The World's Largest Anechoic Chamber"The architecture, engineering, and construction support services for this major complex have been provided since 1987 by DMJM (DBA Holmes & Naver, Inc.). The anechoic chamber supports ground testing of electronic warfare systems on full-scale aircraft and is a massive 250 x 264 x 70 foot steel plate box enclosed in a metal hangar building. The walls, ceiling, and floor are covered in 816,000 pyramidal foam cones designed to absorb radio frequency signals, and the chamber is RFI shielded to over 100dB. The center of the chamber is equipped with a 160 foot diameter turntable capable of rotating a full 360 degrees while holding objects with a mass of over one million pounds!"
