Experiments are controlled by two personal computers with specialized audio hardware capable of generating 8 channels of CD-quality sound. A well-equipped audio rack includes instrumentation necessary for stimulus control and measurement. Four high-end workstations with 14 gigabytes of disk storage, and two Xterminals, are used for data analysis, graphics, and modeling. The Auditory Localization Facility at the Armstrong Laboratory consists of a 14-foot geodesic sphere with 277 high fidelity speakers, housed in an 8,000 cu. Special switching hardware allows from 1 to 15 individual sounds to be presented from arbitrary spatial locations.
Extensive instrumentation is available for experiment control and stimulus measurement.
