中文摘要：

采用脉冲发生器作为点声源，通过控制水平角、仰角和距离等三维空间参数，测量了一种高空间分辨率的结构化头相关传递函数，其中包括头传递函数、头和耳廓传递函数以及头和躯干传递函数。基于测得的结构化头相关传递函数，分析了各结构对头相关传递函数的影响，并结合本研究测得的结构化头相关传递函数和2009年测得的完整头相关传递函数，基于两种加性法则计算分析了耳廓传递函数，分析结果表明两种方法得到的耳廓相关传递函数具有高相关度，验证了头相关传递函数是由头、躯干和耳廓的传递函数叠加而成的合理性。

英文摘要：

The structural head-related transfer functions with high spatial resolution are meas- ured using spark gap generator, which include head transfer function, head and pinna transfer function and head and torso transfer function. Based on the measured structural transfer func- tions, the effects of head, pinnae and torso on the total head-related transfer function are ana- lyzed. Using the measured structural head-related transfer functions and the total head-related transfer functions, the pinna transfer functions are calculated using two different methods. The results show that the two pinna transfer functions are highly correlated in frequency do- main. That means, under some conditions, the head-related transfer function can be seen as the summation of head transfer function, torso transfer function and pinna transfer function.
