Balconies are normally used in large auditoria such as concert halls or opera houses, to increase seating capacity or to give better view for a distinguished group of the audience. When ray-tracing based computer models are applied to study the acoustical quality of these auditoria, the alteration of the sound field due to balcony fronts is normally unobservable, because of the relative small size of the balcony fronts in the auditorium. Furthermore, most diffuse reflection ray-tracing methods are not based on direct wave acoustics but on an approximation of the scattering effect. In practice, experience shows that balcony fronts give additional warmth to music. This effect is more prominent when singers perform in traditional horseshoe shaped opera houses with multi-levels balconies. This paper describes modelling of scattering from balcony fronts using a theoretical wave approach, in which the incident wave front is not plane but spherical. A computer simulation illustrates the scattering of sound that takes place when the wavefront impinges on the surface of the balcony fronts.

The Way

Investigates the way that Spain, Spanish culture and Spanish identity were represented on British stages, concert halls and other public and private spaces. Considers the figure of the Spanish dancer as an avatar for the simultaneous decline and persistence of French-mediated Romantic stereotypes in the British imagination. Explores the opportunities for British people to ‘embody’ Spanishness, through performance, fancy dress, and the role of music hall parodies in domesticating Spanish otherness.

Using Data

The role of spatial design in music has become more prominent in recent years, mostly because of the affordability of powerful software and hardware tools. Although spatial audio tools are widely used nowadays in studios and concert halls, there are only few examples of robust and comfortable wearable sound systems with a suitable acoustic response. A wireless body-worn loudspeaker prototype featuring original costume elements, a hybrid full-range loudspeaker array and an improved acoustic response was designed and implemented. The size, shape and acoustic performance of the prototype was optimised using data gathered from anechoic measurements and interviews with performers and audiences. Future developments of this project will consider the implementation of an extended multi-channel performance platform to explore sonic and spatial relationships created by several wearable devices on stage synchronised with a multi-loudspeaker diffusion system.

PROBLEM: There is no consensus regarding the best approach to select patients for septoplasty. Patient dissatisfaction after septoplasty implies that clinical examination alone is inadequate to detect a clinically relevant nasal septal deviation (NSD). Objective testing provides an in-depth analysis of nasal obstruction and its underlying anatomic causes but it is effort consuming, requires training and it is not widely available. AIM: We studied the role of bilateral simultaneous nasal spirometry (BSNS) in the preoperative selection of patients for septoplasty. PATIENTS, SUBJECTS AND METHODS: Thirty patients with nasal obstruction and NSD were assessed by subjective measures and BSNS before and after septoplasty. The decongested nasal partitioning ratio (NPR) was used as a measure of the degree of NSD. Thirty healthy controls were recruited for providing a normal range of NPR values. RESULTS: All patients were subjectively improved after septoplasty but only those with NPR out of the normal limits had a significant reduction of NPR. Patients with unilateral symptoms and NPR beyond normal limits were also able to identify the more obstructed side preoperatively. For this group of patients, physicians were able to identify the convex side of NSD preoperatively. No correlation between subjective measures of nasal obstruction or airflow asymmetry and NPR was observed. CONCLUSION: BSNS is a rapid, easily interpretable, noninvasive technique, which identifies patients with large NSDs who, irrespective of concomitant mucosal factors of nasal obstruction, warrant septoplasty. BSNS is not applicable in cases with a septal perforation or an S type septal deviation, it cannot detect an insufficient nasal valve and it does not substitute rhinomanometry or acoustic rhinometry.

Requiem Mass

The 13th century Latin hymn, Dies Irae, is one of the better-known Roman Catholic liturgical sequences, famous for its seemingly-dark portrayal of the Day of Judgment (“Day of Wrath”). Once a staple element of the Requiem Mass, this text has now been relegated to relative obscurity, finding life only in concert halls, where grandiose musical settings of Mozart’s & Verdi’s “Requiem Mass” are performed. In its absence, the Dies Irae is now synonymous with a bleak, medieval theology fixated on death and judgement. However, upon deeper examination, it seems that the “Day of Wrath” can also be read as a “Day of Mercy.” Sorrow for past transgressions and preoccupation with eternal hell constitute only one element of the hymn. Far from being focused on sin and death, the Dies Irae also establishes the vital connection between Christ’s mercy for sinners and the mercy each Christian is called to share with one another. This is seen through the numerous Scriptural allusions which fill the hymn, including those referencing that ‘final day’, when Christ is said to “judge the living and the dead.” In pleading to be on the right side during the separation between the metaphorical “sheep and goats,” the author acknowledges the significance of Christ and His command to love the “least of these” on the Day of Judgement (Matthew 25:40). The Dies Irae contains both a call for mercy and a call to mercy, the latter of which distinguishes itself as the litmus test of salvation.

Compositional Styles

Music is universally a key part of life, with a diversity of styles and usage from love songs to warfare and religion. The variations are immense, and always changing. This introduction has a historical outline, with a rapid overview of early instruments and music. Music developed partly from a gradual relaxation of religious control of what was acceptable. The Renaissance in art and literature contributed, but they require language and knowledge of the symbolisms. Music has none of these restrictions, and our responses are totally personal. There has been a major role of scientific inputs into instruments, concert halls, distribution of music via printing and notation, plus the electronics of recorded music and broadcasting. These factors altered compositional styles. The following chapters will expand on these highly diverse and numerous scientific and technological features and their musical consequences.

And Performance

Prior literature paints an incoherent picture on the relationship between team diversity and performance. The current article investigates circumstances under which demographic diversity (gender and nationality) facilitates performance. Based on the categorization–elaboration model, we build a theoretical framework to demonstrate the crucial role of team learning and efficacy as mediators, and team identification as a moderator to understand how and when demographic diversity facilitates team performance. In a cross-sectional study among 72 project teams, data were collected from multiple sources (self-reports, database, and performance assessments) to obtain objective and subjective indices of team diversity and performance. Results from a multigroup structural equation model showed that team diversity facilitated performance for teams with a strong, but not a weak, collective team identity. Second, team diversity facilitated performance through increased team learning and team efficacy only for teams with a strong team identity. Finally, multisource data revealed a different pattern of results for objective and subjective measures. The objective diversity index seemed a more powerful predictor of performance compared with the subjective index, particularly for strongly identifying teams. These findings provide valuable insight for increasingly diversifying organizations, on the circumstances under which team diversity’s potential flourishes. Moreover, it underlines the importance of data triangulation as objective and subjective measures of diversity are conceptually different and show incoherent empirical findings in the diversity–performance link across extant literature.
