Abstract

Background/objectives: Advances in cochlear implant (CI) technology have led to the expansion of the implantation criteria. As a result, more CI candidates may have greater residual hearing in one or two ears. Many of these candidates will perform better with a CI in one ear and a hearing aid (HA) in the other ear, the so-called bimodal solution. The bimodal solution often requires patients to switch to HAs that are compatible with the CI. However, this can be a challenging decision, not least because it remains unclear whether this impacts hearing performance. Our aim is to determine whether speech perception in noise remains unchanged or improves with new replacement HAs compared to original HAs in CI candidates with residual hearing.

Methods: Fifty bilateral HA users (mean age 63.4; range 23-82) referred for CI were recruited. All participants received new replacement HAs. The new HAs were optimally fitted and verified using Real Ear Measurement (REM). Participants were tested with the Hearing in Noise Test (HINT), which aimed at determining the signal-to-noise ratio (SNR) required for a 70% correct word recognition score at a speech sound pressure level (SPL) of 65 dB. HINT testing was performed with both their original and new replacement HAs. During HINT, pupillometry was used to control for task engagement.

Results: Replacing the original HAs with new replacement HAs after one month was not statistically significant with a mean change of SRT70 by -1.90 (95% CI: -4.69;0.89, p = 0.182) dB SNR.

Conclusions: New replacement HAs do not impact speech perception scores in CI candidates prior to the decision of cochlear implantation.

用噪声听力测试和瞳孔测量法评价人工耳蜗候选者的替代助听器。

背景/目的：人工耳蜗技术的进步导致人工耳蜗植入标准的扩大。因此，更多的CI候选者可能在一只或两只耳朵中有更大的残余听力。这些候选人中的许多人在一只耳朵上戴CI，另一只耳朵上戴助听器（HA），即所谓的双峰解决方案，表现会更好。双峰解决方案通常需要患者切换到与CI兼容的ha。然而，这可能是一个具有挑战性的决定，尤其是因为尚不清楚这是否会影响听力表现。我们的目的是确定与具有残余听力的CI候选人的原始HAs相比，新的替代HAs是否在噪声中的语音感知保持不变或有所改善。方法：50例双侧HA使用者(平均年龄63.4岁；范围23-82)被纳入CI。所有参与者都获得了新的替换ha。新的HAs通过实耳测量（REM）进行了最佳安装和验证。参与者接受了噪声听力测试（HINT），该测试旨在确定在语音声压级（SPL）为65 dB时，正确识别70%单词得分所需的信噪比（SNR）。对原ha和新ha进行了HINT测试。在HINT过程中，瞳孔测量法用于控制任务参与。结果：1个月后用新ha替换原ha无统计学意义，SRT70平均变化为-1.90 dB信噪比（95% CI: -4.69;0.89, p = 0.182）。结论：在决定人工耳蜗植入术之前，新的替代人工耳蜗不会影响CI患者的语音感知评分。
