Inertial Head Tracking for 3D Audio (Project "Sound Advice")
Abstract
This report presents the results of a limited evaluation of a 3D Audio system on board a USAF C-12C aircraft under two system configurations: 3D Audio system coupled to a reference navigation system, and 3D Audio system coupled to an inertial head tracker. Testing began on 14 Oct 2004 and was completed on 2 Nov 2004 after eight sorties. Inertial head tracker angular accuracy when coupled to the aircraft frame was compared to the reference navigation system. The ability of the 3D Audio system to generate discernable directional sounds in ground and flight conditions was evaluated. The capability of the 3D Audio heading cue to provide heading information to the pilot with sufficient fidelity to fly to a specific heading was evaluated. Pilot orientation threshold was measured as the point where the pilot was aware that the aircraft was offset from level flight and could make a determination of offset direction (pitch up, pitch down, roll left, roll right) with no visual references. The system's capability to provide attitude information to the pilot to maintain vision-restricted straight-and-level flight was also tested.
