12:40	An Introduction to MPEG-H 3D Audio Simone Füg, Achim Kuntz [Abstract] Using a binaural-listening paradigm age-related differences in the ability to intentionally switch auditory selective attention were examined. A number of 20 young, normal- hearing subjects and 20 elderly, moderately hearing- impaired subjects were tested under anechoic room conditions. The non-individual spatial reproduction of stimuli was provided by open headphones using HRTFs of an artificial head. Spoken digits of two speakers were presented simultaneously to subjects from two out of eight different locations on the horizontal plane. Guided by a visual cue, subjects were asked to categorize the target’s digit into smaller vs. greater than five while ignoring the distractor’s speech. Results showed significantly greater reaction times and error rates for elderly subjects. The influence of the spatial transition of the target-speaker (switch or repetition of speaker’s direction in space) was identical across age groups. However, it was generally somewhat easier for younger people to filter out the distractor’s speech, indicating age-related difficulties to focus on a single speaker and ignore others.

Guided by a visual cue, subjects were asked to categorize the target’s digit into smaller vs. greater than five while ignoring the distractor’s speech. Results showed significantly greater reaction times and error rates for elderly subjects. The influence of the spatial transition of the target-speaker (switch or repetition of speaker’s direction in space) was identical across age groups. However, it was generally somewhat easier for younger people to filter out the distractor’s speech, indicating age-related difficulties to focus on a single speaker and ignore others.

Spoken digits of two speakers were presented simultaneously to subjects from two out of eight different locations on the horizontal plane. Guided by a visual cue, subjects were asked to categorize the target’s digit into smaller vs. greater than five while ignoring the distractor’s speech. Results showed significantly greater reaction times and error rates for elderly subjects. The influence of the spatial transition of the target-speaker (switch or repetition of speaker’s direction in space) was identical across age groups. However, it was generally somewhat easier for younger people to filter out the distractor’s speech, indicating age-related difficulties to focus on a single speaker and ignore others.

The influence of the spatial transition of the target-speaker (switch or repetition of speaker’s direction in space) was identical across age groups. However, it was generally somewhat easier for younger people to filter out the distractor’s speech, indicating age-related difficulties to focus on a single speaker and ignore others.
15:20	Simulation der Schallabstrahlung großer Strukturen mit Hilfe von hierarchischen Matrizen Boris Dilba, Otto von Estorff, Olgierd Zaleski [Abstract] Using a binaural-listening paradigm age-related differences in the ability to intentionally switch auditory selective attention were examined. A number of 20 young, normal- hearing subjects and 20 elderly, moderately hearing- impaired subjects were tested under anechoic room conditions. The non-individual spatial reproduction of stimuli was provided by open headphones using HRTFs of an artificial head. Spoken digits of two speakers were presented simultaneously to subjects from two out of eight different locations on the horizontal plane. Guided by a visual cue, subjects were asked to categorize the target’s digit into smaller vs. greater than five while ignoring the distractor’s speech. Results showed significantly greater reaction times and error rates for elderly subjects. The influence of the spatial transition of the target-speaker (switch or repetition of speaker’s direction in space) was identical across age groups.

A number of 20 young, normal- hearing subjects and 20 elderly, moderately hearing- impaired subjects were tested under anechoic room conditions. The non-individual spatial reproduction of stimuli was provided by open headphones using HRTFs of an artificial head. Spoken digits of two speakers were presented simultaneously to subjects from two out of eight different locations on the horizontal plane. Guided by a visual cue, subjects were asked to categorize the target’s digit into smaller vs. greater than five while ignoring the distractor’s speech. Results showed significantly greater reaction times and error rates for elderly subjects. The influence of the spatial transition of the target-speaker (switch or repetition of speaker’s direction in space) was identical across age groups. However, it was generally somewhat easier for younger people to filter out the distractor’s speech, indicating age-related difficulties to focus on a single speaker and ignore others.

