In Reply to: RE: The quietest place on earth: anechoic chamber posted by G Squared on October 19, 2015 at 12:17:35:
The RF anechoic chamber at GM was audibly quiet and we had fun playing around yelling into the corners. I imagine it wasn't as acoustically quiet in the audio range as a chamber designed specifically for audio frequencies.
They used various antennas like small log periodic beams to not only blast the cars with RF but to observe the car's own RFI on spectrum analyzers. I wasn't directly involved with that testing but the GM engineers who hosted my months long visit showed me around. It was a fun place!
