虽然有相当多的证据表明，双侧人工耳蜗（CI）用户的声音定位能力主要依赖于耳间水平差（ILD）线索，只有其次，如果有的话，耳间时间差（ITD）线索，这一证据在很大程度上是间接的。本研究使用头部相关传递函数（HRTF）独立操作ITD和ILD线索，并直接测量其对双侧CI用户定位能力的贡献。结果显示，强烈依赖ILD线索，但一些CI用户也利用ITD线索。结果还表明ITD和ILD线索之间存在复杂的相互作用。(C)2010年美国声学学会
While considerable evidence suggests that bilateral cochlear implant (CI) users' sound localization abilities rely primarily on interaural level difference (ILD) cues, and only secondarily, if at all, on interaural time difference (ITD) cues, this evidence has largely been indirect. This study used head-related transfer functions (HRTFs) to independently manipulate ITD and ILD cues and directly measure their contribution to bilateral CI users' localization abilities. The results revealed a strong reliance on ILD cues, but some CI users also made use of ITD cues. The results also suggest a complex interaction between ITD and ILD cues.