Results showed significantly greater reaction times and error rates for elderly subjects. The influence of the spatial transition of the target-speaker (switch or repetition of speaker’s direction in space) was identical across age groups. However, it was generally somewhat easier for younger people to filter out the distractor’s speech, indicating age-related difficulties to focus on a single speaker and ignore others.

Guided by a visual cue, subjects were asked to categorize the target’s digit into smaller vs. greater than five while ignoring the distractor’s speech. Results showed significantly greater reaction times and error rates for elderly subjects. The influence of the spatial transition of the target-speaker (switch or repetition of speaker’s direction in space) was identical across age groups. However, it was generally somewhat easier for younger people to filter out the distractor’s speech, indicating age-related difficulties to focus on a single speaker and ignore others.

The non-individual spatial reproduction of stimuli was provided by open headphones using HRTFs of an artificial head. Spoken digits of two speakers were presented simultaneously to subjects from two out of eight different locations on the horizontal plane. Guided by a visual cue, subjects were asked to categorize the target’s digit into smaller vs. greater than five while ignoring the distractor’s speech. Results showed significantly greater reaction times and error rates for elderly subjects. The influence of the spatial transition of the target-speaker (switch or repetition of speaker’s direction in space) was identical across age groups. However, it was generally somewhat easier for younger people to filter out the distractor’s speech, indicating age-related difficulties to focus on a single speaker and ignore others.

14:00	Möglichkeiten und Konzepte zur Lärmminderung im Luftverkehr Helmut Breidenbach, Berthold Fuld [Abstract] Using a binaural-listening paradigm age-related differences in the ability to intentionally switch auditory selective attention were examined. A number of 20 young, normal- hearing subjects and 20 elderly, moderately hearing- impaired subjects were tested under anechoic room conditions. The non-individual spatial reproduction of stimuli was provided by open headphones using HRTFs of an artificial head. Spoken digits of two speakers were presented simultaneously to subjects from two out of eight different locations on the horizontal plane. Guided by a visual cue, subjects were asked to categorize the target’s digit into smaller vs. greater than five while ignoring the distractor’s speech. Results showed significantly greater reaction times and error rates for elderly subjects. The influence of the spatial transition of the target-speaker (switch or repetition of speaker’s direction in space) was identical across age groups. However, it was generally somewhat easier for younger people to filter out the distractor’s speech, indicating age-related difficulties to focus on a single speaker and ignore others.

17:20	Appilcation of DIN SPEC 40170 for the evaluation of ultrasonic devices used in hospitals and dental practises for cleaning of surgical instruments Anna Seibold, Andreas Richter [Abstract] Using a binaural-listening paradigm age-related differences in the ability to intentionally switch auditory selective attention were examined. A number of 20 young, normal- hearing subjects and 20 elderly, moderately hearing- impaired subjects were tested under anechoic room conditions. The non-individual spatial reproduction of stimuli was provided by open headphones using HRTFs of an artificial head. Spoken digits of two speakers were presented simultaneously to subjects from two out of eight different locations on the horizontal plane. Guided by a visual cue, subjects were asked to categorize the target’s digit into smaller vs. greater than five while ignoring the distractor’s speech. Results showed significantly greater reaction times and error rates for elderly subjects. The influence of the spatial transition of the target-speaker (switch or repetition of speaker’s direction in space) was identical across age groups. However, it was generally somewhat easier for younger people to filter out the distractor’s speech, indicating age-related difficulties to focus on a single speaker and ignore others.

The influence of the spatial transition of the target-speaker (switch or repetition of speaker’s direction in space) was identical across age groups. However, it was generally somewhat easier for younger people to filter out the distractor’s speech, indicating age-related difficulties to focus on a single speaker and ignore others.
10:22	Individualized and noise-adaptive enhancement of speech intelligibility Aleksandra Kubiak, Jan Rennies, Andreas Volgenandt, Jakob Drefs, Birger Kollmeier [Abstract] Using a binaural-listening paradigm age-related differences in the ability to intentionally switch auditory selective attention were examined. A number of 20 young, normal- hearing subjects and 20 elderly, moderately hearing- impaired subjects were tested under anechoic room conditions. The non-individual spatial reproduction of stimuli was provided by open headphones using HRTFs of an artificial head. Spoken digits of two speakers were presented simultaneously to subjects from two out of eight different locations on the horizontal plane. Guided by a visual cue, subjects were asked to categorize the target’s digit into smaller vs. greater than five while ignoring the distractor’s speech. Results showed significantly greater reaction times and error rates for elderly subjects. The influence of the spatial transition of the target-speaker (switch or repetition of speaker’s direction in space) was identical across age groups. However, it was generally somewhat easier for younger people to filter out the distractor’s speech, indicating age-related difficulties to focus on a single speaker and ignore others.

