Hearing aid evaluation for music: Accounting for acoustical variability of music stimuli.

Music is an important signal class for hearing aids, and musical genre is often used as a descriptor for stimulus selection. However, little research has systematically investigated the acoustical properties of musical genres with respect to hearing aid amplification. Here, extracts from a combination of two comprehensive music databases were acoustically analyzed. Considerable overlap in acoustic descriptor space between genres emerged. By simulating hearing aid processing, it was shown that effects of amplification regarding dynamic range compression and spectral weighting differed across musical genres, underlining the critical role of systematic stimulus selection for research on music and hearing aids.

Transforming text to music using artificial intelligence improves the frontal lobe function of normal older adults.

INTRODUCTION: Recent advances in artificial intelligence (AI) have been substantial. We investigated the effectiveness of an online meeting in which normal older adults (otokai) used a music-generative AI that transforms text to music (Music Trinity Generative Algorithm-Human Refined [MusicTGA-HR]). METHODS: One hundred eighteen community-dwelling, cognitively normal older adults were recruited through the internet (64 men, 54 women; mean age: 69.4 ± 4.4 years). Using MusicTGA-HR, the participants chose music that they thought was the most suitable to a given theme. We established 11 classes of 7-10 members and one instructor each. Each class held an online meeting once a week, and each participant presented the music they chose. The other participants and the instructor then commented on the music. Neuropsychological assessments were performed before and after the intervention for 6 months, and the results before and after the intervention were statistically analyzed. RESULTS: The category and letter word fluencies (WFs) were significantly improved (category WF: p = .003; letter WF: p = .036), and the time of the Trail-Making Test-B was also significantly shortened (p = .039). The Brain Assessment, an online cognitive test we developed, showed significant improvement in the memory of numbers (p < .001). CONCLUSION: The online meeting of the otokai, which used music-generative AI, improved the frontal lobe function and memory of independent normal older adults.

Comparative analysis of noise and music exposure on inflammatory responses on lipopolysaccharide-induced septic rats.

OBJECTIVE: Environmental factors such as noise and music can significantly impact physiological responses, including inflammation. This study explored how environmental factors like noise and music affect lipopolysaccharide (LPS)-induced inflammation, with a focus on systemic and organ-specific responses. MATERIALS AND METHODS: 24 Wistar rats were divided into four groups (n = 6 per group): Control group, LPS group, noise-exposed group, and music-exposed group. All rats, except for the Control group, received 10 mg/kg LPS intraperitoneally. The rats in the noise-exposed group were exposed to 95 dB noise, and the music-exposed group listened to Mozart's K. 448 music (65-75 dB) for 1 h daily over 7 days. An enzyme-linked immunosorbent assay was utilized to detect the levels of inflammatory cytokines, including tumor necrosis factor-α (TNF-α) and interleukin-1ß (IL-1ß), in serum and tissues (lung, liver, and kidney). Western blot examined the phosphorylation levels of nuclear factor-κB (NF-κB) p65 in organ tissues. RESULTS: Compared with the Control group, LPS-induced sepsis rats displayed a significant increase in the levels of TNF-α and IL-1ß in serum, lung, liver, and kidney tissues, as well as a remarkable elevation in the p-NF-κB p65 protein expression in lung, liver, and kidney tissues. Noise exposure further amplified these inflammatory markers, while music exposure reduced them in LPS-induced sepsis rats. CONCLUSION: Noise exposure exacerbates inflammation by activating the NF-κB pathway, leading to the up-regulation of inflammatory markers during sepsis. On the contrary, music exposure inhibits NF-κB signaling, indicating a potential therapeutic effect in reducing inflammation.

Impact of music learning on students' psychological development with mediating role of self-efficacy and self-esteem.

