Signal analysis in the human auditory system

Foredraget foregår på engelsk.
How does a physical event that is characterized by acoustical waves entering our outer ear produce an auditory sensation? A major aim of hearing research is to establish a functional relationship between the basic physical attributes of a stimulus, such as the intensity or the spectral content, and their associated percepts. It is the combination of sensory psychoacoustics, electrophysiology (e.g. acoustically evoked potentials) and neuroimaging (e.g. magnetic resonance imaging) that nowadays allows for a deeper understanding of the relationship between our (acoustic) environment, its internal representation, and (auditory) sensation. This talk considers three main stages of signal transformation in the human auditory system that represent fundamental processes of frequency analysis, time analysis, and pattern recognition. While the research mainly deals with fundamental principles of neural modeling and strategies of auditory signal processing and perception, many findings can be useful for technical and clinical applications, such as improved man-machine communication by employing auditory-model-based processing techniques, or new processing strategies in digital hearing aids and cochlear implants.
