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 […]

Audiovisuelle Sprache verbessert im Allgemeinen, aber insbesondere unter ungünstigen Hörbedingungen, die Sprachverständlichkeit, indem sie ergänzende visuelle Informationen liefert. Es bleibt jedoch unklar, ob sich diese Wahrnehmungsvorteile auch in einer verbesserten Arbeitsgedächtnisleistung niederschlagen oder ob die Integration von auditiver und visueller Sprache zusätzliche kognitive Kosten mit sich bringt. Bisherige Studien konnten die potenziellen Integrationskosten nicht ermitteln, […]

Accurate determination of acoustic ground impedance is essential for predicting sound propagation over outdoor surfaces. However, the measurement process is affected by uncertainties arising from the experimental setup, particularly from variations in source and receiver positioning. The objective of this thesis is to investigate how geometric uncertainties propagate through impedance measurement procedures and influence the […]
