In musical perception, a proportion of the reflected sound energy arriving at the ear is not consciously perceived. Investigations by Wettschurek in the 1970s showed the detectability to be dependent on the overall loudness and direction of arrival of reflected sound. The relationship Wettschurek found between reflection detectability, listening level, and direction of arrival correlates well with the subjective progression of spatial response during a musical crescendo: from frontal at pianissimo, through increasing apparent source width, to a fully present room acoustic at forte. “Dynamic spatial responsiveness” was mentioned in some of the earliest psychoacoustics research and recent work indicates that it is a key factor in acoustical preference. This article describes measurements of perception thresholds made using a binaural virtual acoustics system—these show good agreement with Wettschurek’s results. The perception measurements indicate that the subjective effect of reflections varies with overall listening level, even when the reflection level, delay, and direction relative to the direct sound are maintained. Reflections which are perceptually fused with the source may at louder overall listening levels become allocated to the room presence. An algorithm has been developed to visualize dynamic spatial responsiveness—i.e., which aspects of a three-dimensional (3D) Room Impulse Response would be detectable at different dynamic levels—and has been applied to measured concert hall impulse responses.

The article is focused on the analysis of the Zaryadye Concert Hall building in Moscow in terms of the significance of artificial lighting for the creation of the imagery and perception of this facility within the typology of entertainment music-oriented buildings. Through the example of modern places of entertainment, the author reveals a number of formal features (typological attributes), which, being common to buildings of this function, constitute the basis of their image and become obvious due to the realized lighting concept. The interpretation of these attributes in the interaction of architectural planning and lighting concepts in the Zaryadye Concert Hall is traced. In conclusion, the distinctive features of the building under consideration are determined. At the same time, they reflect a new understanding of concert halls as a building type, the changes related to the overall development of architecture, as well as the elements of the individual architectural language.

In this paper, we discuss the integration of 2-D video actors into 3-D augmentedreality (AR) systems. In the context of our research on narrative forms for AR, we have found ourselves needing highly expressive content that is most easily created by human actors. We discuss the feasibility and utility of using video actors in an AR situation and then present our Video Actor Framework (including the VideoActor editor and the Video3D Java package) for easily integrating 2-D videos of actors into Java 3D, an object-oriented 3-D graphics programming environment. The framework is based on the idea of supporting tight spatial and temporal synchronization between the content of the video and the rest of the 3-D world. We present a number of illustrative examples that demonstrate the utility of the toolkit and editor. We close with a discussion and example of our recent work implementing these ideas in Macromedia Director, a popular multimedia production tool.

Important Quality

Ob Großraumbüros, Konzerthallen oder Auditorien – bau- und raumakustische Eigenschaften stellen nicht nur ein wichtiges Qualitätsmerkmal für Gebäude dar, sie bestimmen auch maßgeblich das Wohlgefühl der Nutzer. Wo bisherige Maßnahmen zum Schallschutz mit dem Wunsch nach einer idealen Temperierung von Gebäuden als unvereinbar galten, stellt die Weiss Doppelbodensysteme GmbH, Traditionsunternehmen aus dem schwäbischen Lindach, ein Produkt vor, welches es ermöglicht, beide Kriterien miteinander zu vereinen: Den Akustik-Doppelboden.   Summary Whether open-plan offices, concert halls or auditoriums – building and room acoustics not only represent an important quality feature for buildings, they also significantly determine the well-being of the users. Where previous measures for sound insulation were considered incompatible with the desire for an ideal temperature control of buildings, Weiss Doppelbodensysteme GmbH, a traditional company from the Swabian town of Lindach, presents a product that makes it possible to combine both criteria: the acoustic double floor.

What did the Edwardians know about Spain, and what was that knowledge worth? The Edwardians and the Making of a Modern Spanish Obsession draws on a vast store of largely unstudied primary source material to investigate Spain’s place in the turn-of-the-century British popular imagination. Set against a background of unprecedented emotional, economic and industrial investment in Spain, the book traces the extraordinary transformation that took place in British knowledge about the country and its diverse regions, languages and cultures between the tercentenary of the Spanish Armada in 1888 and the outbreak of World War I twenty-six years later. This empirically-grounded cultural and material history reveals how, for almost three decades, Anglo-Spanish connections, their history and culture were more visible, more colourfully represented, and more enthusiastically discussed in Britain’s newspapers, concert halls, council meetings and schoolrooms, than ever before. It shows how the expansion of education, travel, and publishing created unprecedented opportunities for ordinary British people not only to visit the country, but to see the work of Spanish and Spanish-inspired artists and performers in British galleries, theatres and exhibitions. It explores the work of novelists, travel writers, journalists, scholars, artists and performers to argue that the Edwardian knowledge of Spain was more extensive, more complex and more diverse than we have imagined.

The twenty-seventh annual NEMLA convention will be held in Montreal from 19 to 20 April 1996 at the Hotel du Parc. In the heart of vibrant Montreal, Hotel du Parc is located at the foot of Mount Royal, within walking distance of world-class galleries, museums, and concert halls, exuberant nightlife and gourmet dining on trendy Saint-Laurent and Saint-Denis Streets, and relaxed sidewalk cafes on Prince Arthur's bustling pedestrian mall. McGill University will be the host institution, and Nicole Brossard will be the Friday night keynote speaker.
