Binaural auditory scene analysis for hearing aid applications: next generation of classification systems and signal enhancement
Summary:
In this project we will investigate features that go beyond the dimensions typically used (time, frequency, angle of incidence) in hearing aids. These features may be the “onset time instances”, “pitch frequencies”, and “signal modulation”. In combination, the typical dimensions and the new features span an “auditory space”. This approach allows a sophisticated analysis and filtering of the hearing aid signals especially with respect to number of sources present and the type of sources. Based on this information, a classification of the environment should be possible. The target is a more sophisticated and more precise classification and in consequence a more precise – including high time precision – setting and/or parameterization of signal processing algorithms.
