    Current Research

    Robert Baumgartner is working on computational auditory models and conducts auditory cognitive neuroscience related to spatial hearing with a special focus on the processing of spectral cues induced by the acoustic filtering of incoming sounds by the pinnae, head, and body.

    Description of his current research project SpExCue:

    Sound sources in natural environments are usually perceived as externalized auditory objects that are located outside the head. In contrast, when listening via headphones or hearing-assistive devices, sounds are often heard inside the head, presumably because the acoustic filtering of incoming sound becomes inconsistent with normal experience. Although it is well-known that the high-frequency spectral cues mainly induced by the pinnae encode the sound direction, it is less clear how the salience of these cues affects sound direction and especially externalization. Robert Baumgartner aims at establishing a model for the role of spectral cues in sound localization including externalization. In order to gain insight into the auditory processing of spectral cues and to obtain reliable estimates of externalization, subjective psychoacoustic estimates are related to objective behavioral (reaction time) and physiological (auditory-evoked potentials) measures. The derived objective measures can then be used to extend and improve computational models of sound localization.
