Anechoic chamber visit.
Apparently, there are two types of anechoic chambers: a full chamber with absorption below an airplane cable floor and a hemi-anechoic chamber with a hard floor. There are also chambers for EMI and RFI radio frequency (RF) measurement. An acoustic chamber completely absorbs all sound reflections, so you only hear the source sounds.
Anechoic chambers test smaller spiral and sinuous antennas: Frequencies from 0.5 GHz up to 100 GHz. RF sources with broadband amplifiers and very wideband rotating linearly polarized horns. The compact range is capable of testing both Radar Cross-Section (RCS) and measuring antenna gain and patterns. It seems almost to have a form of its own. People have been known to go crazy in anechoic chambers. Hallucinations occur. Some feel suffocated; others achieve a meditative calm. If you are alone, and particularly if the lights are turned off (not possible during my visit), a claustrophobia of the self can occur.body that incorporates an anechoic chamber (a room where the walls absorb virtually all the sound) containing a test tyre and Brüel&Kjær microphones.
