Modeling auditory processing of complex sounds
The performance of human auditory processing in decoding the information embedded in complex acoustic scenes is remarkable and exceeds by far current machine performance in terms of robustness, generalization and specificity. Recent experimental evidence from psychoacoustic, electrophysiological and fMRI-studies in humans allows an increasingly detailed insight into the nature of this higher-level auditory processing and demonstrates several of its key features. This talk will introduce such higher-level processes, the computational models found so far, and shows how they could possibly help improve signal processing applications.
Volker Hohmann received the Physics degree (Dipl.-Phys.) and the doctorate degree in Physics (Dr. rer. nat.) from the University of Göttingen, Germany, in 1989 and 1993. He has been a faculty member of the Physics Institute, University of Oldenburg, Germany since 1993 and was appointed full professor in 2012. His research expertise is in acoustics and digital signal processing with applications to signal processing in speech processing devices, e.g., hearing aids. He is a consultant with the Hörzentrum Oldenburg GmbH. He was a Guest Researcher at Boston University, Boston, MA, (Prof. Dr. Colburn) in 2000 and at the Technical University of Catalonia, Barcelona, Spain in 2008. Prof. Hohmann received the Lothar-Cremer price of the German acoustical society (DEGA) in 2008 and the German President’s Award for Technology and Innovation in 2012.
