These parameters intend to represent perceptual qualities, but were developed without a consistent modeling of room acoustical perception. More recent research proposed comprehensive inventories of room acoustic perception that are purely based on evaluations by human subjects, such as the Room Acoustical Quality Index (RAQI). In this work RA-QI scores acquired for 70 room impulse responses were predicted from room acoustical parameters. Except for Reverberance, the prediction of RAQI factors performed rather poor. In most cases, the sound source had a greater impact on RAQI scores. All analyses are published in an online tool, where users can upload omnidirectional and binaural impulse responses, and instantly obtain and visualize several physical descriptors, as well as predicted RAQI scores for three different sound sources. So far, acceptable prediction accuracy is achieved for Reverberance, Strength, Irregular Decay, Clarity and Intimacy. Larger data sets of evaluated impulse responses are required to improve the model performance and enable reliable predictions of room acoustical quality. Therefore, the administration of RAQI evaluations within the website is currently being developed.}, language = {en} } @article{SchreiberStruminksi2018, author = {Schreiber, Andreas and Struminksi, Regina}, title = {Visualizing the Provenance of Personal Data Using Comics}, series = {Computers}, volume = {7}, journal = {Computers}, number = {1}, publisher = {MDPI}, issn = {2073-431X}, doi = {10.3390/computers7010012}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-40286}, year = {2018}, language = {en} } @article{SteffensWilczekWeinzierl2021, author = {Steffens, Jochen and Wilczek, Tobias and Weinzierl, Stefan}, title = {Junk Food or Haute Cuisine to the Ear? - Investigating the Relationship Between Room Acoustics, Soundscape, Non-Acoustical Factors, and the Perceived Quality of Restaurants}, series = {Frontiers in Built Environment}, volume = {676009}, journal = {Frontiers in Built Environment}, publisher = {Frontiers}, issn = {2297-3362}, doi = {10.3389/fbuil.2021.676009}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-32115}, pages = {11}, year = {2021}, abstract = {Sound and music are well-studied aspects of the quality of experience in restaurants; the role of the room acoustical conditions, their influence on the visitors' soundscape evaluation and their impact on the overall customer satisfaction in restaurants, however, has received less scientific attention. 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} } @article{HaberfehlnervandeVenvanderBurgetal.2023, author = {Haberfehlner, Helga and van de Ven, Shankara S. and van der Burg, Sven A. and Huber, Florian and Georgievska, Sonja and Aleo, Ignazio and Harlaar, Jaap and Bonouvri{\´e}, Laura A. and van der Krogt, Marjolein M. and Buizer, Annemieke I.}, title = {Towards automated video-based assessment of dystonia in dyskinetic cerebral palsy: A novel approach using markerless motion tracking and machine learning}, series = {Frontiers in Robotics and AI}, volume = {10}, journal = {Frontiers in Robotics and AI}, publisher = {Frontiers}, issn = {2296-9144}, doi = {10.3389/frobt.2023.1108114}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-40592}, year = {2023}, language = {en} } @article{WojciechowskiPogscheba2022, author = {Wojciechowski, Manfred and Pogscheba, Patrick}, title = {Building a COVID-Safe Navigation App Using a Meta-Model Based Context Server}, series = {sensors}, volume = {22}, journal = {sensors}, number = {24}, publisher = {MDPI}, issn = {1424-8220}, doi = {10.3390/s22249890}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-39570}, pages = {1 -- 14}, year = {2022}, abstract = {Building context-aware applications is an already widely researched topic. It is our belief that context awareness has the potential to supplement the Internet of Things, when a suitable methodology including supporting tools will ease the development of context-aware applications. We believe that a meta-model based approach can be key to achieving this goal. In this paper, we present our meta-model based methodology, which allows us to define and build application-specific context models and the integration of sensor data without any programming. We describe how that methodology is applied with the implementation of a relatively simple context-aware COVID-safe navigation app. The outcome showed that programmers with no experience in context-awareness were able to understand the concepts easily and were able to effectively use it after receiving a short training. Therefore, context-awareness is able to be implemented within a short amount of time. We conclude that this can also be the case for the development of other context-aware applications, which have the same context-awareness characteristics. We have also identified further optimization potential, which we will discuss at the conclusion of this article.}, 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} } @article{AngladaTortMastersSteffensetal.2022, author = {Anglada-Tort, Manuel and Masters, Nikhil and Steffens, Jochen and North, Adrian and M{\"u}llensiefen, Daniel}, title = {The Behavioural Economics of Music: Systematic review and future directions}, series = {Quarterly Journal of Experimental Psychology}, volume = {76}, journal = {Quarterly Journal of Experimental Psychology}, number = {5}, publisher = {SAGE}, isbn = {1747-0218}, issn = {1747-0226}, doi = {10.1177/17470218221113761}, year = {2022}, abstract = {Music-related decision-making encompasses a wide range of behaviours including those associated with listening choices, composition and performance, and decisions involving music education and therapy. 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} }
