Earth gives off a relentless hum of countless notes completely imperceptible to the human ear, like a giant, exceptionally quiet symphony, but the origin of this sound remains a mystery.
Now unexpected powerful tunes have been discovered in this hum. These new findings could shed light on the source of this enigma.
The planet emanates a constant rumble far below the limits of human hearing, even when the ground isn't shaking from an earthquake. (It does not cause the ringing in the ear linked with tinnitus.) This sound, first discovered a decade ago, is one that only scientific instruments - seismometers - can detect. Researchers call it Earth's hum.
Investigators suspect this murmur could originate from the churning ocean, or perhaps the roiling atmosphere. To find out more, scientists analyzed readings from an exceptionally quiet Earth-listening research station at the Black Forest Observatory in Germany, with supporting data from Japan and China.
Different types
In the past, the oscillations that researchers found made up this hum were "spheroidal" - they basically involved patches of rock moving up and down, albeit near undetectably.
Now oscillations have been discovered making up the hum that, oddly, are shaped roughly like rings. Imagine, if you will, rumbles that twist in circles in rock across the upper echelons of the planet, almost like dozens of lazy hurricanes.
Scientists had actually expected to find these kinds of oscillations, but these new ring-like waves are surprisingly about as powerful as the spheroidal ones are. The expectation was they would be relatively insignificant.
New thinking
This discovery should force researchers to significantly rethink what causes Earth's hum. While the spheroidal oscillations might be caused by forces squeezing down on the planet - say, pressure from ocean or atmospheric waves - the twisting ring-like phenomena might be caused by forces shearing across the world's surface, from the oceans, atmosphere or possibly even the sun.
Future investigations of this part of the hum will prove challenging, as "this is a very small signal that is hard to measure, and the excitation is probably due to multiple interactions in a complex system," said researcher Rudolf Widmer-Schnidrig, a geoscientist at the University of Stuttgart, Germany.
Still, a better understanding of this sound will shed light on how the land, sea and air all interact, he added.
Researcher Dieter Kurrle and Widmer-Schnidrig detailed their findings March 20 in the journal Geophysical Research Letters.
who knows? it could be series. ;-)

But...but...Earth Worshippers HATE HUMMERS!!!!!...........
I think I just heard it now... or maybe it’s just the bean burritos I had for lunch.
I believe there are places on Earth where people have traditionally said that you can sometimes hear a mysterious hum. I imagine that most of the hum being discussed here is at frequencies which humans cannot hear — but it would appear that the modulation sometimes rises up into our range.
True, but we must encourage everyone to remain clam.
I’ve heard of Cosmic background noise, this one has me hmmm’ing tho.., could it be an excited electromagnetic field phenomenon?
If anyone has some related sound links for this, please post.
Maybe this noise is what animals hear and then move out of dangers way when earthquakes are imminent.......
Hmmmmmmmmm......Hmmmmmmmm.....Hmmmmmmm
Running, fleeing,OUT of here! :)

must be a wavelength phase thing,, the right spot at the right time.. there are some spots that are reputed to be focal points for energy flux fields on Earth.
I wonder if its related to tooth fillings or jewelry.. Gold and amalgram, heightened solar activity, hmmm..
I’ll have to dig a little deeper on this one.. :-)
And why does the earth hum?
It don’t know the words.
Did they ever think to check for the souce in Tibet? Ommmmmm
Is it humming “Love me like a rock”?
thanks for posting the article.
Hear the hum?
Well, same thing. Larger scale, extremely lower frequency.
Jillions of units of energy go in at the poles, the ‘magnetic’ poles are the brushes.
The Earth supposedly has a fluidic,semi-metallic outer core (winding), and a dense, solid, inner core (armature shaft)
The horsey goes round and round.

Hmmmm! I always assumed that was the sound of the air going through one of Al Gores ears and out the other one.

I understand that the humming sounds eerily similar to the Doctor Who theme music which drove the Master mad . . .
mystery solved ,, or maybe not..
it’s pounding waves on the ocean..

I don’t know, some folks are still not so sure..
I’d put my money on the Mole People
“Maybe this noise is what animals hear and then move out of dangers way when earthquakes are imminent.......”
I suspect animals hear a peak, or change in frequency of the noise, with a sudden loss of the signal, just at the onset of the earthquake.

Love me like Barack.
WOW. Could the moonbats of Sedona be right about their vortexes ?
“Taos Hum”
Thank you maggief.
It’s the sound of our forefathers spinning in their graves.
BUSHES FAULT.........
>>>Maybe this noise is what animals hear and then move out of dangers way when earthquakes are imminent.....
Quite an interesting thought.
The entire planet is a Helmholtz sphere with its characteristic resonant frequency of about 8 Hz.
or maybe “2001”....
Chillin’... waiting for you to put me in, Coach.
“Gold and amalgram, heightened solar activity, hmmm..”
Heightened solar activity causes not only more growth, but better growth.
Plants are ‘healthier’ during heightened solar activity.
People, for instance, are ‘smarter’, during heightened solar activity.
Which is why it seems the world around us has gone insane lately. The Race for President, for example.
I have noticed that many, many posters keep making the same mistake while entering a post. They leave out words, or use IS where IN should be, etc.
The SUN is vewwwy quiet right now (which we all know), and I think our brains need the GAMMA RAYS as stimulus.
Maybe that's where the word rock came from to start with....
And of course...that leads to "Rock and Roll"....which leads to....
The problem is....If we can't hear it....Does it exist??
It's probably some old refrigerator....Or....The factory that makes ribbons from all the "lost socks".
Or maybe....It's just "A HUMMER"...that someone left running.
“Where were you when I laid the earth’s foundation. . .”

>>It’s the sound of our forefathers spinning in their graves.
LOL
I wonder if their spins change speed according to their dismay?
How fast do they spin when private property is “taken”? Faster or slower than when the gun grabbers crawl out of their holes?
Things that make you go, “Hmmm ...”
“The entire planet is a Helmholtz sphere with its characteristic resonant frequency of about 8 Hz.”
And it’s children, (us), resonate at that very same frequency.
Food, (or vibration) for thought.

I kinda figured they were just part of the Earth itself. ;') Thanks NormsRevenge, this is pretty fascinating. I'd post a link to J. Marvin Herndon, but I've been foolin' around online too much today. :') Unlike most days (yeah, right).

I knew it...it is Rove's weather machine. Therefore it follows that it must be Bush's fault!
I just went into a dark, quiet closet to listen for it...I sat quietly for almost an hour...I began hearing an extremely soft tune...it was hauntingly familiar...
"I'd like to teach the world to sing, in perfect harmony..."
