Awesome rare deep sounding siren: Old German WW2 siren in ACTION
Вставка
- Опубліковано 5 жов 2024
- Now it is time to present you a further interesting close up siren video of an old german "Elektror-siren" from WW2-times still in function. Location is in Austria. (here you can see/hear only the low-tone unit with big 3 ports!). And so it has a very deep siren-sound and this is a curious and scary thing when it runs. Sirentone-frequency is at 145 Hz!
The test-signal is called "alarm" (only available in Austria) and it has the purpose to warn the population in case of dangers like e.g. chemical accidents. Of course this old siren is still in function to call the firefighters in case of fire.

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.
Imagine during ww2 as a kid you woke up hearing that and knowing well what that meant
Germans have good air raid sirens.
***** of course, no doubt about it ...........
e57michel I know. I want to see some of their Electronic Air Raid Siren.... Can you send me one link of it?
thx im from Germany every Sunday they tested them
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)
+e57michel I wish Americans had sirens like that.
Dang, Germany. Your sirens are almost as scary as the ones here in America...
Id say its way scarier
What about British air raid sirens? 😮
British have to be the most terrifying I've heard
Chris Wheatley Turns out America does. Look up 'Chicago tornado sirens'.
This sounded... YAY!!!!!!
This gives me the chills..
this is more creepy than the actual ones.
the way it sounds like. in WW2, that meant do not play around. plus, it kinda gives me the chills since its low.
this tone is so much deeper than a thunderbolt 1000t
its a loud cow
LMAO
Shorne xox lol
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.
3 ports. That is just insane. I love it.
Sounds like my ceilling fan
XDDD
+john hamlet Lol
+john hamlet I think I hear your ceiling fan when my siren sounds.
+john hamlet LOL
HOLY SHIT HAHAHAHAHHAHAHAHA
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
Fon't put your Finger in !
I think I'd cry if I heard this siren irl.
Beautiful sound, beautiful siren... :D
More scarier then the actual enemy
Sounds like a sick allertor.
Justin Bieber is in the town.Evacuate town!!!!!x5
Haha 😂😂😂😂
that was actually funny lmfai
as a volunteer firefighter i would love for this to be our house siren
It's shifting to the otherworld!
yes, there are some several descriptions of this scary siren sign: alarm, attack, warning, warnung, air raid signal, wail-tone, etc..
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.
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.
Never heard a siren this low before.
this reminds me of one of the maps in bf4 that had the sandstorm the siren sounds just like that one
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
How'd you like to hear THAT in the middle of the night in the spring time in Oklahoma?
Diesen Sound kenne ich so noch nicht. Ist aber Cool, hier handelt es sich wohl um eine Tiefton Sirene.
i'l love to hear this thing at a distance with an eerie echo
We have sirens like that close to my home but their mainly used to alert us of tornados
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
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.
it´s moving the air... every sound consists of moving air and here it´s simply a lot more and a lot faster...
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.
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
BBoi00 00
i thought it was called an impeller
If it was not that rapid, it would sound like dun dun dun dun dun dun
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)
that spin down time is amazing, it must be ridiculously free running
then you will never ignore this sound. thats possibly good for your life for a long time........
Sounds like a Honda civic and a leaf blower having a contest on who sounds the most shittiest
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...
MoooooooMOOOOOOOMooooooooMOOOOOOOOO!!!!!!!
Sounds like a cow. :D
Want a scary sounding siren? look up FS Modulator in Chicago
Such a lovely, eerie sound!!!
I don't know why, but this sound give me shivers
What a nightmarish sound. It could be an anthem of the hell.
@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!
@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!)
@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)
@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.
pour a cold beer in your neck, then no more nightmares!
schütte dir ein bier in den hals! da hast keine alpträume mehr!
AAAAAHHH!!! Scary :(
That has to be the deepest siren ever! Nice vid! Wish we had unique ones like this in America nowadays..
@ohbobsaget22
nonsense to replace a full functionable (but old) siren. and besides it is in Austria.
Castle Castings siren- This one is what defined WW2 Air raid sirens for me.
I get the shivers when I hear this...the sound of approaching death
I never want to see the day when any siren goes on and never turns off.
Would be more foreboding as a dual-tone siren
That has to be one of the most disturbing man-made sounds I have heard in a LONG time.
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.
@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!
Very Cool siren, I have never seen that looks or sounds like this. It maybe would be worth some money.
Now that's a siren... Instead of the non motorized crap they have now
@ihaterabbits127
no, you aren´ t! it is the adjustment of my video-camera. nothing more.......
@darkhound891
caused by: a well balanced rotor, 1st class bearings, processed by high-quality materials, very accurate manufactured siren.
@cld458
no, the high-part! the low one is activ!
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...
don´t forget: unfortunately also for today, if there is war in some countries.
I dont know why, but I found the sound of it winding down to be extremely satisfyling.
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.
If the siren is authentic, then it had a workload around it's early days!
be glad you only hear it ..........
That's an eerie and awesome alarm sound. I'm probably going to use this alarm sound in the movie I'm working on
well behaved. some youth should take a good example like this!
This takes the term "octava bassa" to a whole new level.
it is its natural frequency at special rpm´s of the big siren-rotor. then the whole siren begins to shudder or vibrate.
I hear this in my nightmares...
@Director84
so pump up the volume........
this siren is awesomly epic sounding
@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!
That siren sure
Sound like old
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!
sounds like a Chrysler siren in a tunnel
holly crap that is one cool siren!!!!
Watch how long that thing rotates! Someone took good care of that siren!
headache is much better than WW3!
This is what I would imagine Silent Hill would use for their next game...if one comes out that is
@HotTop202
the siren-tone gets higher. check your mail for a sound-example!
i have "cool wave" on my back when i hear that sound... is scary!
Originaly it is a two "sounds" siren. You can see that on the video. Low and high turbine. The low one is missing.
freakyyyyyy! anyone else get flashbacks of what it would've been like with this around
+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.
@Blazeheart114 The creepy thing about that is... EVERY city/town has one of those sirens & they're all operational.
@HotTop202
thx. :-)
i´m sleeping at midnight.....
@TheFilmkoenig
der rotor: er erzeugt mit hoher drehzahl (ca.2800 U/min) in zusammenwirken mit dem stator den typischen lauten sirenenton einer elektro-mechanischen sirene. natürlich spielt die luft in der umgebung vertreten die schlüsselrolle (ohne luft würde es auch keinen ton geben): sie wird durch den schaufelrad-ähnlichen rotor angesaugt (hier von oben) und seitlich durch die vorhandenen stator-ports herausgepresst. das sirenendach strahlt den ton nach unten ab. mal grob erklärt! ;-)
sounds kinda like a huge fan
Sounds like my moms leaf blower on full power with a hint of an echo to it lol
nice that siren has been used many times under WW2:O
this is the most fucking terrifying thing I've ever heard in my life
@Tblurg94
yes, it is! and in an unbeatable f****** good condition about 70 years! wooww! ;-)
@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.)
that is annoyingly awesome!
I'd probably shit my self when this thing crack up..
"alarm" sounds like "attack" and nice siren too
