Users of a cochlear implant and contralateral hearing aid are sensitive to interaural level differences (ILDs). However, when using their clinical devices, most of these subjects cannot use ILD cues for localization in the horizontal plane. This is partly due to a lack of high-frequency residual hearing in the acoustically stimulated ear. Using acoustic simulations of a cochlear implant and hearing loss, it is shown that localization performance can be improved by up to 14 degrees rms error relative to 48 degrees rms error for broadband noise by artificially introducing ILD cues in the low frequencies. The algorithm that was used for ILD introduction is described.
使用人工方法在低频引入强度差线索可以将人工耳蜗植入体和听力损失的声模拟的定位性能提高 14 度均方根误差，相比宽带噪声的 48 度均方根误差，这与高频残余听力在受声刺激耳中的缺失部分相关。该文描述了引入强度差线索的算法。植入体和对侧助听器使用者对耳间强度差（ILDs）敏感。然而，当使用他们的临床设备时，这些受试者中的大多数不能使用 ILD 线索进行水平平面定位。这部分是由于在受声刺激耳中缺乏高频残余听力。
