N2 - Auditory display techniques require subjective evaluations of the virtual sound field to determine the accuracy of a reproduced sound with respect to a listener's perception of spatial information. To synthesize a physically accurate sound field, local sound field synthesis limits the controlled area inside the loudspeaker array. The size and position of the controlled area affects the accuracy of the synthesis. In this study, we investigate the sound localization accuracies at different positions inside a 2Dimensional loudspeaker array by measurement of the interaural level differences in an anechoic chamber. The results show that the sound localization of the local sound field synthesis was more accurate than the conventional wave field synthesis, if a suitable parametrization of local listening area is chosen.
