Anechoic chambers are all like this, they're utterly soundproof rooms. They're also supposedly only something humans can stay inside for short time periods because it gets uncomfortable when you start to realise you can hear the blood travelling through your own veins because of how silent it is.
This one is set up for whatever the job of this antenna is. I don't know enough about the antenna to comment on it.
I think this room is the same, but for RF rather than sound. It would be used to test various RF equipment without (as much) interference or reflections.
Yeah that makes sense and also makes it more unique than sounds alone.
Yes exactly. This is a room to test for signals, wanted or unwanted coming out of the devices to be tested. I know nothing about it so don't spy on me please lol.
Can confirm. I've been in a room exactly like that, where they had an antenna mounted on one wall like the above picture, an RF reflector mounted on the opposite wall, and RF dampening cones on every surface, so that they could measure the frequency curve at a distance twice that of the size of the room (the curve changes with distance)
It's true! I've been in one and it was uncanny as hell. I've also been in an echoic chamber where the tiniest little footstep or w/e echoes and echoes and echoes
Wouldn't be me, I'm built different, I got tinnitus
I've been in one and it is weird as hell
