Two ultra-sensitive tests were performed in the chamber. Microsofts anechoic chamber consists of six layers of concrete and steel and sits atop an array of vibration-damping springs. In the Radio Frequency (RF) setting, by coating them with RF absorbing fabrics, the reflective walls of the shielded space are rendered invisible or anechoic.
