摘　　要：设计了测量距离可调整的头相关传输函数的实验测量方法,并采用人工头进行近场头相关传输函数的测量,建立了高空间分辨率的近场头相关传输函数数据库,为进一步开展双耳听觉的研究和虚拟听觉的应用提供了数据基础。根据实验数据,初步分析了远、近场情况下,距离、仰角、方位角等参量对头相关传输函数的影响规律。A measurement system was setup to measure the near-field head-related transfer function （HRTF） with range adjustable configuration. High space resolution HRTF measurement was conducted on a mannequin head to build a range-dependent HRTF database, which would be of help for further research works related to spatial hearing. Based on the measurement results, the influences of the distance, azimuth and elevation on the characteristics of HRTF are preliminarily analyzed, ranging from nearto far-field