Professionals and academics have recently placed a greater emphasis on comprehending the elements that go into improving students' psychological wellbeing. Students frequently face major obstacles as a result of the rigorous nature of academic life, which can result in problems like tension, depression and other psychological health concerns. These complications have a long-lasting influence on their future aspirations in addition to affecting their academic achievement. This study determined the effects of music learning on students' academic performance and psychological well-being. The mediating role of self-efficacy and self-esteem are also examined in this study. The data is collected from 326 students in Chinese universities and applied structural equation modeling for empirical analysis. The findings show that music education improves the students' psychological well-being, which in turn improves their academic performance. Additionally, psychological health is a major factor in improving the academic performance. There is significant mediating impact of self-efficacy and self-esteem in relationship between mental well-being and music education. To improve students' psychological health, it is suggested that policy makers should consider the integration of music education into academic settings.

An Audiovisual Correlation Matching Method Based on Fine-Grained Emotion and Feature Fusion.

Most existing intelligent editing tools for music and video rely on the cross-modal matching technology of the affective consistency or the similarity of feature representations. However, these methods are not fully applicable to complex audiovisual matching scenarios, resulting in low matching accuracy and suboptimal audience perceptual effects due to ambiguous matching rules and associated factors. To address these limitations, this paper focuses on both the similarity and integration of affective distribution for the artistic audiovisual works of movie and television video and music. Based on the rich emotional perception elements, we propose a hybrid matching model based on feature canonical correlation analysis (CCA) and fine-grained affective similarity. The model refines KCCA fusion features by analyzing both matched and unmatched music-video pairs. Subsequently, the model employs XGBoost to predict relevance and to compute similarity by considering fine-grained affective semantic distance as well as affective factor distance. Ultimately, the matching prediction values are obtained through weight allocation. Experimental results on a self-built dataset demonstrate that the proposed affective matching model balances feature parameters and affective semantic cognitions, yielding relatively high prediction accuracy and better subjective experience of audiovisual association. This paper is crucial for exploring the affective association mechanisms of audiovisual objects from a sensory perspective and improving related intelligent tools, thereby offering a novel technical approach to retrieval and matching in music-video editing.

Using Wearable Sensors to Study Musical Experience: A Systematic Review.

Over the last few decades, a growing number of studies have used wearable technologies, such as inertial and pressure sensors, to investigate various domains of music experience, from performance to education. In this paper, we systematically review this body of literature using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) method. The initial search yielded a total of 359 records. After removing duplicates and screening for content, 23 records were deemed fully eligible for further analysis. Studies were grouped into four categories based on their main objective, namely performance-oriented systems, measuring physiological parameters, gesture recognition, and sensory mapping. The reviewed literature demonstrated the various ways in which wearable systems impact musical contexts, from the design of multi-sensory instruments to systems monitoring key learning parameters. Limitations also emerged, mostly related to the technology's comfort and usability, and directions for future research in wearables and music are outlined.

Operatic voices engage the default mode network in professional opera singers.

Extensive research with musicians has shown that instrumental musical training can have a profound impact on how acoustic features are processed in the brain. However, less is known about the influence of singing training on neural activity during voice perception, particularly in response to salient acoustic features, such as the vocal vibrato in operatic singing. To address this gap, the present study employed functional magnetic resonance imaging (fMRI) to measure brain responses in trained opera singers and musically untrained controls listening to recordings of opera singers performing in two distinct styles: a full operatic voice with vibrato, and a straight voice without vibrato. Results indicated that for opera singers, perception of operatic voice led to differential fMRI activations in bilateral auditory cortical regions and the default mode network. In contrast, musically untrained controls exhibited differences only in bilateral auditory cortex. These results suggest that operatic singing training triggers experience-dependent neural changes in the brain that activate self-referential networks, possibly through embodiment of acoustic features associated with one's own singing style.

The role of audiovisual congruence in aesthetic appreciation of contemporary music and visual art.

