Pausch: Spatial audio reproduction for hearing aid research: System design, evaluation and application

Zoom-Meeting

Hearing loss (HL) has multifaceted negative consequences for individuals of all age groups. Despite individual fitting based on clinical assessment, consequent usage of hearing aids (HAs) as a remedy is often discouraged due to unsatisfactory HA performance. Consequently, the methodological complexity in the development of HA algorithms has been increased by employing virtual acoustic environments, […]

Witew: Measurements in room acoustics – Uncertainties and influence of the measurement position

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

Regardless of the field, measurements are essential for the validation of theories and for making well-founded decisions. A criterion for the validity and comparability of measured values is their uncertainty. The "Guide to the Expression of Uncertainty in Measurement" (GUM) provides a standardized framework for determining and interpreting measurement uncertainty. In room acoustic measurements, the […]

Imran: Virtual Building Acoustics – Auralization with contextual and Interactive Features

Zoom-Meeting

Building acoustics auralization is used to assess the perceptual aspects of sound transmission in built environments to provide the guidelines for architectural constructions and to evaluate the noise effects on humans. These noise effects have a negative influence on daily-life activities and create disturbances in physical and metal work. These disturbances are present within the […]

Guo: Studying the effect of increased realism on auditory distraction in open-plan offices using headphone-based virtual acoustic methods

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

Open-plan offices have been popular for their significant advantages such as economical savings and flexible layout design. However, according to several questionnaire studies, noise, and in particular, irrelevant speech has been rated as the major source of annoyance in open-plan offices, which impairs concentration severely and causes productivity decline. As the Irrelevant Sound Effect (ISE) […]

Salehi: Ersatzschaltbildmodellierung von Knochenschall

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

Dieser Vortrag beschäftigt sich mit der Ersatzschaltbildmodellierung des Knochenschalls. Die Knochenleitung beschreibt die Übertragung von Schall als Schwingungen im Schädel Knochen und dem umgebenden Weichteilgewebe zum Innenohr. Es gibt fünf verschiedene Wege, die oft als wichtig für den Knochenleitung Schall angesehen werden: Schalldruck im Gehörgang, Trägheit des Mittelohrs, Trägheit der Innen Innenohrflüssigkeit, Kompression des Innenohrraums […]

Burger: Modulating Serial Recall Performance By Audiovisual Target Discrepancies

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

People perceive most events with several senses at the same time. In everyday life, these different sensations coincide in time and space to form one coherent percept. However, in online conferencing, which has become an increasingly popular mean of communication, there may be a temporal and/or spatial mismatch between visual and auditory input, e.g., due […]

Henao Rivera: Examining auditory cues for an auditory selective attention paradigm in virtual reality

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

In recent years, the use of virtual reality in research has greatly increased due to its ability to recreate complicated and realistic circumstances in a well-controlled laboratory environment. In this thesis the use of three different auditory cues in a auditory selective attention experiment in virtual reality is studied and validated, examining which of them […]

Lapparent Alvarez: Examining visual cues for an auditory selective attention paradigm in virtual reality

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

Over the last few years, virtual reality (VR) has emerged as a new technology that is allowing scientific research to investigate topics from another perspective. This is due to the possibility of creating more realistic scenarios in which all the variables are controlled. Thus, the conclusions taken from such research are more consistent since the […]

Pan: Impact of Geometry Reduction on Room Acoustic Simulation

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

Conventional acoustic simulations are based on CAD models. The creation of the 3D model requires modeling expertise and time. Additionally, the variety of model strategies makes this process difficult to reproduce. In contrast, Photogrammetry techniques can economically achieve valid representations of rooms. However, the models created using Photogrammetry are aimed at visualization purposes. The models […]

Fatela: Interpolation of scheduled simulation results for auralization.

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

Auralization is a technique which allows the rendering of realistic 3D audio based on virtual spatial scenes. Certain sound propagation parameters (or so-called auralization parameters) such as propagation delay, atmospheric attenuation, and spreading loss, can be derived from physics-based simulations of virtual scenes. These parameters are essential to rendering plausible sound signals in a spatial […]
