We present a study investigating the use of 3D audio for navigation and location of objects in an indoor environment. In order to conduct the study, a custom-made 3D audio system was built based on a public-domain HRTF-library to playback 3D sound beacons through a pair of headphones. Our results indicate that 3D audio is indeed a qualified candidate for navigation systems, and may be especially suitable for environments or individuals where vision is obstructed, insufficient or unavailable.

A comparison of 3D audio, map-based and unaided search shows significant differences between unaided and 3D audio search, as well as between unaided and map search. However, there were no significant differences between map and 3D audio search which is notable. The study suggests that elevation information should be implemented with special cues.
