Yall know Im nutts to begin with, and for all of the science schooling I had I cannot figure out what this might be.
I don't buy the official explanation as it seems to differ from event to event, country to country.
My wife has even heard this noise up north in the middle of nowhere.....so what do you think? This is being experienced all over the world for the better part of a few years now growing with frequency. I have studied the phenom ad nausea and still cannot come up with a logical explanation for the events occurring in multiple areas and random duration...as well as random manifestation of sound when others here them.
Some videos you find are a hoax...yet many after analysis are not and are genuine.
