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.

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).

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’ve heard it postulated from time to time that these low-frequency noises are what homing pigeons use to find their way around.

I wonder if it’s possible for the scientists to record the sounds some way and speed them up so that we can hear them— make a symphony kind of like that guy did with “And God Created Whales”

Let's do a normal mode analysis of the Earth.

Complicating factors:

oblate ellipsoid;

core / mantle / crust;

atmosphere / oceans;

Cheers!

“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,
