Auditory Neuroscience Laboratory

Lab head: Simon Carlile
Location: F13 - Anderson Stuart Building

The Auditory Neuroscience Laboratory hosts a multidisciplinary research program examining auditory spatial perception and its dependent neural processes. These studies blend together bioacoustic, psychophysical, neurophysiological and computational modelling approaches with state of the art, virtual space technologies. Research is currently focused on how the auditory system solves the 'cocktail party' problem; that is, our amazing ability to focus on a particular conversation of interest occurring against a noisy background.

These projects are examining the nature of the acoustic cues available to the auditory system, the way in which differences in the spatial locations of the sound sources are exploited, the perceptual encoding of speech and the role of auditory spatial attention. The results of this pure research are feeding into a practical development program, in collaboration with VAST Audio Pty Ltd, to produce a radical new spatial hearing aid. The laboratory is playing a key role in the clinical testing and commercialisation of this technology.

Perception of stationary and moving sound sources

Primary supervisor: Simon Carlile

Human psychophysical studies examining the role of spectral cues produced by the outer ear and head in generating our percept of external auditory space, and the localisation and streaming of auditory objects within that space. In this approach bio-acoustical measurements of the filtering of the outer ear are used to generate and manipulate sounds in virtual space. Here, digital signal processing is combined with classical auditory psychophysics to study the perception of stationary and moving sound sources.
