  • Haoyue Liu: Uncertainties in Acoustic Surface Impedance Measurement

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

    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 […]

  • Cosima A. Ermert: Simulating complex listening scenarios in audiovisual virtual reality – The impact of audiovisual cues, spatial noise, and room acoustics on listening performance

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

    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 […]
