Awesome rare deep sounding siren: Old German WW2 siren in ACTION

[@pgrapefruit7033]

Imagine during ww2 as a kid you woke up hearing that and knowing well what that meant

[@Kekzilein]

My dad was a little child in WW2 and was living in Berlin so he heard the Air Raid Sirens quite often. I don't want to imagine how scary that must have been for a child. Those sirens creep me the fuck out.

[@CamouflageFacePaint]

Germans have good air raid sirens.

[@e57michel]

***** of course, no doubt about it ...........

[@CamouflageFacePaint]

e57michel I know. I want to see some of their Electronic Air Raid Siren.... Can you send me one link of it?

[@creepyendy]

thx im from Germany every Sunday they tested them

[@CamouflageFacePaint]

creepyendy Now ours, It depends on a local agency known as Emergency Management Agency (Used to be Civil Defense) They get to choose when they want to test them. It's usually on Sat. We have a crappy Whelen 4004/Vortex R4 (Can't tell which one is. They both look the same)

[@adamczech1461]

+e57michel I wish Americans had sirens like that.

[@orlandof.3220]

this is more creepy than the actual ones.

[@JGripen39]

This gives me the chills..

[@burritomensch1257]

Dang, Germany. Your sirens are almost as scary as the ones here in America...

[@RANDOMLETTERS1111]

Id say its way scarier

[@jacobtompke8677]

What about British air raid sirens? 😮

[@chriswheatley3871]

British have to be the most terrifying I've heard

[@burritomensch1257]

Chris Wheatley Turns out America does. Look up 'Chicago tornado sirens'.

[@ahort]

This sounded... YAY!!!!!!

[@mikey-de1cy]

the way it sounds like. in WW2, that meant do not play around. plus, it kinda gives me the chills since its low.

[@theghosthunter6123]

Justin Bieber is in the town.Evacuate town!!!!!x5

[@neepneep5138]

Haha 😂😂😂😂

[@lashondapope4461]

that was actually funny lmfai

[@Cuenta-ry4bm]

Sounds like my ceilling fan

[@Vyclops]

XDDD

[@DutchGuyMike]

+john hamlet Lol

[@cryxia4449]

+john hamlet LOL

[@ViridusMusic]

HOLY SHIT HAHAHAHAHHAHAHAHA

[@skeletanger]

this tone is so much deeper than a thunderbolt 1000t

[@filippietrzak9900]

Beautiful sound, beautiful siren... :D

[@shorne03]

its a loud cow

[@BandoBeastUrbanExploration]

LMAO

[@nimeris.]

Shorne xox lol

[@Kiyoko504]

I feel bad for any Birds who take up residence in that thing...as for Squirrels well you're natures speed bump so go right on in

[@XibyYT]

Fon't put your Finger in !

[@MarcusToroian]

3 ports. That is just insane. I love it.

[@MegabyteMii]

I think I'd cry if I heard this siren irl.

[@cvic9842]

More scarier then the actual enemy

[@ReddwarfIV]

It's shifting to the otherworld!

[@MKninjas]

as a volunteer firefighter i would love for this to be our house siren

[@artis1723]

Must be crazy back then. Just imagine, waking up from this sound back then in the middle of night in your sleep as a teen. Worst nightmare ever.

[@e57michel]

yes, there are some several descriptions of this scary siren sign: alarm, attack, warning, warnung, air raid signal, wail-tone, etc..

[@audinos4827]

Before WWII, these low-pitched sirens were used for fire calls, while higher-pitched sirens were preserved for civil defence use. Many were combined into a single siren with two motors and two rotors, but after the war, only the high-pitched ones were used.

[@racer927]

Never heard a siren this low before.

[@Beowolf1970ff]

keiner will hoffen das dieses signal je benutz wird,,, aber das ist der sound den ich gesucht hab eine tiefe sound sirene. danke fürs upload wie von allen anderen uploads Thx e57michel mach weiter so

[@NickSilcox3]

i'l love to hear this thing at a distance with an eerie echo

[@rtralph1269]

Sounds like a sick allertor.

[@e57michel]

of course. i own the same siren-type contructed in times of WW2. soon i will show my old deep-tone siren in a video.

[@nauticalpixel]

Wow, that rotor just keeps going...and going...........and going........okay, this is getting annoying........and...going........and going........ oh look I finally see the indivivual blades..........and going........................hey, it stopped. :D

[@slendermanslendy1298]

this reminds me of one of the maps in bf4 that had the sandstorm the siren sounds just like that one

[@TheQueenofMars]

Such a lovely, eerie sound!!!

[@bangersfuzzy]

Diesen Sound kenne ich so noch nicht. Ist aber Cool, hier handelt es sich wohl um eine Tiefton Sirene.

[@matthewjames2015]

How'd you like to hear THAT in the middle of the night in the spring time in Oklahoma?

[@kathetaliansingsrandomstuf6091]

Looking at the inside from the minimum amount of light you can see, it looks like a large fan forcefully hitting the sides of the metal, creating the loud sound.

[@MrChimeratic]

it´s moving the air... every sound consists of moving air and here it´s simply a lot more and a lot faster...

