IAC, a leader in the design and build of anechoic testing chambers, has recently replaced a chamber for the Bergische University at Wuppertal in Germany. However, there were some unusual features that the project design had to factor in, such as having to house the new anechoic chamber inside a former military headquarters, meaning that the building's thick walls and roof would provide a valuable starting level of noise attenuation.
