Abstract: Control and synthesis of sound source directivity have a significant position in modern acoustics. For this purpose, special sound sources that consist of independent element loudspeaker array are used. Sound source analyzed in this paper is a loudspeaker array in the form of dodecahedron. To generate different directivities, the loudspeaker array is fed independently with a few characteristic sets of signals. Special setup was established for radiation directivity measurements. For analyzing and presenting the results, a MATLAB application is developed. The measured directivities obtained by feeding of some of the loudspeakers with particular signals show interesting patterns of radiation.
