Synthesis of Auditory Localization Cues for Cockpit Applications*

The long-term objective of this work is to develop techniques for conveying accurate spatial information via audio signals delivered to the listener through headphones. Specific objectives of the first phase included the design, fabrication, and evaluation of an apparatus for demonstrating simulated auditory localization (SAL). The design of the SAL facility is described. An experimental test of the psychological fidelity of the SAL facility is summarized. The results show that the facility produces a high-fidelity simulation of normal, unaided auditory localization.
