Research requiring more rigorous control of lighting environments and sound-levels than is possible in the experimental rooms (ERs) is conducted in the Laboratory's semi-anechoic Blackroom and Audiometric Booth. The Blackroom provides a completely "light tight" environment and is, for example, capable of supporting the research, development, and evaluation of advanced visual display technologies.
The Audiometric Booth is, for example, capable of supporting the research, development and evaluation of advanced auditory display technologies, supporting subject-matter expert hearing tests, and supporting the simulation of operational environments where auditory criteria are critical.
