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 […]
Optoacoustic stimulation is an umbrella term describing the generation of mechanical vibrations through optical irradiation and has recently attracted attention as a potential principle for light-driven hearing-aid systems. One specific mechanism underlying this effect is thermoelastic bending, referred to in this work as thermoelastic excitation. While previous studies have mainly investigated simplified artificial membrane models […]
Die realitätsnahe Simulation der Schallausbreitung in urbanen Umgebungen ist von zentraler Bedeutung für zahlreiche Anwendungsfelder wie Virtual Reality, Lärmkartierung und Auralisation. Eine besondere Herausforderung stellt dabei die Modellierung von Beugungseffekten dar, also der Schallausbreitung um Hindernisse wie städtische Gebäude. Klassische Methoden der geometrischen Akustik wie das Raytracing erfassen diese Effekte nur unzureichend. Erweiterte Verfahren wie […]
The evolution of modern mobility has shifted the role of vehicles from being solely a means of transportation to multifunctional spaces where passengers engage in work, communication, entertainment, and rest. With this transformation, the concept of comfort within the vehicle has expanded to include not only physical and ergonomic factors but also psychological needs such […]
Real-life listening is inherently complex. Everyday environments rarely provide clear speech in anechoic conditions. Instead, they often contain multiple partially masking sound sources, varying spatial configurations, and room acoustic reflections. Moreover, listeners typically rely not only on auditory, but also on visual cues, such as lip-movement, gestures, gaze, and embodiment. Thus, listening performance in such […]
