März 2024, Hannover N2 - Psychoakustische Forschung setzt vermehrt auf den Einsatz audiovisueller virtueller Realität, um multimodaler Bewertungseinflüsse Rechnung zu tragen und so die damit zusammenhängende ökologische Validität und Alltagsnähe erzielter Ergebnisse aus Laborstudien zu erhöhen. Studien lassen jedoch vermuten, dass multimodale kontextbezogene Einflussfaktoren wie Raumdivergenz (hier Unterschiede in virtuell präsentiertem Raum und realer Umgebung) und intrinsische Erwartungshaltung einen signifikanten Einfluss auf die durch virtuelle Umgebungen induzierte kognitive Beanspruchung und somit die Geräuschbewertung haben. Um zu untersuchen, inwieweit physische Präsenz in einem zur VR-Umgebung visuell divergenten realen Raum die kognitive Belastung und die Geräuschbewertung beeinflussen, wurde ein 2x2 Between-Subjects-Experiment in einer virtuellen Büroumgebung durchgeführt. Dazu wurde eine reale Umgebung in Unity nachgebildet und den Versuchsteilnehmer*innen über ein Head-Mounted Display (HMD) präsentiert. Je nach Kondition wurde der Versuch im visuell kongruenten oder divergenten physischen Raum durchgeführt. Dynamische, binaurale, über Kopfhörer präsentierte Bürogeräuschszenarien sollten dabei in allen Konditionen, hinsichtlich ihrer Lautheit und Unangenehmheit retrospektiv bewertet werden. Um zusätzlich die induzierte kognitive Beanspruchung genauer zu untersuchen, wurden Teilnehmer*innen aufgefordert, je Kondition entweder lediglich die Geräusche zu bewerten oder zusätzlich parallel den Stroop-Test durchzuführen. Erste Ergebnisse weisen auf eine signifikante Veränderung der Geräuschwahrnehmung im divergenten Raum hin. Implikationen für das experimentelle Design im Bereich der psychoakustischen Forschung werden diskutiert.

März 2024, Hannover N2 - The development of the ISO 12913 has led to the creation of standardized methodologies for collecting and analyzing individual responses regarding acoustic environments in context, with the aim of enabling comparability, replicability, and the development of modelling algorithms in soundscape prediction and design tasks. The development of methods to represent and explore soundscape data has the potential to facilitate deeper insights into different datasets. Although it is unlikely that any single method will sufficiently capture all information in empirical studies, attempts are worthwhile to facilitate advancements in this realm. Therefore, we propose a web application that fosters an interactive exploration of datasets based on the ISO 12913. The application facilitates a comprehensive soundscape search using the 8 items of the standard, 8 features characterizing the soundscape (e.g., intensities of natural, human, and technical sound sources heard), and 10 distinct acoustic features. The search encompasses all possible combinations of these components, thus facilitating detailed exploration, offering an in-depth dataset overview, and enabling the comparison of different datasets. Further functionalities include text searching and the option to download, save, and load selected soundscapes, enhancing control and flexibility in the design of empirical studies and supporting urban planners in understanding various soundscape items.

März 2024, Hannover N2 - Understanding people's perception of everyday sound involves a complex interplay of various acoustic and non-acoustic factors. Our objective is to uncover important predictors for predicting real indoor soundscapes. To this end, we re-analyzed soundscape data recorded and evaluated by individuals in their homes, aiming for the utmost ecological validity. Given the intricate nature of sound perception and potential non-linear effects of acoustic and psychoacoustic predictors, we utilized machine-learning methods combined with hierarchical linear modeling to analyze 6375 soundscapes from 96 participants including acoustical, psychoacoustical, as well as situational und person-related predictors. Based on this analysis, we measured both the variability within and between subjects and obtained model fits for the prediction of both soundscape pleasantness and eventfulness. In order to discuss cases where predictions for known individuals or places are of interest, we employed (nested) cross-validation using different data-splitting methods. By doing so, our study sheds light on the generalizability of empirical findings when predicting soundscape evaluations for unknown or known subjects and thus supports a deeper understanding of everyday sound perception.

[Vortrag] T2 - Fortschritte der Akustik - DAGA 2024, 18. - 21. März 2024, Hannover N2 - The Lombard Effect and its impact on human speech production, also known as ‘Lombard Speech’, have been investigated in numerous scientific studies. It is known that the intensity, but also the type of background noise can affect Lombard Speech. By contrast, the potential effect of a gradual reduction of the amplitude of the background noise has received little attention in previous research. To test for such an effect, we split 34 participants into couples and had them orally compare images. In the experimental condition, there was background noise (masker) whose amplitude was reduced from 70 to 50 dB(A) over a period of 100 seconds. Measures of speech production after this decay were compared to those of a reference condition in which the masker was constantly at 50 dB(A). We hypothesized that speech production due to prior exposure to a louder masker would show a stronger expression of Lombard Speech in the experimental compared to the reference condition. The results showed a significant difference regarding the level of the first formant F1 across conditions, but not regarding the overall dB(A) level. However, tendencies could be identified, which can serve as a basis for further investigations.

