SUMMARY:Heras: Internship on Perceptual Evaluation of Consumer Spatial Audio Solutions over Headphones
DESCRIPTION:This presentation covers the internship in the Advanced Technology Team at Bang & Olufsen. The main task invoved a research project focusing on the perceptual evaluation of different spatial audio solutions that may be used for commercial headphones. This included a complete project starting with a review of existing literature\, existing technologies\, and evaluation methodologies. This was  followed by a methodology design and the subsequent implementation of a listening experiment using the software developed at B&O. Participants were recruited to collect perceptual data which was later analysed. The methodology was documented internally to ensure that such tests can be repeated in the future inside the company. As an active part of the Advanced Technology\, other duties included support to other research projects being carried out in the team as well. \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:He: Influence of (non) intelligible background noise on short-term memory and listening effort in conversational situations with running speech
DESCRIPTION:Background noise poses a significant challenge in daily conversations\, impacting short-term memory and listening effort. Existing studies often lack a realistic comparison between different types of background noise\, particularly between intelligible and unintelligible noise. In German-speaking contexts\, intelligible noise typically refers to recognizable German speech\, while unintelligible noise includes traffic sounds\, foreign languages\, or non-semantic sounds. Listening effort\, defined as the deliberate allocation of mental resources to overcome obstacles in achieving listening goals\, serves as a measure reflecting the cognitive load affecting short-term memory. This study investigates the effects of intelligible and unintelligible background noise on short-term memory and listening effort. A dual-task paradigm was employed\, with the Heard-Text Recall (HTR) task as the primary task to assess memory performance and a vibrotactile recognition task as the secondary task to measure listening effort. Results showed that background noise significantly increased listening effort and decreased short[1]term memory performance compared to silent conditions. However\, no significant differences were observed between intelligible and unintelligible noise regarding their impact on listening effort or memory performance. This may be attributed to the limited sample size. \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:Ke: Distraction due to moving sources in short-term memory tasks
DESCRIPTION:The irrelevant sound effect (ISE) is a popular topic in cognitive psychology\, referring to the phenomenon where hearing sounds unrelated to a memory task disrupts recall during task performance. Research on the ISE can deepen understanding of the human brain’s information processing mechanisms\, thereby making contributions to advancements in the medical field while also providing a foundation for optimizing educational and work environments. In this study\, in order to further investigate the ISE\, a verbal memory task and a spatial memory task were designed\, with four different background noise conditions introduced (i.e.\, no noise\, stationary noise\, continuous motion noise\, and discrete motion noise). The proportion of correct responses and response time were used as performance measures. The experimental results neither showed a significant effect of spatially changing background speech on spatial memory nor on verbal memory. This could be due to the limited sample size. \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:Roos: Influence of Ground Effects in Road Traffic Auralization
DESCRIPTION:It is broadly recognized that noise pollution is widespread\, especially in urban areas\, and can cause long-term psychological effects and health issues. Road traffic noise is a major contributor to noise pollution in residential areas and affects the well-being of a significant number of people. Auralization\, the process of making acoustic environments virtually audible through simulation\, can help urban planners predict the propagation of sound waves in complex urban environments and\, thus\, provide a deeper\, more intuitive insight into the acoustic environment. The propagation of outdoor sound is influenced by many factors\, including geometric spreading\, reflection and diffraction\, atmospheric absorption and meteorological conditions. Other wave propagation mechanisms\, called ground effects\, only occur near the ground\, where phenomena such as the attenuation of spherical waves\, as well as\, ground porosity and roughness have a significant influence on the phase and amplitude of the reflected sound field. However\, outdoor auralization models that are frequently based on geometrical acoustics\, do not yet adequately model these propagation mechanisms. This thesis aims at examining the influence of ground effects on road traffic noise and propose changes to an existing outdoor auralization model with the eventual goal of achieving more plausible road traffic auralization results. Along the way\, in-situ ground impedance measurements have been conducted with the aim of further improving predictions of outdoor sound propagation. \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:Sinarso: The Impact of Socio-Economic Background on Children's Speech Perception and Listening Effort
