AB  - In this paper a dodecahedron with high powered loudspeakers is presented. The source is designed to allow high SPL with very low distortion. By comparing the prototype with a reference sound source, the high SPL dodecahedron show a flat frequency response over the 80 ÷ 5000 Hz one third octave bands, enough to meet all the ISO 3382 criteria. Laboratory measurements have been performed to test the performances and the robustness of the dodecahedron using different techniques at different sound pressure levels and background noises. The prototype allows a good signal-to-noise ratio of the impulse response also when 75 dB of stationary noise is added during the measurements.