[Vortrag] T2 - Fortschritte der Akustik - DAGA 2024, 18. - 21. März 2024, Hannover N2 - Noise sensitivity is a widely used, yet inconsistently defined, concept of being disturbed by environmental noise, independent of loudness levels. The origins of noise sensitivity are mostly unclear, but it has a higher prevalence among people with attention deficit hyperactivity disorder and autism, and could be caused by increased neural excitation due to sound, resulting in increased cognitive load. In this case, noise sensitivity can be expected to decrease people’s mental performance in both auditory and non-auditory tasks. The former was tested in an experiment using a dual-task paradigm where participants had to solve a visual task in the presence of environmental sounds and afterwards had to recall which sounds they perceived and to evaluate the overall soundscape pleasantness and loudness. Preliminary results indicate that participants’ noise sensitivity is positively correlated with the experienced cognitive load as well as with loudness and unpleasantness judgments. Also, noise sensitivity was negatively associated with the performance in the recall task and the test-retest-reliability of their judgments. These findings support the idea that noise sensitivity is a consequence of difficulties in filtering irrelevant auditory information. Y1 - 2024 PB - Deutsche Gesellschaft für Akustik e.V.

Um Empfehlungen hinsichtlich optimaler Nachhallzeiten sowie beobachtete Zusammenhänge zwischen akustischen und nichtakustischen Faktoren bei Restaurantbesuchen zu überprüfen und im Hinblick auf verschiedene Restaurantkategorien zu erweitern, wurden in der vorliegenden Studie 20 Restaurants in Berlin und NRW mit insgesamt mehr als 600 Gästen untersucht. Hierbei wurden sowohl die Nachhallzeit als auch der Lautstärkepegel sowie die Anzahl der Gäste im Raum über die Zeit erfasst. Mittels elektronischem Fragebogen wurden Soundscape-Parameter, Besuchsmotive sowie die empfundene Sprachverständlichkeit und Restaurantqualität erhoben. Erste Ergebnisse zeigen einen großen Zusammenhang zwischen objektiven akustischen Größen und wahrgenommener akustischer Angenehmheit und Sprachverständlichkeit, welcher je nach Restaurantkategorie variiert. Die Daten zeigen weiterhin, dass sich die akustische Angenehmheit nicht vollständig durch die Sprachverständlichkeit im Restaurant aufklären lässt. Implikationen für das akustische Design von Restaurants im Spannungsfeld zwischen Ruhe und Lebendigkeit werden diskutiert.

That is, purposeful sequencing can create an emotional journey and suspense (Lehne & Kölsch, 2015), tell a story or reinforce a particular concept or theme in the artist's music. Aim(s) This study thus aimed on examining the evolution of albums over the course of pop music history and on unveiling patterns (i.e. clusters) and temporal shifts in emotion- related album dramaturgy dependent on the cultural context (in terms of genres) by utilizing advanced computational methods. Methods We first created a dataset by scraping titles and artists of the weekly Top 10 albums (n = 14.394) from the Billboard.com charts from 1957 to 2022. We further extracted the emotion-related audio descriptors ‘valence’ and ‘energy’ from the Spotify Developer API for each track of the corresponding album, resulting in two-dimensional time series. We then employed Deep Time Series Embedding Clustering (DeTSEC; lenco et al., 2020) which can handle multivariate time series of different length. Finally, k-means clustering was applied on the embeddings produced by the DeTSEC, resulting in a 12 cluster solution. Results To facilitate the interpretation of our solution, we determined the most representative album of a cluster using the smallest Euclidean distance to its centroid. Preliminary time series analysis of the resulting 12 albums confirm different emotional trajectories of the respective clusters, for instance showing decreasing valence and arousal values over time for “I am up” by Young Thug (Cluster 6) or highest valence and arousal values at the beginning and the end of the album for“The New Classic” by Iggy Azalea (Cluster 12). Furthermore, Chi² tests revealed significant associations between an album’s cluster membership and both its year of release and its genre. Discussion and Conclusion The study constitutes a first step in shedding light on the evolution of albums in modern popular music since its emergence. It further provides an insight into how temporal dramaturgies in terms of the emotion-related arrangement of songs of albums differ across genres and undergo cultural trends and temporal shifts.

