Except these people aren't "hearing things", they heard things. As in they don't keep hearing them anymore, and the sounds were recorded, so actually happened.
I heard that recording. It did not sound loud at all. Im calling bs on it being evidence of an attack.
So turn your volume up?
Yes I did. At max volume it sounds like an annoying buzz. Not loud. Did you even listen to it before snark?
Ok, let me spell it out: saying the recording isn't very loud is a nonsense argument, because it can vary wildly from reality.
Presumably the person recording it was hearing it and wanted a good recording so would have recorded it in the same circumstance as he was hearing it. He would want it to be representative. Thats why he recorded it.

Besides which, they are reporting repeated attacks. So then, why havent better recordings been made? The gear to record microwaves, infrasonics, and ultrasonics is ridiculously easy to come by. If they are interested in figuring it out then why have they not done this?
