The present field study therefore investigated whether sound pressure level, reverberation time, and soundscape pleasantness can predict factors associated with overall restaurant quality. In total, 142 persons visiting 12 restaurants in Berlin rated relevant acoustical and non-acoustical factors associated with restaurant quality. Simultaneously, the A-weighted sound pressure level (LA,eq,15) was measured, and the reverberation time in the occupied state (T20,occ) was obtained by measurements performed in the unoccupied room and a subsequent calculation of the occupied condition according to DIN 18041. Results from linear mixed-effects models revealed that both the LA,eq,15 and T20,occ had a significant influence on soundscape pleasantness and eventfulness, whereby the effect of T20,occ was meditated by the LA,eq,15. Also, the LA,eq,15 as well as soundscape pleasantness were significant predictors of overall restaurant quality. A comprehensive structural equation model including both acoustical and non-acoustical factors, however, indicates that the effect of soundscape pleasantness on overall restaurant quality is mediated by the restaurant's atmosphere. Our results support and extend previous findings which suggest that the acoustical design of restaurants involves a trade-off between comfort and liveliness, depending on the desired character of the place.}, language = {en} } @misc{VersuemerSteffensRosenthal2023, author = {Vers{\"u}mer, Siegbert and Steffens, Jochen and Rosenthal, Fabian}, title = {Extensive crowdsourced dataset of in-situ evaluated binaural soundscapes of private dwellings containing subjective sound-related and situational ratings along with person factors to study time-varying influences on sound perception - research data}, edition = {V.01.1}, address = {Zenodo}, doi = {10.5281/zenodo.7193937}, year = {2023}, abstract = {The soundscape approach highlights the role of situational factors in sound evaluations; however, only a few studies have applied a multi-domain approach including sound-related, person-related, and time-varying situational variables. Therefore, we conducted a study based on the Experience Sampling Method to measure the relative contribution of a broad range of potentially relevant acoustic and non-auditory variables in predicting indoor soundscape evaluations. Here we present the comprehensive dataset for which 105 participants reported temporally (rather) stable trait variables such as noise sensitivity, trait affect, and quality of life. They rated 6.594 situations regarding the soundscape standard dimensions, perceived loudness, and the saliency of its sound components and evaluated situational variables such as state affect, perceived control, activity, and location. To complement these subject-centered data, we additionally crowdsourced object-centered data by having participants make binaural measurements of each indoor soundscape at their homes using a low-(self-)noise recorder. These recordings were used to compute (psycho-)acoustical indices such as the energetically averaged loudness level, the A-weighted energetically averaged equivalent continuous sound pressure level, and the A-weighted five-percent exceedance level. This complex hierarchical data can be used to investigate time-varying non-auditory influences on sound perception and to develop soundscape indicators based on the binaural recordings to predict soundscape evaluations.}, subject = {soundscape}, language = {en} } @masterthesis{Rosenthal2022, type = {Bachelor Thesis}, author = {Rosenthal, Fabian}, title = {Einsatz und Anpassung von Methoden der Audio-Feature-Extraktion am Beispiel von Indoor Soundscapes}, address = {D{\"u}sseldorf}, organization = {Hochschule D{\"u}sseldorf}, doi = {10.20385/opus4-4399}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-43991}, school = {Hochschule D{\"u}sseldorf}, pages = {77}, year = {2022}, abstract = {Im h{\"a}uslichen Umfeld erleben Menschen abh{\"a}ngig von ihrer Wohnsituation unterschiedlichste Ger{\"a}uschumgebungen (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 Ger{\"a}uschumgebungen als besonders ereignisreich oder angenehm bewertet werden. Einhundertf{\"u}nf Teilnehmer*innen berichteten nach der Experience-Sampling-Methode zeitgesteuert {\"u}ber auftretende Ger{\"a}uschumgebungen des h{\"a}uslichen Alltags. Sie bewerteten deren subjektive Wirkung gem{\"a}ß Soundscape-Standard. Zudem fertigten sie in-situ Audioaufnahmen der Ger{\"a}uschszenarien an. Die 6594 Tonaufnahmen wurden einer Audioinhaltsanalyse unterzogen und im Zuge dessen wurden vier Featuresets verschiedener Berechnungsans{\"a}tze extrahiert. Mithilfe der Perzentilen LASSO-Regularisierung