Volker Hohmann, from the University of Oldenburg, will give a seminar on "Model-based signal processing for hearing aids" on Thursday February 26 2009 at 3:15pm in room 52.321 of the Communication-Poblenou Campus.

Abstract: The aim of the work presented in this talk is to investigate potential applications of models of human auditory processing to signal processing in hearing aids. Firstly, implications of using nonlinear peripheral auditory models for the design of dynamic compression systems for hearing aids are discussed. In particular, results from a multi-band instantaneous compression scheme are presented, which is based on a novel nonlinear auditory filterbank controlled by the instantaneous frequency calculated in frequency sub-bands. Secondly, a general framework for computational auditory scene analysis (CASA) is introduced and applied to the problem of estimating spatial direction and spectral envelope of super-imposed sound sources from a binaural input signal.
