Hill material going on

This has got to be the most terrifying noise I’ve ever heard

Therapist: How would you describe your nightmare? Me: playing this video

The fact that this happened during a fog makes it more terrifying.

Tornado: *Is about to pass through Chicago* Tornado: *Car lock noises*

I remember visiting Chicago to see my aunt and uncle and hearing this on the 2nd day we were there. It was cloudy, cold, and the winds were blowing pretty high. The sirens went off due to a Tornado Watch but thankfully nothing happened.

Finally I found the siren head siren sound, for me this is is honestly one of the most scariest sounds I’ve ever heard

Tornado - I sleep This siren - REAL SHIT

Man Chicago you know how to scare away the tornado and all of the city.

Most people say that this siren is broken and made a creepy sound. But it's probably an alternate wail siren making it's normal sound.

We had the same model where I grew up, twenty miles east of Pittsburgh. They activated it for multi-alarm fires instead of tornados, most of the time. It echoed through the valleys and sounded very loud, even through we lived at least six miles from the fire station. It was beyond creepy to hear more and more fire engines, then they all cut off and we're left with this distorted banshee wail and nothing else.

Literally everyone: "terrified screaming" The Demons in hell: "oh boy looks like the icecream truck is here!"

*"Sir, we need to warn people about the incoming tornado without causing panic, what should we do?"* *"Play this."*

It’s just a normal day in Chicago until the siren starts walking

It’s weird, I drive by this place like everyday and never knew this is where it was recorded. The more you know

Tornado: welp. It's time to hit the city! Siren: *LET ME SING YOU A SONG OF MY PEOPLE* tornado: nope. *turns around*

That siren isn’t to warn people of the tornado, it’s for scaring it away.

Just imagine this while in the middle of walking back to you're house from wherever 😂❤❤

I'm getting chills just listening to it

chicago tornado siren: exists fact channels: sCaRy uNeXpLainEd sOunD

The funny part was that the video was shot during a foggy day. Welcome to Silent Hill, everyone.

A lot of people think that siren is broken. But that's actually a tone called "alternate wail" just search that up.

The Tornado after hearing this: understandable have a nice day

tornado: Who are you?!? tornado siren: I'm you but scarier

Its sounds like an ice cream truck from hell

Even the dogs, said nope - no barking for me today, call me when there's fire truck 2 miles away.

Chicago people: mmmm just a regular siren other people: wait….. IS THAT SIREN HEAD… AHHHHHHSH

This siren is successful in making sure no one dies from the tornado Because they die from a heart attack instead

Chicago Tornado Siren: *makes demonic ice cream truck sounds* Tornado: Ight imma head out

This Is the original sound of siren head

When you hear this siren,it feels like the end of the life,but when you hear it while this is paused, *its actually the end of the life*

This is actually terrifying

Demon : I am the most evil thing in this world Chicago Siren : HOLD MY BEER

come back to this video every few years

this ran shivers down my spine

The siren is going through puberty

Everybody gangster till the siren starts walking

In case yall are wondering, the siren is a modulater 2008 alternate wail

Imagine hearing this and looking out your window and in the fog you see a tall silhouette of a creature coming closer😰

Tornado: imma attack Chicago Siren: *goes off* Tornado: ight imma head out

Siren - *turns on* *Tornado rate drops to 0%*

Chicago has the creepiest tornado sirens I've every heard.

2010: this is a terrifying siren 2023: haha siren head go wee woo

Siren developer: so how many hell sounds do you want? Chicago: *yes*

Id be more scared of the siren then the tornado...

In my dream, there was a thunderstorm, a tornado and a tsunami all at the same time☠️☠️☠️ Thankfully it was just a dream😊

This is where siren head's sound originated from

I lived in Chicago basically my whole life, and when I was a little kid I heard this for the first time and didn't sleep for days. Thanks Chicago, love you ♡

9 years ago: creepy tornado siren 2020: SIREN HEAD

This is the sound that makes tornados run away from the Chicago city, by making them afraid by its sound.

Bro summoned a whole gosh dang fandom 💀👍

Within all 8 years I lived in Chicago, I have never heard this until one day I woke up to make coffee and my 18 year old self started panicking because I thought I was still asleep or possibly dead or maybe even schizophrenic. It was definitely disturbing to sit and drink my coffee in that sound that just surrounded me. Good times. Thank you Chicago, never a dull moment😬

Plot twist: This isn't a warning, it is Siren Head having an asthma attack

I live in Chicago, the sirens do not sound like this, it has been altered to sound creepier, it is a siren , and a SIGNAL to get to safety.

Every 9yo listening to this: ✨ OmG ItS SiReN HeAd ✨

Void memes: *Its free real estate*

I lived here and this siren scared the crap outta me

I think this would be enough to get the citizens inside.

If I heard this I'd assume the end of the world has arrived. These fucking things would cause panic

If nope had a sound

The Trevor Henderson Fans: S I R E N H E A D Normal People: This Is a Scary Siren!

Nah but the fact that sirenhead/this sound are already nostalgic is insane

All the city's ice cream trucks died at the same time.

Tornado : Here I come! Siren : *WhEewHoOWhEewHoOWhEewHoOWhEewHoOWhEewHoO* Tornado *screams*

2023: just the chicago tornado siren 2018 people: 😄😃😀🙂😐💀

Tornado sirens be like: WEWOWEWOWEWOWEWO Me: still terrified for some reason…

Me: *suddenly hears this* Also me, who lives in a forest: Haha im in danger

Tornado:I have no fear *Chicago siren plays Tornado:But that thing it scares me

Finally I dont see anyone commenting "oH mY gOd iT iS sIrEn hEaD!!!"

Tornado: IM GONNA INVADE CHICAGO Siren: *playing* Tornado: I think I wanna go home now. Bye, have a great time 😊

Siren: **exists** Tornado: *UNDERSTANDBLE HAVE A GREAT DAY*

I’ve lived in Chicago for about 12 years now, and I remember hearing the sirens and thinking something paranormal was happening!

Imagine you finish the video and the sounds are still playing💀

is this eows 1212 alternate wail or modulator alternate wail?

Plot twist: This isn't to warn the citizens, it's to scare the tornadoes away.

The Tornado Siren: **exists** Siren Head: _You will be a great soldier._

I find it mind calming, i listen to it on loop, i even have it in my playlist so i love it 😁

Don’t worry, my uncle is from Chicago. He’s assured me the tornado sirens are supposed to work like that! (I’d send proof, but I can’t exactly send images on KZfaq, and that message was a year ago, lol)

The scariest part is that some people can’t find good shelter in time, so this noise was the last thing they heard before they died...

This is more like some apocalypse alarm like :"We're sorry we couldn't save you." Imagine that.

Me hearing this in chicago 😐 Me hearing this as the ice cream truck goes down the street💀

'alternate wail' signal.

A tornado will be scared of that tornado siren

that's a terrifing sound

Tornado: "Watch out Chicago, I'm coming!" Siren: "Nothing beats siren head!" Tornado: "Err, I'll come back later. Yeah. Another time for me..."

Wasn’t there a monster?

Fucking hell this is terrifying
