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 […]

Traffic noise is an important public health issue and factor of annoyance. Auralization enables its perceptual evaluation in virtual environments. In outdoor sound propagation simulations, however, geometric modeling often focuses on large-scale features, while smaller roadside structures are neglected or simplified. For vehicle noise sources located close to the ground, roadside structures of similar height […]
