Wave III of the BAEP was analysed both with 3-channel Lissajous' trajectory (3-CLT) and a dipole localization method. The experiments were performed on 5 normally hearing subjects. The dipole analysis used an iterative algorithm assuming a spherical head model and homogeneous media. 3-CLT planar analysis was performed with a laboratory system. The parameters of plane C (azimuth and elevation) corresponding to wave III and those of the equivalent dipole showed a similar orientation of the plane and the dipole. This result is in agreement with previous investigations and confirms the interest of 3-CLT in far-field analysis and, at the same time, validates the dipole localization model used in this study, at least for BAEP analysis.
采用三通道利萨如图形轨迹（3-CLT）和偶极子定位方法对脑干听觉诱发电位（BAEP）的Ⅲ波进行了分析。实验在5名听力正常的受试者身上进行。偶极子分析采用了一种假设头部为球形模型且介质均匀的迭代算法。3-CLT平面分析是使用实验室系统进行的。与Ⅲ波对应的平面C的参数（方位角和仰角）以及等效偶极子的参数显示，平面和偶极子具有相似的方向。这一结果与先前的研究一致，证实了3-CLT在远场分析中的价值，同时也验证了本研究中使用的偶极子定位模型，至少对于BAEP分析是有效的。
