Abstract(in English) | As one of 3 components of HRTF, the diffraction coefficients of an artificial head removing pinna and closed ear canal are measured. Peaks and dips of the frequency characteristics of the diffraction coefficients appear at nearly equal frequencies regardless of the azimuth angle of the incident sound wave. In order to clarify this, the diffraction coefficients of the artificial head are calculated with an oblate spheroid model in which the head and the torso are oblate spheroids. Compared with 2 sphere model, the measured value agrees better with the values calculated with the oblate spheroid model. |