wurden lineare gemischte Modelle f{\"u}r Angenehmheit und Ereignisreichtum sowie drei Multilevel-Modelle f{\"u}r Angenehmheit aufgestellt. Die besten Modelle erkl{\"a}ren 9 \% der Varianz von Angenehmheit und 27 \% der Varianz von Ereignisreichtum durch feste Effekte selektierter Pr{\"a}diktoren aller getesteten Featuresets. Angenehmheit sinkt vor allem, wenn lautheitsbasierte Features hohe Werte zeigen. Ereignisreichtum ist am st{\"a}rksten abh{\"a}ngig von kurzen Spitzen des C-bewerteten Schalldruckpegels und wird im Vergleich zu Angenehmheit st{\"a}rker von Zeitschwankungen der Features bestimmt. Durch den Vergleich der Featuresets wird deutlich, dass die Modelleffekte bekannter psychoakustischer Gr{\"o}ßen durch Hinzuf{\"u}gen von MFCC-Features verbessert werden. Dar{\"u}ber hinaus wird anhand von Multilevel-Modellen gezeigt, dass die Angenehmheit des lautesten Viertels der Tonaufnahmen deutlich besser durch feste Effekte erkl{\"a}rbar ist als der leisere Rest des Datensatzes. Kongruent mit aktuellen Befragungsstudien kann durch Audiofeatures eine Kategorienabh{\"a}ngigkeit der Soundscape-Bewertungen belegt werden: Musik und Sprache werden als angenehmer bewertet, technische Ger{\"a}usche und Anlagenrauschen hingegen als unangenehmer. Hoher Ereignisreichtum h{\"a}ngt mit menschgemachten Ger{\"a}uschen (z. B. Poltern, Stuhlr{\"u}cken) zusammen.

Although research programmes in psychology and economics have contributed to an improved understanding of music-related behaviour, historically, these disciplines have been unconnected. Recently, however, researchers have begun to bridge this gap by employing tools from behavioural economics. This article contributes to the literature by providing a discussion about the benefits of using behavioural economics in music-decision research. We achieve this in two ways. First, through a systematic review, we identify the current state of the literature within four key areas of behavioural economics-heuristics and biases, social decision-making, behavioural time preferences, and dual-process theory. Second, taking findings of the literature as a starting point, we demonstrate how behavioural economics can inform future research. Based on this, we propose the Behavioural Economics of Music (BEM), an integrated research programme that aims to break new ground by stimulating interdisciplinary research in the intersection between music, psychology, and economics.}, language = {en} } @inproceedings{BrettschneiderHerderdeMooijetal.2019, author = {Brettschneider, Nico and Herder, Jens and de Mooij, Jeroen and Ryskeldiev, Bektur}, title = {Audio vs. Visual Avatars as Guides in Virtual Environments}, series = {21th International Conference on Human and Computer, HC-2018, March 27-28, 2019, Shizuoka University, Hamamatsu, Japan.}, booktitle = {21th International Conference on Human and Computer, HC-2018, March 27-28, 2019, Shizuoka University, Hamamatsu, Japan.}, editor = {Herder, Jens}, publisher = {Hochschule D{\"u}sseldorf}, address = {D{\"u}sseldorf}, organization = {Hochschule D{\"u}sseldorf}, doi = {10.20385/0hrj-qc02}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-23859}, pages = {9}, year = {2019}, abstract = {Through constant technical progress, multi-user virtual reality is transforming towards a social activity that is no longer only used by remote users, but also in large-scale location-based experiences. We evaluate the usage of realtime-tracked avatars in co-located business-oriented applications in a "guide-user-scenario" in comparison to audio only instructions. The present study examined the effect of an avatar-guide on the user-related factors of Spatial Presence, Social Presence, User Experience and Task Load in order to propose design guidelines for co-located collaborative immersive virtual environments. Therefore, an application was developed and a user study with 40 participants was conducted in order to compare both guiding techniques of a realtime-tracked avatar guide and a non-visualised guide with otherwise constant conditions. Results reveal that the avatar-guide enhanced and stimulated communicative processes while facilitating interaction possibilities and creating a higher sense of mental immersion for users. Furthermore, the avatar-guide appeared to make the storyline more engaging and exciting while helping users adapt to the medium of virtual reality. Even though no assertion could be made concerning the Task Load factor, the avatar-guide achieved a higher subjective value on User Experience. Due to the results, avatars can be considered valuable social elements in the design of future co-located collaborative virtual environments.}, language = {en} }
