For the first time, it has been reported that the Earth makes a strange humming sound on the ocean floor, which has been reported in some zones in Antarctica and Algeria. However, researchers consider they can observe it all around the globe. The American Geophysical Union explained a new study of the earth vibrating on the floor of the Indian Ocean.
An investigator stated that these vibrations, generally called the “hum of the earth,” sound like the static on an old TV but are reduced down 10,000 times. This doesn’t enable some animals to hear it. Though no earthquake takes place on our planet, our earth is continuously moving. The air blows, the water flows, the ground collapses, the temperature changes, and so it goes. Investigators believe some of these movements make the agonizing noise, but they don’t know which one yet.
Therefore, they’ve hypothesized it might be the repetition of oceans colliding, the atmosphere moving, or the fluctuations born of sea and sky alike. If specialists were able to hear the sound clearly, they could discover numerous secrets hidden inside our planet. So, it could even direct them on how to draw a map so aliens can find us. Moreover, a different team of investigators studying the hum in Antarctica said in 1998 that the fluctuations are always sounding.
In 2001, one of them from the University of California at Santa Barbara described that these are “constant signals” that wave in a range of 2 to 7 millihertz, thousands of times lower than the range humans can hear. Scientists haven’t cracked the code yet, but this new breakthrough could help them get closer to the source of this mysterious noise.
Nonetheless, something is somewhat clear: all of them thought the noise was being caught more evident every time. Spahr Webb, a seismologist at Columbia University, is one of the principal researchers in the 21st century who is centered on learning the cause of the hum. Thus, he overruled that the main reason is the communication between the atmosphere and the ground.
In its place, he thought that the primary cause was the ocean waves, which bang on the seafloor “pretty much all the way throughout the Earth.” Further, there are moments when two dissimilar waves collide with one another, sending the vibrations they produce deep down the Earth’s crust. Furthermore, there are also other waves that, instead of shocking them, hit the ground with enough force to create a reaction inside the world. The hum was proposed to be induced by acoustic resonance between the atmosphere and the solid Earth, but this can only explain a part of its amplitude.
