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
Glad to have read both your posts. Here is the original thread I took note of with fellow FReepers who have experienced this.
Within the thread is a link to another with more FReepers who have heard it. I have not and really don’t think I want to.
You two might contact some of these FReepers and compare notes. Might help you sort things out.