[@wills.5762]

Im no expert, and Im just making an educated guess, but you are close. Its the blades forcing air through the slots at a very high velocity, causing the metal to vibrate, The discs are there to amplify the noise of the vibrations.

[@sirensandstuff5780]

They work like this... Sirens are just giant air horns. What they do is they suck in air using the spinning thing called a chopper. It's like when a gap opens and closes with rushing are which makes a whistle except with sirens it sucks in the air with the chopper and chops the air while the gaps open and close because of the metal on the chopper. The gaps are also called ports. So they suck in air and blow it out through gaps that open and close at a EXTREAMLY rapid rate. This is the best I can explain it but there are other informational videos you can see

[@BlackMasterRoshi]

BBoi00 00 i thought it was called an impeller

[@shiningarmor2838]

If it was not that rapid, it would sound like dun dun dun dun dun dun

[@e57michel]

then you will never ignore this sound. thats possibly good for your life for a long time........

[@spewmister]

that spin down time is amazing, it must be ridiculously free running

[@e57michel]

the rpm´s are the same for all electro-mechanical sirens with an engine of 400 V AC. it is approx. 2800 rpm. but the different sizes of the air ports makes different siren-tones: low tone with 145 Hz has 3 air ports (this siren type like in the video, or L138, S145, S4) high tone with 420 Hz has 9 air ports (e.g. german E57 sirens, Elektror L1, L141) or high tone with 530 Hz has 11 air ports (e.g. Elektror S3,S4, L138)

[@celsos3027]

I don't know why, but this sound give me shivers

[@Director84]

Yes, I once transported an old man in the ambulance who ducked in fear when the air conditioning switched itself off and made a siren-like sound when the ventilator spun out. When I asked him about it, it turned out he had survived the apocalyptic air raid on Pforzheim on February 23rd 1945; his mother and sister were less lucky, and his father never returned from the Russian frontlines. This man knew, what war really means...

[@e57michel]

@Z32spdstr The ball bearings are designed for long life. It is generally very important for electro-mechanical sirens. Sirens have to run reliable in every situation to warn people in case of danger for them around the clock, in any weather condition.

[@luvmypup93]

We have sirens like that close to my home but their mainly used to alert us of tornados

[@dilloncarpenter]

That has to be the deepest siren ever! Nice vid! Wish we had unique ones like this in America nowadays..

[@vertoisful]

Now that's a siren... Instead of the non motorized crap they have now

[@michaelconstantine6581]

Sounds like a Honda civic and a leaf blower having a contest on who sounds the most shittiest

[@e57michel]

@TeachMehDoug ANSWER: it is a simple fire-siren for today! and i don´t know if this siren warned somebody in times about 60 or 70 years ago. But I suspect that this siren has done this job. that is the purpose to hurt the ears of many people, so you will stay alive in war-situations or in case of fire!

[@AwesomeDesertTrains]

MoooooooMOOOOOOOMooooooooMOOOOOOOOO!!!!!!!

[@DieselPowerFinland]

Sounds like a cow. :D

[@e57michel]

@cld458 yes, with two seperate engines: one for the low-tone (like shown in the vid), the 2nd for the high-tone. (look for the vid: Luftschutzsirene Weltkrieg, old german airraid-siren) each engine has the power of 4 kW (total 8 kW)

[@robertgift]

Nice video! Thank you Michel. Years ago I told Federal Signal to offer a Q siren with 1/4 the ports they now have. Peak frequency would be two octaves lower.Lower frequencies travel farther through air and penetrate vehicles better.

[@e57michel]

@Z32spdstr this siren-rotor in the video has the maximum of approx. 2800 RPM. (because of the 400 V 3-phase AC-engine at 50 Hz power frequency and it is a "star connection") i´m sure it could run faster only in a short time with a "delta connection". but the AC-engine wouldn´t survive this!

[@iandutterskateboarding8408]

Want a scary sounding siren? look up FS Modulator in Chicago

[@e57michel]

headache is much better than WW3!

[@e57michel]

@darkhound891 caused by: a well balanced rotor, 1st class bearings, processed by high-quality materials, very accurate manufactured siren.

[@Calling321]

Very Cool siren, I have never seen that looks or sounds like this. It maybe would be worth some money.

[@OkenWS]

There are some folks out there who would hear this today and shiver, or worse, go into a panic state, just from associating the sound with what happened the last time they heard it. It gave me the shivers to think about what the sound is symbolising...

[@e57michel]

@ihaterabbits127 no, you aren´ t! it is the adjustment of my video-camera. nothing more.......

[@maestro300]

Castle Castings siren- This one is what defined WW2 Air raid sirens for me.

[@CoriNovakskeletai]

I don't know why but this fucking terrifies me ;-;

[@madgirl6years]

It terrifies you because its a air raid siren o-o not much to explain

[@ScoCoda]

callmekico The air raid sirens in some of the U.S States are more terrifying.

[@dtimmys]

Lol i used to be freaked of sirens now i love them. This one actually is pretty scary because you dont hear an old ass air raid siren like this that deep. This is provably the only one of its kind. Ive never heard one lower than this one. This is similar to the french sirens. The sound.

