Current Research

My research aims at understanding auditory cognition in simple and complex environments with the long-term vision to improve future hearing technologies, diagnostics, and therapies. To this end, I combine computational modeling with psychoacoustics and cognitive neuroscience methods while being committed to open and reproducible research allowing the scientific community to be fair and efficient. So far, most of my previous work focused on spatial hearing and revealed 1) how spectral cues induced by the acoustic filtering of incoming sounds by the pinnae, head, and body are processed by the normal and impaired auditory system in order to localize sounds (Baumgartner et al., 2014, 2016), 2) that perceptual biases for looming sonic motion are not cue-specific and originate early during cortical processing (Baumgartner et al., 2017), and 3) that the entirety of auditory spatial cues needs to be consistent in order to effectively engage selective attention networks (Deng et al., 2019).

In this short online lecture I explain further details about my current research:  ÖAW Science Bites: Gefahr – wie wir sie hören. (German only)
