In order to find a possible correlation of objective parameters and subjective descriptors of the acoustic of theatres, auditoria or music hall, and so to perform meaningful listening tests, we need to find a reliable 3D audio system which should give the correct perception of the distances, a good localization all around the listener and a natural sense of realism. For this purpose a Stereo Dipole system and an Ambisonic system were installed in a listening room at La Casa Della Musica (Parma, Italy). Listening tests were carried out for evaluating the localization performances of the two systems.
