I am giving you a star and flag for doing what you did, recording and posting the sound.

It is kind of faint, but can be heard in the background. I am guessing that you have heard planes in the air before and that you believe that this noise is different.

S&F

This is becoming all too common...

I have now taken a deeper interest in this.

Here is a copy/paste from a response on a similar thread today that I posted....

(People have started to compare the sound to trumpets as well as heavy machinery. But the 'trumpets' responses have increased...Dbriefed here on ATS quoted several biblical scriptures, describing the 7 seals, the horses, with beasts, angels and trumpets....and here was my response )

As a strong believer in Extraterrestrial intelligent life, and the Ancient Alien theory, here is my 'take' on what those scriptures mean-

Horse: vessel for transportation, as referred to in 'chariot of fire'

The seal being broken: A door opening, as in a door on a vessel

Horns: the sound that the 'space vessel' makes

Angels: aliens ('messengers', as in clerk-level....assistants)

God(s): aliens ( leader, commander, specialist)

Rapture: mothership arrival for mass abduction

I've been hearing this noise near Powder Springs for MONTHS now (maybe a year), usually at 3 am-4 am and have reported it more than once in others' threads on ATS, but I've never seen anyone mention the Atlanta area till now.

It varies in intensity and usually I'm too big a chicken to go outside and the few times that I did try to record it, I got nothing that sounded like anything I was hearing. It sounds way different to the human ear, and it ebbs and flows...almost vacillates? You think it's over and it restarts maybe with a bit of a different pitch. I've pretty much resigned myself to the nut bin.

Thanks for recording and posting this, Vasa Croe....you may have inspired me to try again.

P.S. I haven't heard anything tonight, but now I'm listening...will let you know.

That sounds like the hum of a C-130 gunship, I live near an Air Base, and that is the sound I hear while they are about to taxi onto the runway for take off, sometimes they can idle there for a long time.

unless I just don't hear the other part?
S&F for others to add input.

Thanks for posting. I have yet to hear anything different than weather or planes (live by an airport about 20 miles or so, probably less as the crow flies though).

Now I do feel the house vibrating a lot, especially when I go to bed. At first I thought it was just my body relaxing, but that just doesn't happen for several hours almost nightly. My tempur pedic bed absorbs a lot- their is only 1 thing I miss springy beds for, but not having a bad back was well worth the cost of the bed plus my loss of a we bit o the rough n tumble.

I dont know but from ball ground ga it sounds as if some one left a fan on or im missing something

I grew up here and Dobbins is nearby. I have heard many many prop planes on the runway, overhead, and been to numerous airshows. The only thing I can think of that this sound compares to is the hum of a squadron of large prop planes above the cloud cover in the air like what you hear/see in the old WW movies with all the paratroopers about to jump out. Very low humming that fluctuates in intensity. Been going on for a while now. About to go back outside and check for it again.

Thanks for the replies and if I can I will get another recording.

I have to say, I'm really pleased to see so many long standing ATS members reporting personal accounts of hearing these strange noises. Makes me feel much better about the two events I heard.

What the heck is going on?

Sound is still going on unfortunately there is too much background noise right now on the streets nearby to get a good recording of the low hum. My fiancee even called me outside at one point to tell me to listen because it had begun to fluctuate louder then softer again. Right now it is still just a very low hum.

Headed to bed....will try again tomorrow.
