The scattering coefficient is a crucial parameter in acoustics, as it plays a significant role in characterizing the scattering of sound waves from surfaces and materials. In this study, we […]

Many public authorities strive for creating more livable cities in future. To better understand what parameters need to be optimized to achieve this, it is necessary to study how humans […]

Die Berechnungszeit eines Audioblocks ist für Echtzeit-Auralisationen von entschei- dender Bedeutung, da sie die realisierbare Latenz nach unten begrenzt. Diese Arbeit untersucht die Auswirkung verschiedener Konfigurationsparameter auf die Laufzeit der […]

Abstract: In this thesis, the processing of verbal and tonal stimuli in the brain was investigated. It was assessed whether implicit pitch-to-digit as sociations influence performance in a verbal serial […]

The acoustic scattering of surfaces is very important in all aspects of room acoustics like in concert halls and reverberation rooms. The sound propagation can be calculated effectively and in […]

Ambisonics ist ein weitverbreitetes Audiowiedergabeformat zur lautsprecherbasierten Reproduktion räumlicher Schallfelder. Klassische Ambisonics-Decoder basieren auf der Annahme ebener Wellen. Damit eine Fernfeldnäherung ebener Wellen für die Lautsprecher zulässig ist, müssen diese […]

Das Ziel der Arbeit war, den Zustand der Raumakustik in Hörsälen der RWTH Aachen University zu erfassen und die Daten zu evaluieren. Dazu wurden Messungen der Raumimpulsantwort in neun Hörsälen […]

Kommunikation ist ein wichtiger Bestandteil der sozialen Interaktion im Alltag. Der kognitive Aufwand für das Verstehen und Verarbeiten von Sprache wird als Höranstrengung bezeichnet. Diese ist unter anderem abhängig von […]

In this thesis the influence of room acoustics on auditory selective attention was examined. A hearing experiment in virtual realty was conducted with 16 normal hearing and normal seeing participants […]

Aircraft sound emissions are often associated with health risks for humans. Consequently, reducing the noise levels has been a research goal for many years. However, a simple level reduction does […]

This thesis focuses on investigating the effects of atmospheric attenuation when employing scale models, with the ultimate goal of improving their application in the study of noise in urban regions. […]

This thesis focuses on learning a measuring method for the determination of the acoustic characteristics of porous materials within a reverberant room setting. Using a supervised learning approach, this research […]

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 […]

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 […]

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 […]
