| 摘 要： | 在自由声场中，抵达听者耳膜处的声音信号是随着声源的方向而变化的．由方向所决定的冲激响应被称作与头相关联的冲激响应（ＨＲＩＲ）．利用Ｋａｒｈｕｎｅｎ－Ｌｏｅｖｅ变换对归一化的ＨＲＩＲ作特征抽取．其主分量的特征与先前的许多心理物理实验结果十分吻合．

| Abstract: | Sound arriving at listener's eardrums in free field varies with the source direction. Direction dependent impulse response is called head related impulse response (HRIR). Using Karhunen Loeve transform, spatial features are extracted from the normalized HRIRs. The characteristics of principal components match with the results of some existent phychophysical experiments. |
