An Interdisciplinary Synthesis of Reverberation Viewpoints
Barry Blesser   867
Artificial reverberation is much more complex than a simple signal processing problem because it involves issues related to acoustics, perception, statistics, mathematics, music, and culture. While there is a large amount of research in each of the relevant fields, there has not been a significant integration of these disparate topics. Moreover, reverberation is a subset of the larger topic, auditory spatial awareness, which has not been extensively studied. The interdisciplinary approach resolves questions which could not be answered within a specific field. A comprehensive bibliography provides the basis for additional reading and research in critical topics.

Direct Comparison of the Impact of Head Tracking, Reverberation, and Individualized Head-Related Transfer Functions on the Spatial Perception of a Virtual Speech Source
Durand R. Begault, Elizabeth M. Wenzel, and Mark R. Anderson   904
Sound localization using headphones, which is critical to virtual displays, is dependent upon several independent variables including head-tracking, individual head-related transfer functions, and reflection patterns. This experiment determines the relative importance of each factor using a consistent paradigm with a speech signal. With inadequate localization information, errors manifest themselves in terms of localization deviations, front-back reversals, and in-head location. The results serve as a guide in the design of such systems.
