Earth's Hum Sounds More Mysterious Than Ever
LiveScience.com on Yahoo ^ | 4/16/08 | Charles Q. Choi

Posted on 04/17/2008 11:07:31 AM PDT by NormsRevenge

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.

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.

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.

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.. :-)

About 20 years ago, near Taos, NM, I was our walking with a group and we heard weird hums. We went back the next day and heard it again. Definately something weird.

thanks for posting the article.


My dumbass, uninformed, misguided, opinion.


Turn on some electric motor.
Put your ear next to it.

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.

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.

“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.

The earth rocks....Who knew...

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.

How fast do they spin when private property is “taken”? Faster or slower than when the gun grabbers crawl out of their holes?

“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.

Gosh, I had no idea that the oceans and atmosphere could "push down". 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).