[@anyastar8]

Dafuk!! When I played the video I scrolled down right away to check the comments. I was reading through them when suddenly the alarm started. Aaarghh! That scared me.

[@FrankBoothDeLarge]

That's an eerie and awesome alarm sound. I'm probably going to use this alarm sound in the movie I'm working on

[@BlitztheDragon]

That has to be one of the most disturbing man-made sounds I have heard in a LONG time.

[@e57michel]

@lilaj34siren thats a very good news: what was the reason? a tornado or fire? the siren made a good job (for you and for other human life!)

[@Adambomb645]

I never want to see the day when any siren goes on and never turns off.

[@JEANNEBOLEYN]

I get the shivers when I hear this...the sound of approaching death

[@e57michel]

pour a cold beer in your neck, then no more nightmares! schütte dir ein bier in den hals! da hast keine alpträume mehr!

[@elis4085]

If the siren is authentic, then it had a workload around it's early days!

[@e57michel]

@Blaulicht500 das ist auch ein mords apparat vom durchmesser her. die lagerung wird sogar noch extra gefettet mittels vorhandener schmiernippel am sirenenmotor. ist schon eine sehr beeindruckende alte luftschutzsirenen-bauart!

[@e57michel]

well behaved. some youth should take a good example like this!

[@e57michel]

@TheGondorian so nebenbei: die DS977-aufnahmen eurerseits sind ebenso sehr gut gelungen! (diese sirenen-art in aktion fehlt mir auch noch in meiner sammlung! werde irgendwann mal einen angriff starten, solch eine aufnehmen zu können.)

[@e57michel]

@Z32spdstr i´ve forgotten to remark: The ball bearings still get an extra lubrication from a outside grease nipple to increase their life. thats a special feature for this siren-type.

[@Tim.Pierce]

this the sound you would've heard back then when it was imminent that they were gonna drop an A bomb down your pants... jeepers creepers!

[@e57michel]

it is its natural frequency at special rpm´s of the big siren-rotor. then the whole siren begins to shudder or vibrate.

[@CraigBaker96837]

This takes the term "octava bassa" to a whole new level.

[@redoritos1951]

it sounds like my lawnmower

[@UNIX32]

sounds like a Chrysler siren in a tunnel

[@e57michel]

don´t forget: unfortunately also for today, if there is war in some countries.

[@slayer286kill3]

I dont know why, but I found the sound of it winding down to be extremely satisfyling.

[@c2thefuture]

this siren is awesomly epic sounding

[@e57michel]

@cld458 no, the high-part! the low one is activ!

[@747er]

Wow, was ein Sound! Die zaubert ein fettes Grinsen auf mein Gesicht :))

[@Blaulicht500]

Die braucht ja verdammt lange bis zum Entgültigen Stillstand. Scheint wohl sehr leicht zu laufen bzw ein schwerer Rotor zu sein, oder liege ich da falsch?? Dies ist aufjedenfall wieder eine sehr schöne Aufnahme. Vielen Dank fürs Hochladen, Michel. Daumen hoch!!

[@Sleep-is-overrated]

This is what I would imagine Silent Hill would use for their next game...if one comes out that is

[@defysquirrel189]

holly crap that is one cool siren!!!!

[@e57michel]

@HotTop202 the siren-tone gets higher. check your mail for a sound-example!

[@minddevastation508]

Would be more foreboding as a dual-tone siren

[@oOHoodooManOo]

Da hat sich das Warten ja gelohnt ;-) Echt gutes Video.

[@e57michel]

be glad you only hear it ..........

[@VolldampfHarzFilme]

Super Sound!

[@3m_ma]

freakyyyyyy! anyone else get flashbacks of what it would've been like with this around

[@xxraiserofhellxx5910]

+Emma Louise You can't get flashbacks if you weren't there. You're just imagining what it'd be like. The answer is; total chaos and hell if it were for civilians. However, if it was on a military base, they'd be more trained for the situation, and more orderly about it.

[@griffenjames994]

this is the most fucking terrifying thing I've ever heard in my life

[@invictus2633]

I'd probably shit my self when this thing crack up..

[@akosiadam7216]

wow that is scary as fuck

[@readman010]

9/10 of this video is watching german bearings triumph everything

[@kyliechristine2833]

AAAAAHHH!!! Scary :(

[@planetenwanderer5329]

Beautiful Sound!

[@e57michel]

@ohbobsaget22 nonsense to replace a full functionable (but old) siren. and besides it is in Austria.

[@das81]

00:16 "This is your emergency broadcast system, announcing the comensement of the annual purge sanctioned by the US govertment...."

[@e57michel]

@HotTop202 thx. :-)

[@danishown2]

nice that siren has been used many times under WW2:O

[@raysharky3313]

I hear this in my nightmares...

[@usernamenotavalible9032]

Sounds like my neighbors Honda civic

[@cristiandicu7094]

i have "cool wave" on my back when i hear that sound... is scary!

[@e57michel]

@Tblurg94 yes, it is! and in an unbeatable f****** good condition about 70 years! wooww! ;-)
