Hello, i have heard a weird humming sound, off and on since about oct 2014. first time i thought it was coming from tv, at 12:30 am, not sure exact date. anyway, after i couldn't locate source inside, i went out the front door to listen so i could figure out what the heck it was. this sound is very peculiar and i half expected to look up to see something. i did not. but i have travelled all over within a mile or so from my house and this sound is exactly the same, coming from all directions. several of my neighbors have heard it and i have spoken to other people from western co who have heard it too. whatever it is from, it seems to me that it must be associated with a great deal of power, because it must have very large wavefronts, or else you would be able to tell its direction. based on descriptions i've seen of the taos hum, this is not the same, this being a higher frequency. it is still occurring at 11:03 pm mst and has changed pitch slightly (lower) since approx 10:35 pm.