Does congruence between auditory and visual modalities affect aesthetic experience? While cross-modal correspondences between vision and hearing are well-documented, previous studies show conflicting results regarding whether audiovisual correspondence affects subjective aesthetic experience. Here, in collaboration with the Kentler International Drawing Space (NYC, USA), we depart from previous research by using music specifically composed to pair with visual art in the professionally-curated Music as Image and Metaphor exhibition. Our pre-registered online experiment consisted of 4 conditions: Audio, Visual, Audio-Visual-Intended (artist-intended pairing of art/music), and Audio-Visual-Random (random shuffling). Participants (N = 201) were presented with 16 pieces and could click to proceed to the next piece whenever they liked. We used time spent as an implicit index of aesthetic interest. Additionally, after each piece, participants were asked about their subjective experience (e.g., feeling moved). We found that participants spent significantly more time with Audio, followed by Audiovisual, followed by Visual pieces; however, they felt most moved in the Audiovisual (bi-modal) conditions. Ratings of audiovisual correspondence were significantly higher for the Audiovisual-Intended compared to Audiovisual-Random condition; interestingly, though, there were no significant differences between intended and random conditions on any other subjective rating scale, or for time spent. Collectively, these results call into question the relationship between cross-modal correspondence and aesthetic appreciation. Additionally, the results complicate the use of time spent as an implicit measure of aesthetic experience.

Analyzing the Influence of Video Game and Music Engagement on Technical Skills Acquisition in Dental Students in Preclinical Phase: Protocol for a Prospective, Controlled, Longitudinal Study.

BACKGROUND: The practice of dental surgery requires a few different skills, including mental rotation of an object, precision of movement with good hand-eye coordination, and speed of technical movement. Learning these different skills begins during the preclinical phase of dental student training. Moreover, playing a musical instrument or video game seems to promote the early development of these skills. However, we found that studies specifically addressing this issue in the field of dental education are lacking. OBJECTIVE: The main aims of this study are to evaluate whether the ability to mentally represent a volume in 3D, the precision of gestures with their right and left hand, or the speed of gesture execution is better at baseline or progresses faster for players (video games or music or both). METHODS: A prospective monocentric controlled and longitudinal study will be conducted from September 2023 and will last until April 2025 in the Faculty of Dental Surgery of Nantes. Participants were students before starting their preclinical training. Different tests will be used such as Vandenberg and Kuse's mental rotation test, the modified Precision Manual Dexterity (PMD), and performing a pulpotomy on a permanent tooth. This protocol was approved by the Ethics, Deontology, and Scientific Integrity Committee of Nantes University (institutional review board approval number IORG0011023). RESULTS: A total of 86 second-year dental surgery students were enrolled to participate in the study in September 2023. They will take part in 4 iterations of the study, the last of which will take place in April 2025. CONCLUSIONS: Playing video games or a musical instrument or both could be a potential tool for initiating or facilitating the learning of certain technical skills in dental surgery.

Effect of short-term exposure to Raag Bilawal of North Indian classical music on young Indian adults: a high-density electroencephalogram microstate study.

Introduction: the objective of the study was to find out the microstate map topographies and their parameters generated during the resting state and during listening to North Indian classical Music Raag 'the Raag Bilawal'. It was hypothesized that in the resting state and during listening to music conditions, there would be a difference in microstate parameters i.e. mean duration, global explained variance (GEV), and time coverage. Methods: a 128-channel electroencephalogram (EEG) was recorded for 12 Indian subjects (average age 26.1+1.4 years) while resting and listening to music using the EEG microstate investigation. Investigation and comparison of the microstate parameters were the mean duration, global explained variance (GEV), and time coverage between both conditions were performed. Results: seven microstate maps were found to represent the resting state and listening to music condition, four canonical and three novel maps. No statistically significant difference was found between the two conditions for time coverage and mean duration. The statistical significance levels of the map-1, map-2, map-3, map-4, map-5, map-6, and map-7 for the mean duration were 0.4, 0.6, 0.97, 0.34, 0.32, 0.69, and 0.29 respectively; and for time coverage were 0.92, 0.92, 0.96, 0.64, 0.78, 0.38, and 0.76 respectively. Map-1, map-4, and map-7 were the three novel maps we found in our study. Conclusion: similarities regarding stability and predominance of maps with small vulnerability exist in both conditions indicating that phonological, visual, and dorsal attention networks may be activated in both resting state and listening to music condition.

Workplace Injury Prevention and Wellness Program for Orchestra Musicians: A Randomized Controlled Trial.

