Funny you should mention this now. Just a couple of weeks ago, I heard a sound like some of these & after a minute or so, realized it was a motorcycle (the “crotch rocket” type) going flat out & quite a ways off. I guess that wouldn’t explain it in a really remote location, though. I wondered then what had ever happened with it.
Last account, I think it was supposedly a water phone & there was something about a movie trailer.
Prairielady, I just googled & maybe it’s an “alpenhorn” or a labrophone you’re referring to?
No idea what this is & never hope to find out! What is up with those people who go outside & walk around, trying to see where it’s coming from? Waaay too creepy.
Yes, that’s the one..that alpine horn..
What we did was use a search engine to find the sounds of instruments so some of what we found were a single sound.
