This study analyzes the historical evolution of topics and conveyed affect in popular music lyrics in Germany from 1954 to 2022, using LDA-based topic modeling and transformer-based sentiment analysis. These results show that Love & Relationships is the most referenced topic, with Dreams & Longings prominent until the mid-1960s and Society & Status rising from 2017. The sentiment analysis reveals a significant decline in positive sentiment since the mid-1960s, accompanied by increases in negative, ambiguous, and neutral sentiments. These trends may reflect broader societal changes, including shifts in cultural values, rising individualism, and increasing mental health issues. The study highlights the evolving nature of popular music and its reflection of social dynamics.

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.

These sounds were also recorded using a dummy head. Afterwards, participants listened to the recording in a quiet laboratory and adjusted its level as they remembered it. About half of the sample did this immediately, the other half about 20 min after the recording, during which the performed another listening tests. Afterwards, previous experience with acoustics, musical sophistication and noise sensitivity were assessed. The results revealed a mean gain adjustment of 8.9 dB below the original. The data uploaded here comprises participants gain adjustment, the recording levels averaged other A) the entire recording and B) the first and last 7.5s or 15s, respecitvely and all questionnaire responses as well as aggregate scores for musical sophistication and noise sensitivity, as well as a binary categorization of the respondent into laymen and experienced, based on their previous experience with acoustics. For sociodemographic information, participants age, sex and educational degree are reported as well.

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.

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.
