Abstract(in English)	To explain acoustic characteristics at the listening point, we measured acoustic coefficients between two ears using an artificial head, and proposed a two spheres model as the artificial head. Difference between the measured and calculated values is explained that the sphere as a torso is replaced by an oblate spheroid. In this paper, we calculate and the diffraction coefficients of large scale oblate spheroid, and measure those of the torso. Compared with the calculated and measured values, we guess the oblate spheroid replaced by the sphere as the torso.