Real-time audio analysis and crossmodal correspondences were used as design guidelines for creating the visualization, which was presented through a head-mounted-display. To assess the impact of the music visualization on the audience’s aesthetic experience, a baseline visualization was designed, featuring the same visual elements but with random changes of color and movement. The audience’s aesthetic experience of the two conditions (i.e., listening to the same song with different visualizations) was assessed using the Aesthetic Emotions Scale (AESTHEMOS) questionnaire. Additionally, participants answered questions regarding the perceived audiovisual congruence of the stimuli and questionnaires about individual musicality and aesthetic receptivity. The results show that the visualization controlled by real-time audio analysis was associated with a slightly enhanced aesthetic experience of the audiovisual composition compared to the randomized visualization, thereby supporting similar findings reported in the literature. Furthermore, the tested personal characteristics of the participants did not significantly affect aesthetic experience. Significant correlations between these characteristics and the aesthetic experience were observed only when the ratings were averaged across conditions. An open interview provided deeper insights into the participants’ overall experiences of the live music performance. The results of the study offer insights into the development of real-time music visualization in mixed reality, examines how the specific audiovisual stimuli employed influence the aesthetic experience, and provides potential technical guidelines for creating new concert formats.

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 RAQI 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.

In this paper, we investigated the complex interplay between room acoustics, soundscape evaluation, non-acoustical aspects of a restaurant visit and overall restaurant quality. Based on acoustical measurements and reports from 142 persons visiting 12 restaurants in Berlin, we propose a structural equation model including both acoustical and non- acoustical factors and yielding a good overall fit. The model, for instance, suggests that the A-weighted sound level negatively impacts the assessment of overall restaurant quality, while the effect of soundscape pleasantness on overall restaurant quality is mediated by the restaurant’s perceived atmosphere. Moreover, the reverberation time was found to be effective predominantly through its effect on sound strength, which leads patrons to increasingly raise their speech level to ensure intelligibility. These results thus emphasize the need to design actively the restaurant’s acoustical atmosphere beyond pure loudness reduction which involves a specific trade-off between comfort and liveliness, depending on the desired character of the place.

In the study, 105 participants recorded 6594 sound environments in their homes, which were then evaluated based on the Experience Sampling Method. Hierarchical linear regressions using a loudness level based on ISO 532-1 allowed for obtaining the best model fits for predicting perceived loudness and explaining the highest variance. LAeq and LAF5 provided comparable results and may require less computational effort. However, the analysis shows that only one-third of the variance explained by fixed effects was attributable to the loudness level. Sixteen percent stemmed from perceived properties of the soundscape; 1% were attributable to relatively temporally stable, person-related predictors like participants' age; non-auditory situational predictors made no additional contribution. The results thus did not confirm previous findings on loudness perception under laboratory conditions, emphasizing the importance of the situational context. Along with the current paper, a comprehensive dataset, including the assessed person-related, situational, and sound-related measures as well as LAeq time-series and third-octave spectrograms, is provided to enable further research on sound perception, indoor soundscapes, and emotion.

Music streaming services have changed how music is played and perceived, but also how it is managed by individuals. Voice interfaces to such services are becoming increasingly common, for example through voice assistants on mobile and smart devices, and have the potential to further change personal music management by introducing new beneficial features and new challenges. Method. To explore the implications of voice assistants for personal music listening and management we surveyed 248 participants online and in a lab setting to investigate (a) in which situations people use voice assistants to play music, (b) how the situations compare to established activities common during non-voice assistant music listening, and (c) what kinds of commands they use. Analysis. We categorised 653 situations of voice assistant use, which reflect differences to non-voice assistant music listening, and established 11 command types, which mostly reflect finding or refinding activities but also indicate keeping and organisation activities. Results. Voice assistants have some benefits for music listening and personal music management, but also a notable lack of support for traditional personal information management activities, like browsing, that are common when managing music. Conclusion. Having characterised the use of voice assistants to play music, we consider their role in personal music management and make suggestions for improved design and future research.

This bias supposedly roots in an adaptation of perceptual loudness scaling to the laboratory environment, that is overall quieter than urban outdoor soundscapes. To gain further insights into the nature of such loudness bias, we conducted a listening experiment in both field and laboratory using a within-subjects design. Thirty-one participants visited a street and listened to the environmental sounds for one minute, while these sounds were also recorded using a dummy head. Thereafter, they listened to the recording in a quiet laboratory nearby and adjusted its level as they remembered it. About half of the sample did this immediately, the other half about 20 minutes after the recording. Results confirm a bias towards lower levels with a mean of about 8.9 dB, regardless of the time between the recording and the reproduction in the laboratory. Also, participants with higher musical abilities tended to select higher, more accurate levels, whereas noise-sensitive participants deemed lower levels appropriate. Results suggest that the hypothesized adaptation of perceptual scaling to the laboratory happens immediately and is affected by individual factors.

