Abstract: Three HRTF databases were set up for investigating the relationship between distance and interaural cues (including ITD and IID). The first database is from the calculated spherical head model, the second is the distance-dependent HRTF database for KEMAR manikin, and the third is the distance-dependent HRTF database for KEMAR manikin without pinnae. The results using the three databases confirm that distance play an important role in affecting the interaural cues in proximal region.

Key words: interaural cues, spherical head model, HRTFs, distal region, proximal region

摘要： 基于头传递相关函数库开展对双耳时间差和强度差与声源距离线索关联的研究。采用三组头相关传递函数库(基于KEMAR人工头的PKU&IOA HRTFs 库、基于 KEMAR 人工头但不包括耳廓的PKU&IOA HATFs 库和基于球模型的HRTF 库) , 研究了距离对双耳定位线索的影响( 包括 ITD 和 IID) 。分析结果表明, 距离在双耳定位中有非常重要的作用, 尤其在近场环境下, 距离对双耳线索的影响是明显的。
