Some builders of acoustics sources produce dodecahedral loudspeakers. These sources have the characteristic to be omni-directional. This is one of important requirements for the sound source thatcan be create from various spherical polyhedrons. The paper: CHIN. PHYS. LETT. Vol. 27, No. 12 (2010) 124302,
Directivity of Spherical Polyhedron Sound Source Used in Near-Field HRTF Measurements, by YU Guang-Zheng, XIE Bo-Sun, RAO Dan, is investigating the directivities of the spherical tetrahedron, hexahedron and dodecahedron sound sources.
