The above video is real, not editted. These sounds can be found more on youtube and research has been done on these sounds. Apparantly scientists are devided to call it "sighs" of earth, or solar flares causing sound waves. Whatever it is, its creepy as fuck and that scientists are only guessing makes it alot creepier.
That is one nasty sound... if I heard something like that on my way home from work during the night my heart would start pumping... and then someone like this would probably show up and tell me to... Spoiler
Geology + physics. I'd say 'simple geophysics' but I'm not the geophysicist here. They are low-frequency acoustic emissions in the range between 20 and 100 Hz modulated by ultra-low infrasonic waves from 0.1 to 15 Hz. In geophysics, they are called acoustic-gravity waves; they are formed in the upper atmosphere, at the atmosphere-ionosphere boundary in particular.
I've heard these sounds myself once. It was evening and it was pretty scary as i was home alone ... i actually hear it wuit often i have even felt this like pressure on me when hearing the sound it felt like my ears were actually shaking might be smth else tho but its quite scary
