Virtual Audio

Although virtual audio displays are capable of realistically simulating relatively distant sound sources, they are not yet able to accurately reproduce the spatial auditory cues that occur when sound sources are located near the listener's head. Researchers have long recognized that the binaural difference cues that dominate auditory localization are independent of distance beyond 1 m but change systematically with distance when the source approaches with in 1 m of the listener's head. Recent research has shown that listeners are able to use these binaural cues to determine the distances of nearby sound sources. However, technical challenges in the collection and processing of near-field head-related transfer functions (HRTFs) have thus far prevented the construction of a fully functional near-field audio display. This paper summarizes the current state of research in the localization of nearby sound sources and outlines the technical challenges involved in the creation of a near-field virtual audio display. The potential applications of near-field displays in immersive virtual environments and multimodal interfaces are also discussed.

Virtual Audio

One of the greatest weaknesses of current virtual audio displays is their inability to produce robust distance cues. There is, however, reason to believe that the systematic changes that occur in human speech as the loudness of the voice increases can provide distance information in a virtual audio display. In this experiment, speech samples ranging from quiet whispers to loud shouts were processed to simulate live human talkers at 9 distances from 0.25 m to 64 m, and were presented over headphones to listeners in an outdoor environment. The resulting distance judgments indicate that vocal effort has a strong influence on the perceived distance of speech, and that the effects of vocal effort are consistent across a range of talkers, utterances, and listeners. Thus, it appears that speech-based distance cues are capable of providing salient distance information in virtual audio displays.