Guided by a visual cue, subjects were asked to categorize the target’s digit into smaller vs. greater than five while ignoring the distractor’s speech. Results showed significantly greater reaction times and error rates for elderly subjects. The influence of the spatial transition of the target-speaker (switch or repetition of speaker’s direction in space) was identical across age groups. However, it was generally somewhat easier for younger people to filter out the distractor’s speech, indicating age-related difficulties to focus on a single speaker and ignore others.

Guided by a visual cue, subjects were asked to categorize the target’s digit into smaller vs. greater than five while ignoring the distractor’s speech. Results showed significantly greater reaction times and error rates for elderly subjects. The influence of the spatial transition of the target-speaker (switch or repetition of speaker’s direction in space) was identical across age groups. However, it was generally somewhat easier for younger people to filter out the distractor’s speech, indicating age-related difficulties to focus on a single speaker and ignore others.

Guided by a visual cue, subjects were asked to categorize the target’s digit into smaller vs. greater than five while ignoring the distractor’s speech. Results showed significantly greater reaction times and error rates for elderly subjects. The influence of the spatial transition of the target-speaker (switch or repetition of speaker’s direction in space) was identical across age groups. However, it was generally somewhat easier for younger people to filter out the distractor’s speech, indicating age-related difficulties to focus on a single speaker and ignore others.

15:20	Expositionsdauer und Labeling beeinflussen die subjektive Bewertung von Maskierschall für Bürolärm Sabine Schlittmeier [Abstract] Using a binaural-listening paradigm age-related differences in the ability to intentionally switch auditory selective attention were examined. A number of 20 young, normal- hearing subjects and 20 elderly, moderately hearing- impaired subjects were tested under anechoic room conditions. The non-individual spatial reproduction of stimuli was provided by open headphones using HRTFs of an artificial head. Spoken digits of two speakers were presented simultaneously to subjects from two out of eight different locations on the horizontal plane. Guided by a visual cue, subjects were asked to categorize the target’s digit into smaller vs. greater than five while ignoring the distractor’s speech. Results showed significantly greater reaction times and error rates for elderly subjects. The influence of the spatial transition of the target-speaker (switch or repetition of speaker’s direction in space) was identical across age groups. However, it was generally somewhat easier for younger people to filter out the distractor’s speech, indicating age-related difficulties to focus on a single speaker and ignore others.

Guided by a visual cue, subjects were asked to categorize the target’s digit into smaller vs. greater than five while ignoring the distractor’s speech. Results showed significantly greater reaction times and error rates for elderly subjects. The influence of the spatial transition of the target-speaker (switch or repetition of speaker’s direction in space) was identical across age groups. However, it was generally somewhat easier for younger people to filter out the distractor’s speech, indicating age-related difficulties to focus on a single speaker and ignore others.

The non-individual spatial reproduction of stimuli was provided by open headphones using HRTFs of an artificial head. Spoken digits of two speakers were presented simultaneously to subjects from two out of eight different locations on the horizontal plane. Guided by a visual cue, subjects were asked to categorize the target’s digit into smaller vs. greater than five while ignoring the distractor’s speech. Results showed significantly greater reaction times and error rates for elderly subjects. The influence of the spatial transition of the target-speaker (switch or repetition of speaker’s direction in space) was identical across age groups. However, it was generally somewhat easier for younger people to filter out the distractor’s speech, indicating age-related difficulties to focus on a single speaker and ignore others.
