Bilateral cochlear implant users often have difficulty fusing sounds from the two ears into a single percept. However, measuring fusion can be difficult, particularly with cochlear implant users who may have no reference for a fully fused percept. As a first step to address this, this study examined how localization performance of normal hearing subjects relates to binaural fusion. The stimuli were vocoded speech tokens with various interaural mismatches. The results reveal that the percentage of stimuli perceived as fused was correlated with localization performance, suggesting that changes in localization performance can serve as an indicator for binaural fusion changes.
双侧人工耳蜗使用者常常难以将来自双耳的声音融合成单一的感知。然而，测量融合情况可能很困难，尤其是对于那些可能没有完全融合感知作为参考的人工耳蜗使用者。作为解决这一问题的第一步，本研究考察了正常听力受试者的定位表现与双耳融合之间的关系。刺激物是具有各种双耳失配的声码语音片段。结果表明，被感知为融合的刺激物百分比与定位表现相关，这表明定位表现的变化可以作为双耳融合变化的一个指标。