OBJECTIVE: To evaluate the effect of a workplace injury prevention and wellness program compared to no intervention (control) on musicians' playing-related musculoskeletal pain intensity. The hypothesis was that musicians who completed the program would have a greater reduction in pain intensity than the control group. DESIGN: Pragmatic parallel randomized controlled trial. METHODS: Sixty-five orchestra musicians were recruited and completed patient-reported outcome measures (primary outcome: pain intensity over 11 months, using the Musculoskeletal Pain Intensity and Interference Questionnaire for Musicians; range: 0-40; lower is better) at baseline, 14 weeks (T1), and 11 months (T2). Following baseline assessment, participants were randomly assigned to the intervention (n = 33) or control (n = 32) groups, stratified by instrument and pain prevalence. The intervention group received a 14-week injury prevention and wellness program including education and exercise; the control group received no intervention. RESULTS: Pain intensity means (standard deviation) were 7.8 (6.2), 8.0 (7.5), and 8.6 (5.7) in the control group, and 9.0 (6.6), 5.0 (4.2), and 6.7 (6.6) in the intervention group at T0, T1, and T2, respectively. Using intention-to-treat analyses (3 dropouts, n = 65 analyzed), between-group differences in pain intensity (95% confidence interval) were T1-T0: -4.2 (-7.5, -0.9); T2-T0: -3.7 (-7.1, -0.3), type III (overall) P = .03, favoring the intervention group. No adverse events were reported. CONCLUSION: A workplace injury prevention and wellness program may have a clinically meaningful effect on reducing orchestra musicians' pain intensity.

Instrumental music training relates to intensity assessment but not emotional prosody recognition in Mandarin.

Building on research demonstrating the benefits of music training for emotional prosody recognition in nontonal languages, this study delves into its unexplored influence on tonal languages. In tonal languages, the acoustic similarity between lexical tones and music, along with the dual role of pitch in conveying lexical and affective meanings, create a unique interplay. We evaluated 72 participants, half of whom had extensive instrumental music training, with the other half serving as demographically matched controls. All participants completed an online test consisting of 210 Chinese pseudosentences, each designed to express one of five emotions: happiness, sadness, fear, anger, or neutrality. Our robust statistical analyses, which included effect size estimates and Bayesian factors, revealed that music and nonmusic groups exhibit similar abilities in identifying the emotional prosody of various emotions. However, the music group attributed higher intensity ratings to emotional prosodies of happiness, fear, and anger compared to the nonmusic group. These findings suggest that while instrumental music training is not related to emotional prosody recognition, it does appear to be related to perceived emotional intensity. This dissociation between emotion recognition and intensity evaluation adds a new piece to the puzzle of the complex relationship between music training and emotion perception in tonal languages.

Children with developmental coordination disorder display atypical interhemispheric connectivity during conscious and subconscious rhythmic auditory-motor synchronization.

Children with developmental coordination disorder (DCD) display difficulties in perception-action coupling when engaging in tasks requiring predictive timing. We investigated the influence of awareness on auditory-motor adjustments to small and large rhythmic perturbations in the auditory sequence to examine whether children synchronize their movements automatically or through planning and whether those adjustments occur consciously or subconsciously. Electroencephalography (EEG) was used to assess functional connectivity patterns underlying different adjustment strategies. Thirty-two children aged 7-11 participated, including children with DCD and their typically developing (TD) peers with and without musical training. All children automatically adjusted their motor responses to small rhythmic perturbations by employing the anticipatory mode, even when those changes were consciously undetectable. Planned adjustments occurred only when children consciously detected large fluctuations (Δ 20%), which required a shift from predictive to reactive strategies. Compared to TD peers, children with DCD showed reduced interhemispheric connectivity during planned adjustments and displayed similar neural patterns regardless of task constraints. Notably, they benefited from rhythmic entrainment despite having increased variability and lower perceptual acuity. Musical training was associated with enhanced auditory-perceptual timing, reduced variability, and increased interhemispheric coherence. These insights are important for the therapeutic application of auditory/rhythm-based interventions in children with DCD.

Anhedonia severity mediates the relationship between attentional networks recruitment and emotional blunting during music listening.

