I ran across an interesting article here at the office:
http://www.army.mil/-news/2010/06/15/40847-armys-world-class-facility-enhances-auditory-research/In order to support this research, the EAR facility has been designed to be re-configurable to simulate a wide range of indoor and outdoor acoustic environments. A researcher's ability to re-create soundscapes from both urban and rural surroundings is an important property and just one example of the many capabilities of the facility.
It sounds like the beginnings of the ultimate sound room.
