Timbre perception and object separation with normal and impaired hearing
Timbre is a combination of all auditory object attributes other than pitch, loudness and duration. A timbre distortion caused by a sensorineural hearing loss not only affects music perception, but may also influence object recognition in general. In order to quantify differences in object …

Neural representations of pitch : role of peripheral frequency selectivity
… speaker identity. Pitch plays a major role in auditory scene analysis: differences in pitch are a major cue for sound source segregation, while frequency components that share a common fundamental frequency (FO) tend to be grouped into a single auditory object. In psychophysics, a positive …

Representation of statistical sound properties in human auditory cortex
… of statistical sound properties in human auditory cortex. It addressed four key aspects in auditory neuroscience: the representation of different analysis time windows in auditory cortex; mechanisms for the analysis and segregation of auditory objects; information-theoretic constraints on …

Influence of spatial cues on the identification and the localization of objects in the auditory foreground
The ability to form auditory objects is important in the natural environment where sounds arriving at our ears are a resultant of all spectro-temporal components that may have arisen from different auditory events. It has been shown that auditory spatial cues are effective for grouping acoustical …

Memory-related cognitive modulation of human auditory cortex: Magnetoencephalography-based validation of a computational model
… modulation of the response properties of human auditory cortex. However, the underlying neuronal mechanisms are not well understood yet. In this dissertation I present a novel approach for integrating 'bottom-up' (neural network modeling) and 'top-down' (experiment) methods to study the dynamics …

Tone-noise dichotomy : investigating tonal content magnitude & pitch strength
Die Arbeit untersucht die Ton-Rausch-Dichotomie hinsichtlich zweier Aspekte, der Tonhaltigkeit und der Ausgeprägtheit der Tonhöhe (AdT). In einer interkulturellen Untersuchung wird der Perzeptionsraum von Rauschen und Tönen mit einem semantischen Differential in Japan, Frankreich und Deutschland …
