The Acoustic Research Laboratory at NASA's Langley Research Center houses several of the major acoustic research facilities. The primary research facility is the Quietflow Aerocoustics Facility that includes a 20 ft x 24 ft x 30 ft anechoic chamber with two open-jet wind tunnels. Facilities for testing human response to sonic booms, outdoor aircraft flyover noise, and aircraft interior noise are also in the laboratory.
