| Résumé |
The use of acoustical scale models has been replaced for the most part by computational models and numerical simulations for room acoustic studies as well as artificial reverberation units. There remains however a number of acoustical phenomena which are difficult to address with computer simulations, such as coupled volumes, diffraction, and complex scattering, due to the computational complexity and/or calculation time necessary for addressing such acoustical wave phenomena on the scale of room acoustical problems, even small rooms. This paper presents a pilot study of a rather unique artistic architectural structure consisting of a self-supporting construction composed of small stacked linear elements. Acoustically, the structure combines modal behavior, concave forms, and very regular scattering patterns. An example scale model has been constructed and studied in order to separate different construction features and their associated acoustics effects. In an attempt to explore the interest of the specific acoustic for musical performance, a computational platform was created to utilize the scale model as a physical convolution reverberation unit for musical performance. |
