There has been a lot of FReepmail on the subject. Stuff people didn’t want to post in the open.
I was one who heard a strange sound in Jan of this year. It was different from anything I heard before. Below is what I posted back in Jan.
Last evening I was in my back office with the door open. A cool front moved through. At one point I did heard such a strange sound that I stopped to take notice. It was a ethereal type howling sound. It lasted for about 30 seconds. I never heard anything like it before.
Now, whatever it was, I attribute it to the a natural affect of the front moving through. These type of natural sound effects my be getting widespread notice because of youtube, causing people like myself to comment upon them, making it seem more unusual than it is
If this wasn't put on youtube, etc, then I would likely have forgotten about it in a week and made nothing of it.
i live in the mid-west, and back last August, after lunch i was going through a drive-thru to get a coffee, anyway, it was when i rolled down the window to order that i first noticed the sound. It was loud and was like scraping or metal crunching along with a waterfall or rushing sound? i thought it must be road construction? i wish now i had asked the gal at the window if she could hear it, after i got my coffee, i drove around for a few minutes in the immediate vicinity to see what it was, and didn't find anything, or any work being done with heavy machinery. Finally i drove a block or so to a mall parking lot and rolled down the window. The sound level while driving around always stayed the same, I never seemed to get further away from it, or for it to diminish which i thought was odd, i parked for a few minutes to drink the coffee, then i saw two men walking out of a store toward my direction and I watched closely to see how they would react and nothing, they didn't pause, look up or miss a step.
i was running late, so i turned out of the parking lot, drove to the stop light and took one final look across to a K-mart parking lot and again didn't see any work being done, by the time the light changed and i turned the corner, the sound just stopped.
it was strange enough and made enough of an impression that i checked the local paper on-line a few days afterward and found nothing at all reported, if it was a tornado alarm, they need to work on the speakers, this was unusual sounding,
the time of day was approx 12:40 PM to 12:55 PM on whatever day it was, as i had to race back to work,
anyway, i was unaware of any similar reports, and checking the internet headlines using google, i noticed a few discussing something similar, and found just a couple of youtube videos, including the one in Kiev which was about the same time, but what i heard sounded nothing like that,
a month or so ago, the local news reported a lot of folks hearing ‘booming’ sounds, they reported this as ‘sky quakes’ i didn't hear them myself and what i heard was not booming or trumpet like.
The video link posted from the Amarillo radio station, if its not just a publicity stunt/hoax for ratings? sounded just like the Kiev video? what you do with this info i have no idea, just fyi