However, recent studies suggest that virtual environments can alter mental effort compared to real-world settings, for example, through increased perceptual complexity which in turn may affect auditory perception.This could bias experimental outcomes and compromise the ecological validity of studies conducted in VR. To investigate this, a 2 × 2 between-subjects experiment was conducted to assess whether VR environments increase mental effort and thereby influence auditory perception. A real office environment was visually reconstructed in Unity and presented to the participants via a head-mounted display (HMD) and compared to its real counterpart. Participants in both environments were asked to retrospectively rate the loudness and unpleasantness of dynamically rendered binaural office noise scenarios presented via headphones and to report perceived sound sources. Moreover, participants were divided into two groups to induce different levels of mental effort. One group was asked to listen only to the sounds, while the other performed the Stroop Color-Word interference test in parallel. The results show no significant difference in the overall induced mental effort between environment conditions. Furthermore, performing the Stroop test had an effect on loudness and unpleasantness that was mediated by subjective effort. The results also suggest that auditory jugment depend primarily on individual sound properties, regardless of the visual environment.

Thus, we argue that, on a perceptual level, reverberation basically breaks down into interaural differences and spectro-temporal cues and that the separation of a perceived timbre into a sound source and a surrounding room is a purely cognitive process. To investigate the connection between the perception of reverberation cues and timbre analysis, the sensitivity for changes in reverberation was compared to timbre perception abilities. The Timbre Perception Test was used to measure the perception of the temporal envelope, spectral centroid, and spectral flux of artificial sounds. Sensitivity for changes in reverberation time was tested with a discrimination task using speech and noise with speech-alike spectral and temporal envelopes as source signals. Musical and acoustical expertise was assessed through the Goldsmiths Musical Sophistication Index and self-reports on experience with and knowledge of acoustics. There was a considerable correlation between timbre and reverberance perception ability, but timbre perception and academic experience predicted only 41% of the variance in reverberance perception. Still, perception abilities related to similar acoustical phenomena seem to be better indicators of listening skills than self-reports on acoustical or musical expertise.

This study involved analyzing a sample of 1,412 freely and publicly expressed music requests from children aged between 4 and 11 years taken from a German radio program, with regard to age- and sex-specific differences. The music was categorized into genres, as listed on Spotify, and examined using methods of music information retrieval provided by the Spotify Developer application programming interface. Results showed that, at younger ages, the requests were generally more evenly distributed across different genres. Regarding single genres, we observed small positive relationships between age and the likelihood of requesting the genres pop or electro and small negative relationships between age and the likelihood of requesting A capella, German songwriter, indie, theme songs, or children's music. Furthermore, we found that boys requested significantly more rock or hip-hop, whereas girls had a higher tendency to ask for pop. Finally, age- (but no sex-) related differences regarding the Spotify features of valence and liveness of the requested music were found, which were related to the preference for children's music at younger ages. The results thus suggest that previous findings regarding differences between boys and girls and an increasing formation of distinct genre preferences during infancy also apply to single song requests made on a radio show.

JF - The Journal of the Acoustical Society of America N2 - Credibility is a crucial social factor that influences people's perception and decision-making. This study explores the acoustic attributes that define credible speech compared to neutral and ironic speech. A custom-built German corpus was developed, containing speech samples recorded from amateurs to enhance ecological validity. The study extracted a broad set of audio features from these samples, employing recursive feature elimination to identify the most influential attributes. These were then analyzed using a machine-learning-supported multinomial logistic regression model. The results indicated significant differences in the acoustic features associated with credible speech compared to neutral and ironic speech. Key findings include the role of a higher energy level (1st mel-frequency cepstral coefficient) in credible compared to neutral and ironic speech and a higher speaking rate in both credible and ironic compared to neutral speech. Also, irony is characterized by more high-frequency content (mean spectral centroid) compared to credible or neutral speech. Gender differences in spoken irony involve a greater influence of speaking rate in women's speech, while high pitch plays a more significant role in men's speech. This research thus contributes to the understanding of how credibility is conveyed through speech and offers insights for applications in communication, media, and artificial intelligence. The study also highlights the methodological advancements made by incorporating a diverse range of acoustic features and employing a robust machine-learning framework.
