We (my parents) bought a plot of land a long time ago. We built a house there, it took over a year. We finally finished it up and moved in. A few weeks later, we were in the living room. rrrrRRRRRRRwwwwooooaaahaaaaaaAAAAAAAAWWWWWWWWRRRRRRRRRRRRRRRRWWWWWAAAAAAAaaaaaaawwwwwwwwAAAAAAAAAAWWWRRRRRRRRRRRRRRRRRRRWWWWwwwwaaaaaawwwwwWWWWWAAAAARRRRRRRRRRRRRRRRAWWWWWWWwwwwwwwwwwooooaaahaaaaaaAAAAAAAAWWWWWWWWRRRRRRRRRRRRRRRRWWWWWAAAAAAAaaaaaaawwwwwwwwAAAAAAAAAAWWWRRRRRRRRRRRRRRRRRRRWWWWwwwwaaaaaawwwwwWWWWWAAAAARRRRRRRRRRRRRRRRAWWWWWWWwwwwwwwwwwooooaaahaaaaaaAAAAAAAAWWWWWWWWRRRRRRRRRRRRRRRRWWWWWAAAAAAAaaaaaaawwwwwwwwAAAAAAAAAAWWWRRRRRRRRRRRRRRRRRRRWWWWwwwwaaaaaawwwwwWWWWWAAAAARRRRRRRRRRRRRRRRAWWWWWWWwwwwwwaaawwwwrrrrrrrrr r r r r r r r r r r rr

The windows were rattling, which was neat because they were new and tightly sealed. The doors were rattling, the dishes were rattling

Down in the tree line, half hidden in a grove of trees along a boarder road one property over (maybe 800ft), there was a pretty damned big siren. I’m still somewhat shocked we never noticed it during the construction. No idea what it was, no indication what it was. Just a loud AF air raid style siren. Nothing on the news, no internet or cell phones back then.

After asking the neighbors, it was apparently the test siren for the local nuclear power plant (40 miles away), We had never been there on the first Tuesday of the month at 1pm, so we had never heard it being tested.

More recently, I moved into a new house about 2 years ago. (several moves later) and I was outside on a brisk day. All of a sudden, there was a tonal version of a klaxon, (think LOST) ERRRRRTTTTTT ERRRRRTTTT ERRRRRRRTTTTT ERRRRRTTTTT (3 second pause) ERRRRRTTTTTT ERRRRRTTTT ERRRRRRRTTTTT ERRRRRTTTTT (3 second pause) ERRRRRTTTTTT ERRRRRTTTT ERRRRRRRTTTTT ERRRRRTTTTT (10 second pause) (indistinguishable human speech) WAH ME FNDL WA NAW MAW WAH NENELE FAH WA NA. EFF WANAWA, ME FEDLE ME NO, ME NO MO NO FANALWE FWK THO

We live somewhat near a small airport with a National Guard base attached. In the summer, it’s kinda quiet and far off as it’s a couple miles away. When the air is very cold and the wind blows the right way, it sounds like they’re doing it in my back yard with the exception that the speech is still absolutely unintelligible.
