A Novel Sound Localization Experiment for Mobile Audio Augmented Reality Applications

摘要: This paper describes a subjective experiment in progress to study human sound localization using mobile audio augmented reality systems. The also serves validate new methodology for studying where the subject is outdoors and freely mobile, experiencing virtual objects corresponding real visual objects. Subjects indicate perceived location of static source presented on headphones, by walking position auditory image coincides with object. novel response method accounts multimodal perception interaction via self-motion, both ignored traditional experiments performed indoors seated subject, minimal stimuli. Results six subjects give mean error approximately thirteen degrees; significantly lower discrete binaural rendering than ambisonic rendering, insignificant variation filter lengths 64, 128 200 samples.
