Siebein Fall 2004 Dan Butko, Youngmin Kwon, Koyel Sikdar, Pattra Smitthakorn THE ARCHITECTURE OF DIFFUSION Class Project and Design Competition Designed with precision it (sound) becomes a building material in the creation of space (Bernhard Leitner) INTRODUCTION A sound scape is a way of describing the acoustical landscape of a room, a building or an outdoor space. A sound scape is defined not only by the sounds which are heard in the space, but also by the qualities of those sounds. Sound diffusion is one of the most elusive aspects of sound scapes that are given form by the architectural design features of rooms. There are few formulas to determine how much and what types of diffusion must be used. Most computer programs do not do a very good job of analyzing the effects of diffusion on the sound field in rooms. There are few treatments of how to use diffusion in text books and journal articles. However, diffusion is widely used by architects and acoustical consultants in rooms where critical listening is involved such as recording studios, control rooms, music recital rooms, concert halls and theaters. Diffusion effects what Lothar Cremer (1982) calls the “fine structure of reverberation”. Diffusion consists of basic room shapes, sculpted forms and textured surfaces that scatter sound in many directions. Most of the materials that diffuse sound have very distinctive architectural forms. They are large curved surfaces, highly textured woods, metals, frg, glasses and plastics, angled and faceted forms made of wood, steel, plaster or glass and a variety of other shapes and materials. The study of diffusion in rooms is inherently architectural because of the intimate relationship between the visual form of diffusing elements and their acoustical function. Perhaps with no other acoustical function is the relationship between visual space and
