The acoustic propagation of sound in the free field or indoors can be calculated efficiently and in high quality by geometrical acoustics simulation methods. However, different geometrical approaches such as ray tracing and radiosity use different approaches to simulate an acoustic environment. In this thesis, the quality and the performance of these different approaches are […]

Research in the field of auditory selective attention continues to evolve, with an increasing interest in creating more realistic testing conditions. Therefore, a previously validated paradigm for investigating auditory selective attention had been extended with spatial auditory reproduction and realistic noise conditions. Building on recent endeavors in exploring the usability of immersive virtual reality in […]

Room perception has different perception levels and influences which can have an impact on the perception. The rooms can be estimated uni-modal and multi-modal. In this thesis, the influence of an incongruency of audiovisual cues in different classroom scenarios is examined. For that, a listening experiment was designed and conducted with 18 normal-hearing and normal-seeing […]
