| 摘 要： | 提出了一种利用双扬声器的头相关传递函数(HRTF)动态测量方法,在减轻测试条件要求的同时有效提高了测试效率.首先利用双扬声器阵列播放不相关信号,通过短时时延估计来实现人头尺寸的获取及头部运动姿态的实时跟踪;其次,在短时间内满足近似线性时不变系统的条件下,实现HRTF的多点同时测量及所需空间区域的连续测量.与FASTRA...

| Abstract: | A dynamic Head-related Transfer Function(HRTF) measurement method using a dual-loudspeaker array is presented,which reduces measuring requirements and increases the efficiency as well.First,the dual-loudspeaker array emits uncorrelated signals,while head size and head motion are obtained through short-time time-delay estimation.Second,in the approximation of linear time-invariant(LTI) within the test time,multi-point continuous HRTF measurement is achieved.The experimental results show the validity of the proposed method compared with FASTRAK head tracking system. |
