ABSTRACT
In the past few years, the increase in interactive use of computers has led to an emphasis on human factors and the ways in which digital information can best be presented to users. Computer graphics has been at the forefront of this growth involving vision as an active aid in interpreting data. Bar charts, psuedo-color image processing, and 3-dimensional figures are but a few means of providing the viewer with data information.
As the use of computers increases, the need for a variety of alternatives of interacting with computers also increases. Computer-generated sound is one capability not being fully utilized in the computer/human interface. Just as an x-y plot reveals relationships in data, sounds might also reveal relationships in data. This report focuses on the potential for using computer generated sounds to present data information. The first section addresses multivariate data problems which might be aided by sound output. The second describes experiments performed to determine whether listeners can discriminate among data sets based on sound. The final section discusses ongoing work and future directions.

Immersive auditory display system 'sound cask': three-dimensional sound field reproduction system based on the boundary surface control principle
VRST '18: Proceedings of the 24th ACM Symposium on Virtual Reality Software and TechnologySound cask was developed to realize the perfect 3D auditory display that creates 3D sound waves around the listener's head just the same as the primary sound field, based on the boundary surface control (BoSC) principle.
If we consider the sound ...
Virtual Sound Rendering in a Stereophonic Loudspeaker Setup
This paper presents a mathematical analysis of the effects of interchannel amplitude and time differences in two channel (stereophonic) sound systems. The analysis is developed by computing the acoustic conditions at the listener's ears as a function of ...
