Abstract
Spatial audio displays are created by processing digital sounds
such that they convey a spatial location to the listener. These displays
are used as a supplementary channel when the visual channel
is overloaded or when visual cues are absent. This technology can
be used to aid decision-makers in complex, dynamic tasks such as
urban combat simulation, flight simulations, mission rehearsals,
air traffic control, military command and control, and emergency
services. Accurate spatial sound rendering is a primary focus in
this research area, with spatial sound memory receiving less attention.
The present study assesses the effects of visual augmentation
on spatial sound location and identity memory. The chosen visual
augmentations were a Cartesian and polar grid. The work presented
in this paper discovered that the addition of visual augmentation
improved location and identity memory without degrading
search time performance.
