Abstract
In many applications, the primary goal of a spatialized audio cue
is to direct the user’s attention to the location of a visual object of
interest in the environment. This type of auditory cueing is known
to be very effective in environments that contain only a single visual target. However, little is known about the effectiveness of this
technique in environments with more than one possible target location. In this experiment, participants were asked to identify the
characteristics of a visual target presented in a field of visual distracters. In some conditions, a single auditory cue was provided.
In other conditions, the auditory cue was accompanied by one or
more audio distracters at different spatial locations. These conditions were compared to a control condition in which no audio
cue was provided. The results show that listeners can extract spatial information from up to three simultaneous sound sources, but
that their visual search performance is significantly degraded when
more than four simultaneous sounds are present in the stimulus.
