Sani: Working with Multi Channel Audio: Setting up demos in SCaLAr

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

Working with 3D audio formats, especially Ambisonics, is not as straight-forward as traditional channel-based formats like stereo or 5.1. This gets even more complex with irregular loudspeaker arrays like SCaLAr: it is unlike any conventional speaker configuration, and therefore requires combinations of tools to achieve a relatively easy “drag and drop and play” situation.  I […]

Zhou: Short-term memory performance under varying signal-to-noise ratio

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

The term irrelevant sound effect (ISE) refers to a significant reduction in the immediate serial recall of lists of presented items, usually digits or letters, when irrelevant auditory sound is presented together with the items to be memorized. This study aimed to investigate the impact of signal-to-noise ratio (SNR) and presentation modality on short-term memory […]

These include raising awareness for the problem in the general public, extending the capabilities of hearing models used to predict psychoacoustic parameters, and designing […]

Jain: Text Mining of Vocabulary for Architectural and Acoustic Assessment

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

We often see a disconnect between how people express themselves through language and how those words are perceived or interpreted. This gap exists, for example, between architects who strive to meet client expectations and users of the designed spaces who express their needs and requirements. We aim to bridge this gap by investigating the vocabulary […]

Holländer: The influence of individual, individualized and non-individualized HRTFs on the auditory selective attention of children

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

A listening experiment based on a developed paradigm to investigate the intentional switching of auditory selective attention with binaural sound reproduction was conducted to examine the influence of generic, individualized and individual head-related transfer functions (HRTFs) on the auditory selective attention of children. For many applications, the generic HRTF of an adult artificial head is […]

Heinrichs: Schallstreuung an Straßenoberflächen

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

Für die möglichst präzise Auralisation von virtuellen Umgebungen ist die Kenntnis des genauen Schallfeldes der akustischen Szene notwendig. Einen Anteil zum diffusen Schall liefert dabei die Streuung an unebenen Oberflächen. In virtuellen Straßenumgebungen stellt daher die Streuung durch die Straßenoberfläche selbst einen möglichen Einfluss auf das Schallfeld dar. In der vorgestellten Arbeit werden die Schallstreuungseigenschaften […]

Angsuphanich: Development of a Paradigm to Examine Listening Comprehension in Virtual Reality

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

A previous study showed that background noises and background speech deteriorate children’s listening comprehension, as children lack the ability to neglect irrelevant sounds. A classroomlike atmosphere is required for an investigation of the effect of noise on listening comprehension. As a result, there is a possibility that certain uncontrollable elements will arise throughout the experiment. […]
