Abstract
"In order to create a three-dimensional virtual auditory display, both source direction and source distance must be simulated accurately. Echoes and reverberation provide the most robust cue for source distance and also improve the subjective realism of the display. However, including reverberation in a virtual auditory display can have other important consequences: reducing directional localization accuracy, degrading speech intelligibility, and adding to the computational complexity of the display. While including an accurate room model in a virtual auditory display is important for generating realistic, three-dimensional auditory percepts, the level of detail required in such models is not well understood. This paper reviews the acoustic and perceptual consequences of reverberation in order to elucidate the tradeoffs inherent in including reverberation in a virtual auditory environment."
