Rummler: Scale Model Study of Audience Related Transfer Functions (ARTF) for Direct Sound and Early Reflections – Internship with Kahle Acoustics srl

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

A 1:20 scale model has been constructed to investigate grazing attenuation by seats and audience at various angles of sound incidence, for both direct sound and early reflections. Transfer functions for a range of azimuth and elevation angles have been measured both for unupholstered seats and with modeled audience: these are referred to as the […]

Rehman: Comparison of VR and web-based listening experiments on the perception in complex auralized environments

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

Audiovisual listening experiments are crucial for understanding acoustical noise and human sound perception. However, traditional VR setups are limited by the need for expensive equipment and time-consuming laboratory sessions. As a result, interest in online experiments has been growing, especially since the COVID-19 pandemic. So far, these experiments have been restricted to basic setups lacking […]

Lobato: Improving sound source localization and characterization with machine learning techniques

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

is thesis addresses key challenges in acoustics applications like troubleshooting, product optimization, and sound source modeling, focusing on the localization and characterization of sound sources using Beamforming techniques and an improved regularization of inverse methods. Traditional Beamforming methods, while effective in identifying main radiating sources, are limited by the array size and density, which affects […]
