Earth's Hum Sounds More Mysterious Than Ever »
Posted By not2needy 1 year, 2 months ago in Science & TechnologyEarth 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.

FTA:
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.
Who knew the earth had a hum!? I wonder if it's caused by the speed at which the earth revolves etc.

n2n it could be caused by friction as the earth rotates there is a bit of drag between the atmosphere and the earth. Theres a meterologist term for it...can't recall the name off hand.
Coriolis effect or something like that.

great article. It could also be from the differential speed of rotation between the 10 mile upper crust and the core.

No i didn't know the sun had a ring! I guess i'm not too old to learn, only problem is, it's more exciting to learn at my age now than it was when i SHOULD have been learning this stuff.
uhmm. Wait.. I don't think they even knew this stuff back then!

"Only the sun knows what we really need to know,
Only the sun knows the secret,
That more than human can we be, that humans truly locked, in this planetary circle......."
(Paul Kantner, in his hijacked starship, c1970. They don't write music like that any more.)

Ever heard a pulsar? How about the leonid meteor shower? The universe is a giant orchestra with every object, every particle giving off a vibration. Even us.

interesting asiide:
J.R.R. Tolkien wrote a book called the "Silmarillion" which describes the creation and history of his fiction world, "middle earth"
during the creation myth section, he describes a creator god, Illuvitar, first creating lesser Gods (angels), the Vanir, and together they cause all of creation and all of time to exist by singing in chorus. Each improvising around illuvitar. the stories tolkien then tells in his books about middle earth are supposed to be the stories written in those songs.
interesting if your in to fiction

Except for Melkor whose dissonant melodies, all brass trumpets and shouts which tried to down out the melody of the One only to be incorporated into it, were in opposition to Illuvitar.
I read the Hobbit first and then the Silmarillion before I read the rest of the Lord of the Rings. Best way to do it in my opinion.

Not much different from a lot of the Ancient Near East texts and creation myths, not to mention the Judeo-Christian version where it's the 'word' of God, God's breath and the wind of God creating.. Lots of angels around then ;)

Wonder how that could be found, Mutainia?
The technology in those probes is incredible, also the tracking equipment used on earth. I've read that strange noises supposedly picked up from deep space have actually turned out to be molecules knocking together in the hardware used for detecting them!

I suppose they've ruled out a resonance from the magnetic field or the multitude of radio waves and frequencies that have developed over the years that permeate the planet.
Could it be Tennessee Ernie Ford from the grave?

Actually, I have heard of this for quite awhile now.....I have seen reports of people hearing a "hum" continuously while other people around them don't hear a thing. Weird and unexplained is what they said. Somewhere near a place called Taos I believe. Interesting stuff.

perhaps the space aliens at area 51 are attempting to contact their home planet by redirecting their ships communication area into the earth's core. the EM field being generated by the spinning magma in the middle of all the iron is creating a wave field that their signal is riding like a ship without a rudder. so it is spinning about in these cycles before heading out into space.
soon the Vogans will come for their lost citizens. perhaps 2012.

or maybe the turtle on whose back our plate shaped planet rests has begun to awake.

or maybe the mice who had the earth built as a giant supercomputer to determine what the question was to the answer 42 now know and are done with us and that sound is the machine breaking down as they no longer are maintaining it.

I wonder if it is an S.O.S......I wonder if the sound has changed over the last 100 years of human abuse...I wonder a lot with my bird brain that at times if feels over loaded.

It was mentioned that the sound can't be heard by humans but I sort of question that, When my wife and I sit out on our deck and she says how she enjoys the silence I wonder what she is talking about. For the last twenty years or so I hear a hum all the time and I have had my hearing checked several times and they say that there is nothing wrong. One old guy suggested to me that I do to much thinking and my brain has run short on lubrication some days I have to agree with him.
Interesting artical.

Sounds in the ears (tinnitus) can have many aspects, cr57. You can hook up to a machine which allows you to create electronically the exact same sound you seem to be "hearing" in your head. Specialists can then "read" the sound via a detailed printout of the frequency/pitch/decibels etc.
As a chronic tinititus "experiencer" I have this check done regularly, and find that the noise has been constant for years, even though, to me, it has been decreasing in intensity.
The earth's hum is clearly not something just in our collective heads. It's out of our heads (hey, that sounds pretty good!)

Interesting article. What they're describing sounds like it could be harmonics of resonant frequencies. All these vibrations are running back and forth through the earth. Some will interact in which wave peaks will cancel, or re-enforce, depending on phase. These frequency interactions can form the ring phenomena that they described. Most of us have seen where waves seem to stand still in vibrating water filled containers., and take on the shape of the container, or rings.
Those waves are resonating at a particular frequency. Some of these harmonics would also allow for uneven distribution of some of this energy in the earth.
