The Hum, I stick to my early assumptions that "electromagnetic hearing", a direct stimulation of the accoustic centre in the brain, has something to do with it. The brain reacts to electromagnetic input, it works electrical, and if you stimulate according brain areas, you can create an accoustic perception without accoustic soundwaves being involved. I remind of my attempts years ago to describe the strange direction thing of the sound I heard, that when I turned the head, the sound followed to then come from the same subjectively perceived direction again, the direction corrected itself with every head movement to stay in same relative bearing - but with a delay of not more than second maybe. While at the same time being omnipresent and omnidirectional, and being perceivable always at the same volume no matter any environmental noise levels - you could not drown the hum by white sound or loud music or anything. It always is above everythgin else - but always staying at the same volume itself. Its hard to explain, maybe one cannot understand it at all if one has never heard it oneself. Very, very weired. I agree, the descritoion I gove seems to make no sense. And yet it is true in the meaning of that I describe it as correctly as I can.



Maybe imagine airraid sirenes in town, though much, much more silent. The sound they make seems to be everywhere, the hoover in the air, like a layer that puts itself over your reality, a giant blanket covering the world. And yet, one siren near to you you may be able to sort out and give it a direction where it sounds from - while at the same time the overall sirens sound still is from all directions around. Now imagine you turn your head by 90°. You would expect the single sirent chnages the relative direciton to you, that you hear the change in direction. But imagine that instead with a delay of a second or less the siren relocated so that it is at the same relative bearing to you again. Imagine you shake your head, and the sirens follows with its relocations, always with the same delay, no matter the speed of your headshaking.



Now imagine you are in my town and enter the train in the central station, you drive to Osnabrück, that is around 40km in a straight line, notheast from here. The noise of the train, and the centrla station. The city. The traffic. People. Loudspeakers. The hum/siren(s) persists, not louder, not more silent, always staying the same. You ride in the train, and halfway between arrival and destination there is a chain of hills form west to East, the Wiehengebirge, peaks at I think 270m. There is the town Lengerich, and the railway goes through a tunnel. While you are in the tunnel, the sirens all of a sudden shut down. Silence, form one split seocnd to the next! Surprise!


No sirens sound in Osnabrück, and north of Lengerich. Everything normal, as you are used to how it should be.


Later the day you board the train in the opposite direction. No sirens. Then the passage through the tunnel, and when you pop your nose out of it in Lengerich, somebody flips the switch and all of a sudden the sirens are back, the omnipresent sound as well as the directional single one.



The volume is always the same, no matter where you are.



You may understand then why I am so perplexed and confused, irritated and fascinated, and sometimes even was worried a bit.


In the video the author says he thinks there is not just one explanation for the hum, that it might be a combination of several factors. Well, there I disagree a bit. I think that maybe there is not just one hum phenomenon, but that we are talking about different phenomenons maybe, all summarising them - wrongly - under the same label.



If it would have been a brain issue, a tumor or something, I would strongly assume by now I would have felt more threatening consequences from that. Instead: nothing. No, I stick to that electromagnetical hypothesis.
