The state of the art on measurements of room acoustics parameters is based on an as omnidirectional as possible sound sources. Although these measurements are still the current standard, criticism regarding the standard directivity tolerance and the suitability of omnidirectional sources has emerged in recent years. Currently, research on the suitability of directional sound sources and on the suitability of new descriptors based on directional sources is being carried out by several research groups. This article shows a simulation for emulating directivities of directive sound sources with an array of twelve loudspeakers in a dodecahedron. The state of advance of the implementation of the dodecahedron and the required signal processing is shown
