擬似頭を頭部球体・胸部球体・耳介円板の3要素に分解し,各要素からの散乱波は別の要素の入射波と考え、散乱・入射を繰り返し行う重ね合わせ法で,耳孔入口の音圧と自由音場の音圧比(HRTF)を求める.散乱・入射の繰り返し形態は,球体間(球体単独も含む),円板単独,球体・円板,円板・球体の4パターンに分類して検討する.擬似頭SAMRAIの測定値との比較より,計算方法の確認をおこなう. |

The artificial head is decomposed into three elements: the head sphere, the torso sphere, and the pinna disc. The scattered waves from each element are considered to be the incident waves of another element, and the sound pressure ratio (HRTF) at the entrance of the ear canal to the sound pressure in the free sound field is obtained by the superposition method in which scattering and incidence are repeated. The pattern of repeated scattering and incidence is classified into four patterns: between spheres (including single sphere), single disk, sphere/disk, and disk/sphere. The calculation method is confirmed by comparing with the measured values of the artificial head SAMRAI. |