DESCRIPTION:It is frequently reported that children from different socioeconomic backgrounds perform differently in school. However\, the factors mediating the relationship between socioeconomic status (SES) and cognitive outcomes remain an ongoing topic of research. This study investigates the extent to which SES inequalities influence speech perception and listening effort\, two aspects that could be at the root of academic difficulties. Building on data from Seitz et al. [2024]\, who conducted a dual-task listening experiment under classroom-like noise conditions\, an SES index based on Factor Analysis of Mixed Data (FAMD) was used to categorize participants. This research focuses on children between the ages of six and ten\, with adults included for comparison. The analysis\, conducted using statistical modeling approaches\, reveals that under challenging noise conditions\, children from low-SES backgrounds made more errors. However\, they completed the listening tasks faster than their higher-SES peers. These children also perceived their effort as lower\, despite the increased difficulty indicated by performance metrics. Although limitations in the adult sample hindered drawing conclusions for this population\, differences in listening ability and effort in children were observed. These findings suggest SES-related differences in skills relevant for academic success\, which might serve as early markers of academic inequities. \nDE: \nEs wird häufig festgestellt\, dass Kinder aus unterschiedlichen sozioökonomischen Hintergründen in der Schule unterschiedlich abschneiden. Welche Faktoren jedoch die Beziehung zwischen sozioökonomischem Status (SES) und kognitiven Leistungen vermitteln\, ist weiterhin Gegenstand aktueller Forschung. Diese Arbeit untersucht\, inwiefern Ungleichheiten im SES die Sprachwahrnehmung und Höranstrengung beeinflussen. Letztere beiden Aspekte könnten als Ursache für schulische Schwierigkeiten in Betracht kommen. Diese Studie basiert auf den Daten von Seitz et al. [2024]\, die im Rahmen eines Dual-Task-Hörexperiments unter klassenzimmerähnlichen Geräuschbedingungen erhoben wurden. Auf dieser Grundlage erfolgte eine Kategorisierung der Teilnehmerinnen und Teilnehmer mithilfe eines SES-Index\, der auf der Methode der Faktoranalyse gemischter Daten (FAMD) basiert. Im Rahmen dieser Untersuchung wurden Kinder im Alter zwischen sechs und zehn Jahren untersucht\, wobei zudem Erwachsene als Vergleichsgruppe herangezogen wurden. Die Analyse mit statistischen Modellierungsansätzen zeigt\, dass Kinder aus niedrigem SES-Hintergrund unter herausfordernden Lärmbedingungen mehr Fehler machten. Gleichzeitig lösten sie die Höraufgaben schneller als ihre besser gestellten Altersgenossen. Diese Kinder schätzten auch ihre Anstrengung als geringer ein\, obwohl die Ergebnisse des Hörversuchs einen höheren Schwierigkeitsgrad andeuteten. Obwohl die Einschränkungen in der Erwachsenenstichprobe das Ziehen von Schlussfolgerungen für diese Population verhinderten\, wurden Unterschiede in der Hörfähigkeit und der Anstrengung bei Kindern beobachtet. Diese Ergebnisse deuten auf SES-bezogene Unterschiede in den für den schulischen Erfolg relevanten Fähigkeiten hin\, die als frühe Marker für schulische Ungleichheiten dienen könnten. \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:Denker: Industrial internship at Demant A/S
DESCRIPTION:Content of this presentation is a summary of my tasks and projects I contributed to during my six-months internship in the Centre for Applied Audiology Research (CAAR) for the Oticon brand at Demant A/S in Smørum\, Denmark. \nGenerally\, there are two kinds of projects the CAAR-Team is occupied with. Firstly\, the delivery of reliable and scientifically based claims used in global marketing and promotion derived through both clinical and technical studies on pre-released hearing aids. Secondly\, the development of research methods and scientific collaborations (including Bachelor or Master projects and PhD positions). \nDuring the internship I was involved in both kinds of projects. I contributed to the claims process by carrying out and following up on the technical study for the next release (25.1) of Oticon’s upgraded CIC/IIC (Completely-in-the-Canal/Invisible-in-the-Canal) hearing aids. On the development of research methods\, I was handed a project to investigate the possibility of including commonly conducted technical measures\, like output SNR measurements using the phase-inversion technique\, in clinical studies. \n  \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
