Evaluation of near field distance perception in virtual environments
175th Meeting of the Acoustical Society of America
Binaural synthesis of spatial audio for virtual and augmented environments is typically performed by convolving an anechoic signal with impulse responses measured at the listener’s ears using a source at a fixed distance. This method is accurate for sounds presented at the measured impulse response’s distance, and for more distant sources, decreasing intensity provides a reasonable approximation. However, sources nearer than 1 m provide additional distance cues.
