Metamaterials are an area of research that has its origins mainly in optics and electrical engineering, but has also been attracting growing interest in acoustics for several years. Basically, metamaterials are man-made structures whose properties differ from those of natural materials, for example, exhibiting features such as a negative mass or a negative refractive index. This enables new approaches for solving technological challenges in the field of acoustics and vibroacoustics.
The structured session »Acoustic Metamaterials« will feature contributions on current results from research and Industry. Aim is to not only address various areas of application, but also regarding the design process, practical implementation and feasibility for industrial application of acoustic metamaterials.

The session highlights new approaches for the development of smart hearing devices as an integral component in the communication loop between the user and the environment. We expect presentations dealing with identification and classification of sources and acoustic spaces, with models for control and processing in hearing devices, and presentations about laboratory experiments with hearing-assisted humans in the communication loop.

Eine neue Klasse von Augmented (AR) und Mixed Reality (MR) Devices beginnt sich auf dem Markt zu etablieren, die Head Mounted Displays mit extra-auraler Wiedergabe ebenso wie geschlossene Kopfhörer mit Hear-through Funktion einschließt. Während in der Akustik inzwischen gut erforscht ist, wie virtuelle Realitäten erzeugt werden können, ist kaum erforscht, welche Anforderungen an das Design und die Implementierung akustischer Szenen bestehen, die sich mit einer realen akustischen Umgebung plausibel überlagern sollen. Dies betrifft die Technologien der augmentierten Wiedergabe, die Darstellung der akustischen Quellen, die audio-visuelle Integration von realen und virtuellen Inhalten sowie die akustische Interaktion mit der räumlichen Umgebung ebenso wie die räumliche Wahrnehmung von AR/MR-Szenerien.

Acoustic holograms are finding growing interest in diverse fields ranging from particle trapping, to fabrication, to neurostimulation. This session will highlight recently developed and emerging methods to control sound fields using acoustic holograms, as well as new applications of acoustic holograms. Of particular interest are methods focusing on dynamic holograms, volume holograms, production of 3D fields, generation of trapping beams, as well as methods for rapidly characterizing complex acoustic fields produced by holograms. Example applications of interest could include particle manipulation, acoustic fabrication and assembly, or stimulation of biological or chemical systems. Presentations describing new applications or experimental and / or numerical methods relating to acoustic holograms are welcome.

Session topic: Motion and eye-gaze behavior during listening scenarios in real and virtual environments

Organized by: Christoph Reuter

In den letzten Jahren haben sich gleich aus mehreren Perspektiven spannende und das Fach bereichernde Möglichkeiten für die Forschung und Lehre in der musikalischen Akustik eröffnet. Seien es immer erschwinglichere Geräte wie 3D-Objekt/Raum-Scanner, Eye-Tracker, markerloses Motion Capture/Pose-Tracking, Biodatenlogger, Akustische Kameras etc., die die Datenerhebung von Musiker*innen und Instrumenten um viele Facetten bereichern, oder seien es neue Möglichkeiten, die Machine Learning Tools (Stichwort "TensorFlow"), Libraries wie Essentia, Librosa oder Script-Dialekte wie P5/P5.sound, Plotly etc. für die Klanganalyse und Visualisierung zur Verfügung stellen. Beiträge zu diesen und anderen zukunftsweisenden digitalen Entwicklungen für unser Fach sind in dieser strukturierten Session besonders willkommen.

How much music can a city take? Working towards a new approach to musical sound conflicts
The New Leipzig Charter propagates the lively city with mixed-use urban quarters in which, among other things, the cultural industry should also find and use its spaces. Music clubs make a significant contribution to the quality of life and attractiveness of cities and communities, especially for young people. But how can sound-intensive uses still be realized in the future if the neighborhood's need for quiet and its complaints become more pronounced and musical places for encounters are displaced as a result? A plea for an intensified exchange between the worlds of noise control and acoustics, urban planning, administration, politics and culture.

The development of computational methods for analyzing, segmenting, and classifying audio signals is of fundamental importance. As in general multimedia processing, many recent advances in audio processing (including speech, music, and environmental sounds) have been driven by deep learning (DL). In contrast to traditional audio engineering approaches, which directly exploit domain knowledge in the processing pipeline, DL-based approaches attempt to learn relevant patterns from (suitably annotated and structured) training data. In this session, we want to explore the benefits and limitations of model-based and data-driven techniques for learning task-specific sound event representations. Furthermore, we want to discuss explainable DL models that can better understand sound events' structural and acoustic properties. This session invites contributions that particularly address the following topics:

* Music information retrieval (e.g., structure analysis, instrument recognition, music transcription)
* Acoustic scene classification
* Separation, detection, and localization of sound events
* Integration of domain knowledge
* Hybrid approaches for audio signal processing
* Explainable and interpretable models
* Hierarchical classification approaches

Machine-learning (ML) based approaches to speech and speaker processing promise ever-improving performance for many tasks. As many of the corresponding models are trained for general purposes on large databases, they might discriminate against individual user groups with particular characteristics, such as impaired speech production, accentuated speech, or speaking in acoustically extreme environments. In addition, the built models may unveil sensitive information like the identity of speakers they are trained with, potentially causing privacy threats. At the same time, ML-based approaches might provide new tools dedicated for such user groups, helping to identify and overcome the obstacles.

It is the aim of this special session to present approaches of ML-based speech processing for medical and social good. Contributions may address (but are not limited to) the analysis and identification of impaired speech production and other speaker characteristics, the consideration of privacy by anonymizing speech, or by making models unaware of speaker identity, as well as the use of speech technology for assisting disfavored user groups. Particularly welcome are examples of how such approaches work in practice.

With the expansion of renewable energies, the distance between people and energy generators/converters is decreasing.  At the same time, the energy generating/converting systems are often perceived as disturbing noise sources and thus lose acceptance among the population. An analysis of the flow-acoustic sound sources offers the potential to reduce the sound radiation of energy systems such as wind turbines, heat pumps and ventilation systems and thus to achieve an increased acceptance in society.

Mit fortschreitender Entwicklung im Bereich der AR und VR nimmt der Einsatz von virtuellen Musikinstrumenten, deren virtuelle Synthese (z.B. via Physical Modeling, Sampling), deren Einbettung in virtuelle Umgebungen und/oder der Einsatz von 3D-Scannern, Photogrammetrie, Produktfotografie etc. zur Virtualisierung von einzelnen Instrumenten oder ganzen Sammlungen eine immer größere Bedeutung ein. In der strukturierten Sitzung zur Virtualisierung von Musikinstrumenten werden diese und andere damit zusammenhängende Themengebiete im Vordergrund stehen.
