Summary: This study found that classical singers have the ability to adjust their vocal productions to different styles. Whether it's opera, pop songs, or lullabies, classical singers demonstrate a high level of skill and versatility. There are variations in competence among singers, but this is not directly linked to their formal training.

Summary: Speaking and singing activities in enclosed spaces have been restricted due to the risk of COVID-19 transmission through virus-carrying aerosols. This study measured particle emission rates in children and found that they were significantly lower compared to adults. These findings can contribute to virus risk management in schools and extracurricular settings.

Summary: This study aims to enable machines to describe singing voice from the perspective of vocal pedagogy. A dataset called SVQTD is constructed and published for supervised learning. Different machine learning algorithms and feature extractors are utilized to classify singing voice attributes. Experimental results show that the DE-SVM model with ResNet as the feature extractor achieves the best performance.

Summary: This article investigates the changes in singing accuracy across different age groups and finds that singing accuracy improves significantly from childhood to young adulthood, unaffected by voice changes during adolescence, and remains at a high level for the rest of life without showing a strong age-related decline. Vocal or instrumental musical training has a significant positive impact on singing accuracy, especially in childhood.

Summary: Therapeutic applications of singing have been explored for acquired neurogenic communication disorders, but speech-language pathologists lack training and comprehensive protocols. Most clinicians recognize the benefits of group singing, but it is underutilized due to a lack of suitable choirs in their area.

Summary: This work introduces AffectMachine-Classical, a new music generation system capable of producing affective Classical music in real-time. It was designed to be used in biofeedback systems to help users become aware of and regulate their own dynamic affective states. The system has a rule-based, probabilistic architecture and has been validated through a listener study, showing its effectiveness in conveying target emotions to listeners. Future work aims to incorporate AffectMachine-Classical into biofeedback systems to enhance emotional well-being in listeners.

Summary: This article discusses the theory of aesthetic experience with music in specific situations using the sociological concept of the frame, focusing on the classical concert as a frame. It proposes an empirical research program to study the affordances and effects of different frames and frame components on the musical experience, aiming to tackle the question of whether modern music listening formats can accommodate classical concerts.

Summary: Music beats spoken language in uniquely identifying individuals in the Oyda and Yopno communities. Name tunes, short melodies that are unique to individuals, are used not only for everyday communication but also in ceremonial occasions. Unlike other musical surrogate speech systems, the Oyda and Yopno name tune systems continue to be used productively in the face of societal changes.

Summary: This study examined the impact of musicians' practice habits on their ability to cope with uncertainty and the effects of the COVID-19 pandemic. The findings suggest that musicians who are more internally self-motivated are more resilient and better able to manage their practice routines, while those who are more externally motivated experienced a decrease in practice time during lockdown.

Summary: This study used magnetic resonance imaging and audio recordings to investigate the morphology of the epilaryngeal tube during sustained phonation in male and female classically trained singers at different loudness conditions. The results suggest that male singers tend to narrow their epilaryngeal tube with increasing sound pressure level, while female singers do not. This indicates that strategies of vocal tract adjustments during loudness variation in classical singing appear to be gender specific.

Summary: This study shows that infection of COVID-19 is only possible when the viral load exceeds 10(8) viral copies/mL. Mathematical modeling and assumptions can be used to simplify the calculation of parameters related to infection prevention, such as the maximum number of people and the person-related virus-free air supply flow. The study also concludes that testing contributes the most to the joint protective effect, along with wearing masks and increasing ventilation.

Summary: Conventional heat supply systems for indoor environments have a low annual efficiency due to an oversupply in unoccupied periods. This study introduces a new method using low-capacity electric heating systems to achieve an occupancy-equivalent heating concept. The use of fast-responding infrared sensors allows for efficient control of these heating systems, preventing oversupplies and enabling rapid heating.

Summary: This study investigated two choir outbreaks and found that long-range transmission plays a significant role in the spread of the pandemic. The study revealed that particle emission rate was 7 times higher during singing compared to talking, and one choir had much higher transmission risk than the other. The results highlight the importance of non-pharmaceutical interventions, especially in indoor settings where aerosols can accumulate.

Summary: This study focuses on the voice efficiency of different singing styles, finding that Opera and Belting are highly efficient strategies while Twang and Belting use similar vowels but with different resonant characteristics. Speech is associated with efficient energy transfer, but is more susceptible to noise interference, while Falsetto and Sobbing are less efficient and may require technical amplification.

Summary: In this study, a method is proposed to calculate the costs of heat distribution in linear and radial district heating networks with low heat densities. The aim is to assist planners and decision-makers in evaluating the suitability of areas for district heating early in the planning process, considering both heat density and individual network design parameters. The study analyzes specific costs and establishes relationships between distribution costs and network expansion. Results indicate that network size, structure, and capital costs significantly influence heat distribution costs.
