Ufo, Weird unidentified sound, Marietta, GA

[goinghard101]

Alien cops!! Im just gunna repeat wat someone else said cause thats funny as shit

[BrianLuper]

Sounds like a Lockheed test/drill. I lived in the same area from 1990-96. But, I did see a few things in the sky with a telescope during that time around Georgia.

[sweiland75]

so what did it turn out to be?

[sesshy211]

i did some reasearch on your town area on google maps and i think there is a reason for the sounds due the air force base but i found it funny that one of the streets were named Roswell

[timpedersen]

@sesshy211 there's a whole city named roswell, ga :)

[enriquemartineziii2]

those are sirens some crap 2 thosand

[jfcrock37]

Lockhead airfoce base alert test

[g1pn0z]

ITs ALL HAARP 

[PootStip]

Its a power station, dude. The building I work in is huge, like acres, and has its own. Sounds exactly the same, but they do it in the middle of the day. Don't know what they're doing, but it's a power station.

[kingiescastel]

turn the vacuum cleaner of dear? i can hear a strange sound. oops its gone quiet

[abyess9]

Hahaha you thought you was gonna have a similar video like the one in Florida but unlike their "REAL"mysterious sound...Yours was just a ALARM JACKASS!!!LMFAO

[acesoftrul3z]

Fuckin alien cops

[IndigoCat17]

What is the constant humming?

Sounds like a vaccum but the

whinning and wooping is a car alarm!!

[BassettofStarCommand]

that is the strangest sound i ever heard the siren like sound that is. I have no idea what that could of been. The only thing i have been around that sounded anything close to that was a Osprey military er plane helicopter type thing.

[Ashrieni1]

Its coming from one of those houses dude.. you can see a faint line on the left side on top of that one house with the light if you look at it carefully right when you say "can you hear that?" in the beginning. Someone is being abducted..

[scupking]

Any factories near by? That is loud...

[realisrealizerealies]

Thought it was just a vacuum at first, then I heard IT!! Gave me a chill!! Owl or Could it have been someone blowing into a Kontch after burnin' midnight oil!

[Domino587fly]

thumbs up fo marietta!

[dancaldwell230]

its blue beam a holographic sound as well as holorams you can see, its being tested for the false alien invasion and then the coming of christ in the sky for all to see. yep if ya dont believe me just google project blue-beam its a real thing. so aside from the noise it shouldnt hurt you unless the frequency is set to shake you apart or drive you mad and other effects in between, peace

[colyo222]

No way! I was hearing that humming sound up in Michigan! Not with the pulsing tone, though. Just the humming sound. It's always in the middle of the night and it got on my nerves and I couldn't sleep! It was so annoying!!!!!!!!!!!!!!!!! I could not figure out where it was coming from, though.

[elite055]

dude thats weird sounding.

[jnf1222]

i remember hearing this. I live near Bells Ferry and Barrett Pkwy. I found out later that it was the civil defense alarm from town center mall, it was malfunctioning. It was pretty damn freaky at the time....

[edgeofsins]

When cars speed up really really fast they sound like that. And I mean cars with good engines. But it sounds a little less rough so it could be something else.

[tiger7577]

I've only lived here in Cobb County since August, and I have heard the test tone in ALERT mode. Never heard any other. I live in the neighborhood at the corner of the fairgrounds, and we have a Whelen here.

[murrfarms]

Wow, we had a Whelen 4004 do that same thing here in Perry, GA. It kept going absolutely nuts until it finally blew an amp and all 4 drivers. From what I found out, the voltage regulator in the timer shorted out and caused the timer to keep reactivating the siren randomly until it finally pretty much self destructed.

[soccerdude7330]

Haha, looks like you were awoken by a malfunctioning tornado siren!

It sounds like a Whelen 2800/2900 series.

[Leafblower29]

It's a Whelen 2910

[goblue1122]

Cobb County did apologize for the inconvenience.The siren first went off 930ish the night before and sounded for several minutes (10-15).It started in ATTACK mode. Since I know the different bursts a warning siren sounds, it did have me concerned at first (there was no testing and absolutely no weather issues).It went off approx every 2 hours after that first sounding and stopped early morning. CEMA did say it was a malfunction. I couldn't sleep either, but I did know what was going on.

[nicolaj0154]

that sounds like a whelen siren.

[skullcrusher301]

If it is human the testers must be rude enough to sound in at 5 AM

[crunkeyjimmy5427]

Thats weird. We have the exact same sirens here and they sound pretty much like this. They do that woop sound, echo a whole lot, then do it again. You wouldn't be ablt to tell one woop from another. I think that's what is happening.

[videogamer24385]

The SIRENS you are hearing are whelen 2800's for either an early morning tornado drill or for a tornado warning.

[jsncrso]

If you drive around you can see the sirens yourself, they look like giant speakers on a telephone pole

[coyoteunknown]

Agreed with the couple of others, those are Whelen omnidirectional mass notification warning sirens. They're sounding the "Alert" signal, but for whatever reason, they keep playing the "wind-up" that comes on before any signal randomly throughout the activation. They probably malfunctioned.

[mattdean1003]

What you are actually hearing are Whelen tornado warning sirens. Marietta has quite a few of them, The "boooop" sound of it whooping up gives it away.

[kodykile]

did you notice the changing colors in the sky? there were abunch of different ones, blue,red,green.

[waxelastik]

Yea, when I first started filming I noticed something in the sky fly by really fast and then stopped and hovered above me. You will notice when I pan the camera to the left. I zoomed in and it was just hovering and blinking all of those colors. What was weird is when it flew away it made that crazy siren sound. Im still wondering what happened that morning

[waxelastik]

Did you all notice the constant humming sound as well?? That went on for about 30 mins and the weird inconsistant siren noise followed.

[Brak710]

That constant humming is a siren doing a solid tone. It sounds like that until it receives an "off" signal.

[waxelastik]

no it didnt wake up anyone else. thats whats weird. i had been suffuring from insomnia so i was already up. it only woke up my girlfriend. notice when i walked around the apartment no one else was out side. weirdist sound ive ever heard in my life. i dont think its a siren because the sound is not contant. roo roo roo for ex. it very spratic.

[cauberallies]

It is most definitely a siren. More than likely a malfunctioning electronic siren. A few people that have commented, myself included, are outdoor warning siren enthusiasts. Most of us can tell exactly what a siren is just by the sound, so we aren't just making assumptions.

[pistonfire182]

Arn't there any regulations for siren testing, in terms of what times they can test, i know this particular siren seems to be malfunctioning but lets say it wasent then arn't they breaking regulations of some sort?

[mercanaries3]

@waxelastik

thats a siren

[ViperAleks]

@mercanaries3 Yeah, it sounds like alarm sound.

[mercanaries3]

@ViperAleks

lol siren test, it echoed

[Voidka]

Are you in a valley? That weird noise sounds like its echoing. If it isn't echoing, then something further out is mimicing the original sound giving the illusion of an echo.

It sounds almost like a slow motion recording of a cop car turning on its siren for a split second.

I've never heard a noise like that before.

[AgentEnigma]

This is just a wild stab in the dark but I think they might be warning sirens.

[Piostfelix]

awesome ... o.O

[cindiloohoo]

Strange. Did it wake up anyone else in your house or neighborhood?
