However, these tests often target acoustic parameters other than those typically relevant in music such as pitch, rhythm, amplitude, or timbre. To assess the expertise in perceiving and understanding room acoustical phenomena, a listening test battery was constructed to measure the perceptual sensitivity and cognitive abilities in the identification of rooms with different reverberation times and different spectral envelopes. Performance in these tests was related to data from the Goldsmiths Musical Sophistication Index, self-reported previous experience in music recording and acoustics, and academic knowledge on acoustics. The data from 102 participants show that sensory and cognitive abilities are both correlated significantly with musical training, analytic listening skills, recording experience, and academic knowledge on acoustics, whereas general interest in and engagement with music do not show any significant correlations. The regression models, using only significantly correlated criteria of musicality and professional expertise, explain only small to moderate amounts (11%–28%) of the variance in the “room acoustic listening expertise” across the different tasks of the battery. Thus, the results suggest that the traditional criteria for selecting expert listeners in room acoustics are only weak predictors of their actual performances.

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.

Zur Beschreibung der Akustik von Aufführungsräumen haben sich dabei zahlreiche Messgrößen etabliert, welche bestimmte Wahrnehmungsqualitäten, wie z. B. die Halligkeit, abbilden sollen. Dem stellt jüngere Forschung rein perzeptive Messinventare gegenüber, die den Wahrnehmungseindruck als solchen, losgelöst vom physikalischen Ursprung, beschreiben. Dieser Artikel beschreibt einen Versuch, diese beiden Forschungsrichtungen zusammenzuführen, indem Bewertungen von Aufführungsräumen nach dem perzeptiven Room Acoustical Quality Index (RAQI) durch physikalische Messgrößen modelliert wurden, welche aus einfachen Impulsantwortmessungen ermittelt werden. Dazu wurde eine Auswahl raumakustischer Messgrößen auf fünf Dimensionen reduziert und diese als Prädiktoren für die einzelnen Wahrnehmungsgrößen des RAQI getestet. Die Berechnung dieser Prädiktionsmodelle wird vorgestellt und deren Präzision diskutiert. Anschließend wird die OPRA-Webanwendung vorgestellt, die sowohl die Berechnung der raumakustischen Messgrößen als auch die Prädiktion von RAQI-Wahrnehmungsgrößen für die drei Quellsignale Sprache, Orchester und Solotrompete im Browser ermöglicht.

N2 - Performance spaces have a substantial influence on the experience of musical performances, and numerous physical measures have been proposed to describe different aspects of the perceptual impact singular of a performance space. Recent research complements these physical measures with purely perceptual inventories that describe the auditory impression as such, and somewhat detached from its physical origin. This article describes an attempt to bring these two research directions together by modelling evaluations of performance spaces according to the subject-centered Room Acoustical Quality Index (RAQI) based on physical measures obtained from simple impulse response measurements. A selection of room acoustical parameters was reduced to five dimensions which were tested then as predictors for the perceptual qualities of the RAQI. The calculation of these prediction models is presented and the models’ prediction performance discussed. Then, the OPRA-online-tool is presented that enables both the calculation of the physical measures and the prediction of RAQI factors for the three source signals speech, orchestra and solo trumpet within the web browser. Even though the precision of the prediction models does not yet provide reliable estimates of all RAQI factors, OPRA allows a first assessment of the perceptual effect of performance spaces on speech and music.

[Vortrag] T2 - Fortschritte der Akustik - DAGA 2024 N2 - The perceived spatial impression is an important factor in the aesthetic appreciation of classical music recordings. Crucial aspects of spatial perception can be described by the attributes ensemble width, depth, envelopment, and reverberation duration. In a listening experiment, a sample of 30 experts rated 24 orchestra recordings by these attributes. To compare these ratings to signalrelated measures of spatial impression, an audio descriptor for the interaural cross-correlation coefficient in music recordings was chosen as a measure of perceived ensemble width. A second algorithm estimated the reverberation time from decay segments in the recorded music. Linear mixed-effects models were then used to test whether these two descriptors, combined with other audio features related to timbre, are suitable for predicting participants’ ratings of the perceptual attributes. Overall, results confirmed that the signal-related measures used can indeed predict perceptual attributes, with 41% of rating variance explained in the case of reverberation duration. In contrast, these objective measures turned out to be less accurate predictors of the perceived ensemble width, with a variance explanation of 21%. This study can thus be regarded as a starting point for further studies aiming to predict the perceived spatial impression in music recordings.

Most of this research, however, is either based on the evaluation of musical pieces that have been previously selected by adult experimenters, or self-reports on preferences for different musical styles. Aim(s) This study presents another methodological approach by collecting and analysing music that was freely requested on a children’s radio show. The aim was to test to what extent findings from self-reports and ratings of pre-selected music apply to this kind of data. Methods A sample of 1412 freely and publicly expressed music requests of children between 4 and 11 years was taken from a German radio program and analysed with regard to age- and sex-specific differences. The music was categorized into genres as listed on Spotify and examined by methods of Music Information Retrieval provided by the Spotify Developer API. Additionally, the music was genre-independently classified as children’s music. Results Results showed that, at younger ages, the requests were generally more evenly distributed across different genres. Regarding single genres, logistic regression models revealed small positive relationships between age and the likelihood of requesting the genres Pop and Electro and small negative relationships between age and the likelihood of requesting Acapella, German songwriter, Indie, theme songs, and children's music. Furthermore, contingency table analyses showed that boys requested significantly more Rock and Hip Hop, whereas girls had a higher tendency to ask for Pop. Finally, age was negatively correlated with the Spotify features valence and liveness of the requested music, which was related to the higher preference for children’s music at younger ages. Discussion and Conclusion The results suggest that previous findings regarding musically expressed gender roles and increasing formation of distinct genre preferences during infancy also apply to single song requests made on a radio show.

[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.

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.

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.
