SUMMARY:Bender: Internship at HEAD acoustics GmbH - NVH department
DESCRIPTION:This presentation will give an overview on my internship in the NVH (noise-vibration-harshness) research department of HEAD acoustics. First\, the company and the work environment are introduced. As my tasks were based on psychoacoustic metrics\, I will give a short introduction into this topic. Lastly\, some tasks handled by me during the internship will be explained. \nMelden Sie sich hier an um Einladungen zu den Kolloquium-Vorträgen per E-Mail zu erhalten.\nRegister here to receive the invitations to colloquium talks via e-mail. \nZoom-Meeting-ID: 954 4073 3814\nPasswort: 450783

SUMMARY:Schmitz: Internship with HEAD acoustics GmbH - Telecom department
DESCRIPTION:The presentation will be about my tasks and activities at HEAD acoustics GmbH. During the entirety of my industrial internship\, I was part of the Telecommunications Research and Standardisation department. The main topic of the talk is spatial audio (Ambisonics) and the development of suitable audio codecs and standards for such signals. First\, I will discuss the question of how to evaluate the acoustic performance of Ambisonics codecs and what could be a possible test signal for it. Second\, I will talk about my involvement in the generation of test signals for speech and background noise for a future codec. \nMelden Sie sich hier an um Einladungen zu den Kolloquium-Vorträgen per E-Mail zu erhalten.\nRegister here to receive the invitations to colloquium talks via e-mail. \nZoom-Meeting-ID: 954 4073 3814\nPasswort: 450783

SUMMARY:Ye: Examining in influence of virtual agents on the auditory selective attention in an audiovisual classroom scenario
DESCRIPTION:This study investigates the influence of virtual humans on auditory selective attention within a virtual reality (VR) environment. Auditory selective attention is a well-established phenomenon that affects our ability to focus on specific sounds while filtering out distractions. Previous research has demonstrated that visual cues\, such as seeing the talker’s face\, can enhance listening abilities. However\, the specific impact of virtual humans on auditory selective attention in VR has not been extensively explored. The hypothesis of this study posits that the presence of virtual agents in the VR environment\, or fixed voice characteristics\, would enhance auditory selective attention performance. To test this hypothesis\, the experiment was conducted using a VR environment built in Unity\, incorporating relevant plugins to enhance the functionality of virtual agents. Contrary to expectations\, the obtained data did not provide sufficient evidence to support the hypothesis. The results did not demonstrate a significant improvement in auditory selective attention performance when virtual agents were visible or/and a fixed voice is attached to every position in the VR environment. While the results did not align with the initial expectations\, some interaction effects are shown in the result. Further research is warranted to explore alternative factors and experimental conditions that may influence auditory selective attention in the context of virtual humans in VR. \nMelden Sie sich hier an um Einladungen zu den Kolloquium-Vorträgen per E-Mail zu erhalten.\nRegister here to receive the invitations to colloquium talks via e-mail. \nZoom-Meeting-ID: 954 4073 3814\nPasswort: 450783

SUMMARY:Mika: Filter creation for partially absorbing surfaces in the Image Edge Model
DESCRIPTION:The generation and propagation of noise is an ongoing research topic that affects everyone. Urban environments in particular suffer from high levels of noise pollution\, which can negatively impact the health and well-being of citizens. It is therefore essential to understand the propagation of sound from one or more sources to a receiver. However\, human perception of sound is highly subjective\, making generalisation and research very difficult. A common way to gain insight into sound propagation is through computer aided simulation. The image edge model is one such simulation model that identifies all significant sound paths from one or more sources to a receiver\, before calculating transfer functions for each path. It is designed for urban environments and is based on the geometric acoustics approach\, while including diffraction using the Uniform Theory of Diffraction. However\, specular reflection is handled by simply reflecting on each surface with a constant reflection factor. This does not accurately capture the effect of different materials\, which exhibit frequency and angle dependence\, on the reflected sound levels. In this thesis\, the existing image edge model workflow is revised\, enabling material-aware specular reflection that considers these factors. Specifically\, the hypothesis that material-aware specular reflection lead to different and more plausible transfer functions is investigated. To achieve this goal\, two new implementation types are created and com- pared against the old\, constant reflection factor. Validation results using the Benchmark for Room Acoustical Simulation (BRAS) dataset show\, that material-aware specular reflection overall significantly outperforms the old implementation type\, especially for absorbing materials. This supports the hypothesis that material-aware specular reflection leads to improved transfer functions. \nMelden Sie sich hier an um Einladungen zu den Kolloquium-Vorträgen per E-Mail zu erhalten.\nRegister here to receive the invitations to colloquium talks via e-mail. \nZoom-Meeting-ID: 954 4073 3814\nPasswort: 450783
