Could it be picking up audio through the structure? That'd still attenuate the highs, though. If the chamber isn't at any vacuum whatsoever, what is the function of the membrane? Only other thing I can think of is helping contain shrapnel if the thing disintegrates inside. And that's really weird, we actually didn't use Ikea products in any of the labs that I know of. I guess, uhh, that's just the future. Like SpinLaunch.
it's been a part of their marketing it's bloody well gonna be there in the puff piece, dude. Kinda like how they had to show the damn thing spinning through the air like a goddamn boomerang and then go "no no no that's it heating up from the atmosphere ignore how it cools right back down and heats back up and cools back down and heats back up." The fact that you can see the yaw of their shotput in the tiny field of view of the exit shows you just how much English they put on that ball.If the chamber isn't at any vacuum whatsoever, what is the function of the membrane?
