1st IHTA Retreat

05. Juni 2023 | von

An interchange for good teamwork between researchers
On 28th and 29th March 2023, the scientific staff of IHTA was on a retreat at Gut Hohenholz near Bedburg in the Rhein Erft Kreis. During these two days, the institute’s past was reflected, and it was discussed how the future of the IHTA can be shaped together. Moreover, there was an intensive exchange among each other’s scientific work in the form of poster sessions. The researchers presented each other’s projects and revealed which milestones needed to be reached to achieve specific goals. Between poster sessions team spirit was strengthened, and the future of teaching and workflows were addressed. Furthermore, it was discussed how the skills of individual researchers could be maintained and passed on to new staff members.

Overall, it was two successful days with a lot of input for each individual and a lot of output for the group at IHTA.
A big thank you to Joachim Bellut, who guided us through the two days with his great moderation!

Promotionsprüfung Josefa Oberem, M.Sc.

27. Januar 2020 | von

Am 24. Januar 2020 hat FrauJosefa Oberem, M.Sc, ihre mündliche Promotionsprüfung erfolgreich abgeschlossen.

Frau Oberem promovierte über das Thema:
„Examining auditory selective attention: From dichotic towards realistic environments“

Abstract:

The aim of the present thesis is to examine the cognitive control mechanisms underlying auditory selective attention by considering the influence of variables that increase the complexity of an auditory scene. Therefore, technical aspects such as dynamic binaural hearing, room acoustics and head movements as well as those that influence the efficiency of cognitive processing are taken into account. Step-wise a well-established dichotic-listening paradigm is extended into a “realistic” spatial listening paradigm.
Conducted empirical surveys are based on a dichotic-listening paradigm examining the intentional switching of auditory selective attention. Spoken phrases are simultaneously presented by two speakers to participants from two of eight azimuthal positions. The stimuli are phrases that consist of a single digit (1 to 9, excluding 5), in some experiments followed by either the German direction “UP” or “DOWN”. A visual cue indicates the target’s spatial position, prior to auditory stimulus onset. Afterwards, participants are asked to identify whether the target number is arithmetically smaller or greater than five and to categorize the direction. Reaction time and accuracy are performance measures. Differences of performance measures between the repetition of the target’s spatial position and the related switch (switch costs) describe the loss of efficiency associated with redirecting attention from one target’s location to another. To examine whether the irrelevant auditory information is decoded, interference in the processing of task-relevant and task-irrelevant information is created in the paradigm.
To study the binaural effects in the intentional switching of auditory selective attention, the dichotic-listening paradigm is gradually extended towards a binaural-listening paradigm representing complex dynamic acoustic scenes in the present thesis. In order to realize the extension of the paradigm towards a realistic scene various technical methods and tools need to be applied. As the listening paradigm is step-wise broadened towards realistic scenes the technical methods and tools are assessed with respect to the collected empirical results.
Using the binaural-listening paradigm, the ability to intentionally switch auditory selective attention is tested when applying different methods of spatial reproduction. Essential differences between real sources, an individual and a non-individual binaural synthesis reproduced with headphones as well as a binaural synthesis based on Cross-Talk Cancellation are found. This indicates how the loss of individual information reduces the ability to inhibit irrelevant information. Differences in performance measures occur also with regard to the target’s spatial position. Reliable findings on the spatial localization ability are confirmed applying the listening paradigm on the intentional switching of auditory selective attention. As a step towards multi-talker scenarios in realistic environments participants are tested in differently reverberating environments. Switch costs are highly affected by reverberation and the inhibition is also impaired by to be unattended information. Age-related effects are also found when applying the binaural-listening paradigm, indicating difficulties for elderly to suppress processing the distractor’s speech.

Das ITA gratuliert sehr herzlich!!
