Foam Spikes Create Echo-Less, Silent Research Chamber [Pics]
The Radio Anechoic Chamber at Denmark's Technical University is designed to absorb radio waves.
The Radio Anechoic Chamber at Denmark’s Technical University, operated with the European Space Agency (ESA), is a research facility mainly used to test antennas. It opened in 1967 and has provided the ESA with accurately calibrated antennas for more than twenty years.
The blue chamber minimizes any reflections of microwaves and the large foam spikes scattered around the space are filled with carbon and iron to absorb radio waves. This chamber can be used to conduct experiments where exterior noise/sounds could affect the scientific findings. Also it is very effective for testing the effectiveness of antennas, and also helps to simulate the conditions of space.
