Cornelius Frankenbach: Localization Accuracy in Dynamic Binaural and Near-Field Transaural Synthesis: Influence of HRTF Individualization and Crosstalk Cancellation

IHTA Seminarraum (60 Persons) and Zoom-Meeting (Hybrid) Kopernikusstr. 5, Aachen

Binaural synthesis is a reproduction technique that enables auditory displays of virtual sound sources (VSSs) using head-related transfer functions (HRTFs), which characterize the acoustic paths between a sound source and the listener’s eardrums and are therefore as unique as the head and pinna geometry. Since individual HRTF measurement is impractical for most applications, generic dummy-head […]

Nazli Ekitmen: Perceptual Evaluation of Geometric Details in Road Traffic Auralization

IHTA Seminarraum (60 Persons) and Zoom-Meeting (Hybrid) Kopernikusstr. 5, Aachen

Urban traffic noise is commonly simulated using prediction models that cannot determine what influence small-scale roadside structures have on the perceived qualities. This thesis investigates whether the presence of a sidewalk produces perceptible differences in simulated road-traffic noise compared to a simplified street model that is flat and omits the elevated sidewalk. A three-alternative forced […]

Melchior Käppel: Multimodal Investigations of Listening Effort in Children Across Speech Intelligibility Levels

IHTA Seminarraum (60 Persons) and Zoom-Meeting (Hybrid) Kopernikusstr. 5, Aachen

Listening under challenging conditions can be effortful and requires considerable cognitive resources. This is particularly relevant for children, for whom speech understanding is integral for learning and development. The Framework for Understanding Effortful Listening (FUEL) suggests that invested listening effort does not increase indefinitely with task demands, as motivation is an important factor in determining […]
