Variable Geometry Acoustical Domes - Towards an architectural design method based on spatial sound behavior Domes acoustiques à géométrie variable - Vers une nouvelle méthode de conception architecturale basée sur la propagation du son dans l'espace En Fr

Résumé En Fr

Traditionally, domes are seen as architectural elements, which allow for the covering of large spaces by the structural assembly of discrete components. I recently developed a new kind of dome, which does not relate to structure but instead to acoustics. In collaboration with an acoustician and a programmer, I have been developing techniques to simulate soundfields of a given space and construct domes based on these fields. Suspended from the ceiling of an existing space, the Acoustical Dome is an experimental device, whose geometry allows for the variation of position in space and an adjustment of form to modify the acoustical behavior of the hall.Established in 1992, Thresholds is the annual peer-reviewed journal produced by the MIT Department of Architecture. Each independently themed issue features content from leading scholars and practitioners in the fields of architecture, art, and culture. The Thresholds advisory board, composed of internationally recognized figures in various fields of art culture, drives the development of each issue through intellectual support and the pursuit of high-quality submissions from fine arts, design, graphics, media arts and sciences, film, photography, and more.

Traditionnellement, les dômes sont considérés comme des éléments architecturaux, qui permettent de couvrir de grands espaces par l'assemblage structurel de composants discrets. Cet article relate les travaux de David Serero à la Villa Medici, où il a développé un nouveau type de dôme, qui ne concerne pas la structure mais plutôt l'acoustique. En collaboration avec un acousticien et un programmeur, il a développé des techniques pour simuler les champs sonores d'un espace donné et construire des dômes à partir de ces champs. Suspendu au plafond d'un espace existant, le Dôme Acoustique est un dispositif expérimental, dont la géométrie permet la variation de position dans l'espace et un ajustement de forme pour modifier le comportement acoustique de la salle.