Emotion studies have commonly reported impaired emotional processing in individuals with heightened anhedonic depressive symptoms, as typically measured by collecting single subjective ratings for a given emotional cue. However, the interindividual variation in moment-to-moment emotional reactivity, and associated time-varying brain networks recruitment as emotions are unfolding, remains unclear. In this study, we filled this gap by using the unique temporal characteristics of music to investigate behavioural and brain network dynamics as a function of anhedonic depressive symptoms severity. Thirty-one neurotypical participants aged 18-30 years completed anhedonic depression questionnaires and then continuously rated happy, neutral and sad pieces of music whilst undergoing MRI scanning. Using a unique combination of dynamic approaches to behavioural (i.e., emotion dynamics) and fMRI (i.e., leading eigenvector dynamics analysis; LEiDA) data analysis, we found that participants higher in anhedonic depressive symptoms exhibited increased recruitment of attentional networks and blunted emotional response to both happy and sad musical excerpts. Anhedonic depression mediated the relationship between attentional networks recruitment and emotional blunting, and the elevated recruitment of attentional networks during emotional pieces of music carried over into subsequent neutral music. Future studies are needed to investigate whether these findings could be generalised to a clinical population (i.e., major depressive disorder).

Creating and Reliving the Moment: Using Musical Improvisation and Care Aesthetics as a Lens of Connection and Self-Expression for Younger People Living with Dementia.

Musical improvisation is a generative process of spontaneously creating music 'in the moment'. For people with young onset dementia, musical improvisation provides an extended opportunity for creative self-expression and connection to one's own body and life story. Using visual research methods, including video elicitation interviews, this paper explores the 'in the moment' musical experiences of five people living with young onset dementia who took part in a 15-week improvised music-making programme (Music in Mind). We frame the exploration of the group's musical experiences through the emerging lens of 'care aesthetics'-a concept that identifies the sensory relations and embodied practices between two (or more) people in a caring relationship. In the context of this analysis, we look to the caring practices by, with, and between people living with dementia, their family members, and the musicians who lead the programme and the relationship of these practices to feelings of self-expression and meaningful connection. Musical improvisation has the potential to support the psychological, social, and spiritual wellbeing of people living with young onset dementia. In applying a lens of care aesthetics, it is possible to observe the micro-level experiences of people living with dementia and their family carers.

The effectiveness of live music in reducing anxiety and depression among patients undergoing haemodialysis. A randomised controlled pilot study.

BACKGROUND: Anxiety and depression are highly prevalent disorders among individuals undergoing chronic haemodialysis. For patients with kidney disease, the haemodialysis process often exacerbates these conditions. This study aims to investigate the effects of listening to live classical music on anxiety and depression scales during haemodialysis sessions. METHODS: A randomised clinical trial was conducted with a group of patients who listened to live classical music during haemodialysis sessions, while the control group received treatment as usual. Anxiety and depression levels were assessed at baseline and after 4 weeks of listening to live music. The study comprised 90 patients. RESULTS: The results demonstrated a significant decrease in anxiety and depression among the intervention group, who listened to music, compared to the control group, who did not receive this intervention. Specifically, the intervention group, presented a decrease in score on the anxiety scale of -5.35 (p < 0.001) points on average and a decrease in score on the depression scale of -5.88 (p < 0.001) points on average, while in the control group the levels worsened with the progression of time. CONCLUSION: It is concluded that listening to live classical music during haemodialysis sessions reduces anxiety and depression levels in HD patients. This conclusion adds value to listening to live music in the hospital context, specifically in this case, in haemodialysis rooms.

Evaluating music education interventions for mental health in Chinese university student: a dual fuzzy analytic method.

This study addresses the growing anxiety and depression among Chinese university students by evaluating and ranking music education strategies to alleviate these issues. We integrates Fuzzy Analytic Hierarchy Process (FAHP) and Fuzzy Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). FAHP was utilized to determine the weight of factors such as academic pressures, social relationships, and cultural norms, while fuzzy TOPSIS ranked the effectiveness of music education interventions based on these weights. The results revealed that 'Mental health stigma' and 'Academic Pressures and Rigidity' are among the highest weighted factors, significantly impacting student anxiety. 'Music Appreciation and Music-Based Self-Care' emerged as the most effective strategy. These results highlight the importance of direct involvement in music-related activities for improving student mental health.
