A psychophysically-derived control for the perceived range of a virtual sound source was implemented for the Pioneer Sound Field Controller (PSFC), a spatial auditory display employing a 15-loudspeaker hemispherical array. Capable of presenting two independent sound sources moving within a simulated reverberant environment, the PSFC primitives include parameters to manipulate source azimuth and elevation, and also the size and liveness of the simulated space. As accurate control of virtual source range was confounded by variations in both the liveness parameter and in overall PSFC channel volume, an empirical approach was employed to derive a Look-Up Table (LUT) inverting the average range estimates obtained from a group of human subjects who listened to a set of virtual sources (short speech samples).
