Abstract
We have designed a system suitable for auditory electroencephalographic (EEG) experiments,
with the objective of enabling studies of auditory motion. This thesis details the
perceptual cues involved in spatial auditory experiments, and compares a number of spatial
panning algorithms while examining their suitability to this purpose. A behavioural experiment
involving perception of static auditory objects was used in an attempt to differentiate
these panning algorithms. This study was used to inform the panner choice used in an auditory
EEG experiment. This auditory EEG experiment involved the effects of discontinuity
in velocity and position, and their affects on object perception. A new event related potential
(ERP) component – the lateralized object related negativity (LORN) – was identified,
and we consider its significance. libnetstation, a library for connecting with the NetStation
(EEG) system has been developed, and released as open source software.
