TY - THES A1 - Rosenthal, Fabian T1 - Einsatz und Anpassung von Methoden der Audio-Feature-Extraktion am Beispiel von Indoor Soundscapes N2 - Im häuslichen Umfeld erleben Menschen abhängig von ihrer Wohnsituation unterschiedlichste Geräuschumgebungen (Indoor Soundscapes), die einen hohen Einfluss auf das Wohlbefinden haben. Im Rahmen einer Feldstudie wurde daher die theoretisch und praktisch relevante Frage untersucht, welche Merkmale der wahrgenommenen Geräuschumgebungen als besonders ereignisreich oder angenehm bewertet werden. Einhundertfünf Teilnehmer*innen berichteten nach der Experience-Sampling-Methode zeitgesteuert über auftretende Geräuschumgebungen des häuslichen Alltags. Sie bewerteten deren subjektive Wirkung gemäß Soundscape-Standard. Zudem fertigten sie in-situ Audioaufnahmen der Geräuschszenarien an. Die 6594 Tonaufnahmen wurden einer Audioinhaltsanalyse unterzogen und im Zuge dessen wurden vier Featuresets verschiedener Berechnungsansätze extrahiert. Mithilfe der Perzentilen LASSO-Regularisierung wurden lineare gemischte Modelle für Angenehmheit und Ereignisreichtum sowie drei Multilevel-Modelle für Angenehmheit aufgestellt. Die besten Modelle erklären 9 % der Varianz von Angenehmheit und 27 % der Varianz von Ereignisreichtum durch feste Effekte selektierter Prädiktoren aller getesteten Featuresets. Angenehmheit sinkt vor allem, wenn lautheitsbasierte Features hohe Werte zeigen. Ereignisreichtum ist am stärksten abhängig von kurzen Spitzen des C-bewerteten Schalldruckpegels und wird im Vergleich zu Angenehmheit stärker von Zeitschwankungen der Features bestimmt. Durch den Vergleich der Featuresets wird deutlich, dass die Modelleffekte bekannter psychoakustischer Größen durch Hinzufügen von MFCC-Features verbessert werden. Darüber hinaus wird anhand von Multilevel-Modellen gezeigt, dass die Angenehmheit des lautesten Viertels der Tonaufnahmen deutlich besser durch feste Effekte erklärbar ist als der leisere Rest des Datensatzes. Kongruent mit aktuellen Befragungsstudien kann durch Audiofeatures eine Kategorienabhängigkeit der Soundscape-Bewertungen belegt werden: Musik und Sprache werden als angenehmer bewertet, technische Geräusche und Anlagenrauschen hingegen als unangenehmer. Hoher Ereignisreichtum hängt mit menschgemachten Geräuschen (z. B. Poltern, Stuhlrücken) zusammen. Diese Ergebnisse stellen eine wichtige Komponente in der umfassenden Beschreibung komplexer Geräuschumgebungen dar und ihnen kommt in Zeiten der SARS-CoV-2-Pandemie, in denen Wohnraum vermehrt heterogen genutzt werden muss, eine erhöhte Bedeutung zu. N2 - Depending on their living situation, people experience a wide variety of indoor soundscapes in their home environment, which have a major impact on their well-being. As part of a field study, the theoretically and practically relevant question of which features of the perceived soundscapes are rated as particularly eventful or pleasant was therefore investigated. One hundred and five participants used the experience sampling method to report on noise environments that occur in everyday domestic life. They assessed their subjective impact according to the soundscape standard. They also made in-situ audio recordings of the sound scenarios. The 6594 sound recordings were subjected to an audio content analysis and four feature sets of different calculation approaches were extracted. Using percentile LASSO regularisation, linear mixed models for pleasantness and event richness and three multilevel models for pleasantness were constructed. The best models explain 9 % of the variance of pleasantness and 27 % of the variance of event richness by fixed effects of selected predictors of all tested feature sets. Pleasantness decreases especially when loudness-based features show high values. Event richness is most dependent on short peaks of the C-weighted sound pressure level and is more strongly determined by time variations of the features compared to pleasantness. By comparing the feature sets, it becomes clear that the modelling effects of known psychoacoustic quantities are improved by adding MFCC features. In addition, multilevel models show that the pleasantness of the loudest quarter of the sound recordings can be explained much better by fixed effects than the quieter rest of the data set. Congruent with current survey studies, a category dependency of the soundscape evaluations can be proven by audio features: Music and speech are rated as more pleasant, while technical noises and system noise are rated as more unpleasant. High event richness is related to man-made noises (e.g. rumbling, chair backs). These results represent an important component in the comprehensive description of complex noise environments and they are of increased importance in times of the SARS-CoV-2 pandemic, when living space must be used increasingly heterogeneously.

The PSFC controls an entire sound field, including sound direction, virtual distance, and simulated environment (reverb level, room size and liveness) for each source. It can also configure a dry (DSP-less) switching matrix for direct directionalization.

Symp. on Simulation, Visualization and Auralization for Acoustic Research and Education N2 - In a virtual reality environment users are immersed in a scene with objects which might produce sound. The responsibility of a VR environment is to present these objects, but a system has only limited resources, including spatialization channels (mixels), MIDI/audio channels, and processing power. The sound spatialization resource manager controls sound resources and optimizes fidelity (presence) under given conditions. For that a priority scheme based on human psychophysical hearing is needed. Parameters for spatialization priorities include intensity calculated from volume and distance, orientation in the case of non-uniform radiation patterns, occluding objects, frequency spectrum (low frequencies are harder to localize), expected activity, and others. Objects which are spatially close together (depending on distance and direction) can be mixed. Sources that can not be spatialized can be treated as a single ambient sound source. Important for resource management is the resource assignment, i.e., minimizing swap operations, which makes it desirable to look-ahead and predict upcoming events in a scene. Prediction is achieved by monitoring objects’ speed and past evaluation values. Fidelity is contrasted for Zifferent kind of resource restrictions and optimal resource assignment based upon unlimited dynamic scene look-ahead. To give standard and comparable results, the VRML 2.0 specification is used as an application programmer interface. Applicability is demonstrated with a helical keyboard, a polyphonic MIDI stream driven animation including user interaction (user moves around, playing together with programmed notes). The developed sound spatialization resource manager gives improved spatialization fidelity under runtime constraints. Application programmers and virtual reality scene designers are freed from the burden of assigning and predicting the sound sources.

The PSFC features realtime manipulation of the primary components of sound spatialization for each of two audio sources located in a virtual environment, including the content (apparent direction and distance) and context (room characteristics: reverberation level, room size and liveness). In an alternate mode, it can also direct the destination of the two separate input signals across 14 loudspeakers, manipulating the direction of the virtual sound sources with no control over apparent distance other than that afforded by source loudness (including no simulated environmental reflections or reverberation). The PSFC speaker dome is about 10 m in diameter, accommodating about fifty simultaneous users, including about twenty users comfortably standing or sitting near its ``sweet spot,'' the area in which the illusions of sound spatialization are most vivid. Collocated with a large screen rear-projection stereographic display, the PSFC is intended for advanced multimedia and virtual reality applications.
