Abstract

This study aimed to compare the Hebrew version of the digits-in-noise (DIN) thresholds among cochlear implant (CI) users and their normal-hearing (NH) counterparts, explore the influence of age on these thresholds, examine the effects of early auditory exposure versus its absence on DIN threshold, and assess the correlation between DIN thresholds and other speech perception tests. A total of 13 children with CI (aged 5.5–11 years), 15 pre-lingual CI users (aged 14–30 years), and 15 post-lingual CI users (aged 22–77 years), and their age-matched NH controls (n = 45) participated in the study. Speech perception tasks, including the DIN test, one-syllable word test, and sentence identification tasks in various auditory conditions, served as the main outcome measures. The results indicated that CI users exhibited higher speech reception thresholds in noise across all age groups compared to NH peers, with no significant difference between pre-lingual and post-lingual CI users. Significant differences were also observed in monosyllabic word and sentence accuracy in both quiet and noise conditions between CI and NH groups. Furthermore, correlations were observed between the DIN and other speech perception tests. The study concludes that CI users require a notably higher signal-to-noise ratio to discern digits in noise, underscoring the DIN test’s utility in assessing speech recognition capabilities in CI users while emphasizing the need for a comprehensive test battery to fully gauge their speech perception abilities.

人工耳蜗使用者和正常听力者的希伯来语噪声数字（DIN）测试

本研究旨在比较希伯来语版噪声中数字（DIN）阈值在人工耳蜗（CI）用户和正常听力（NH）用户中的应用情况，探讨年龄对这些阈值的影响，研究早期听觉接触与不接触对 DIN阈值的影响，并评估 DIN阈值与其他言语感知测试之间的相关性。共有 13 名 CI 儿童（5.5-11 岁）、15 名语言前 CI 使用者（14-30 岁）、15 名语言后 CI 使用者（22-77 岁）及其年龄匹配的 NH 对照组（n = 45）参加了研究。语音感知任务包括 DIN 测试、单音节词测试和各种听觉条件下的句子识别任务，作为主要结果测量指标。结果表明，与 NH 同龄人相比，所有年龄组的 CI 使用者在噪声中都表现出更高的语音接收阈值，而语言前和语言后 CI 使用者之间没有显著差异。在安静和噪音条件下，CI 组和 NH 组在单音节词和句子的准确性方面也存在显著差异。此外，还观察到 DIN 与其他言语感知测试之间存在相关性。研究得出结论，CI 用户需要更高的信噪比才能在噪声中辨别数字，这突出了 DIN 测试在评估 CI 用户语音识别能力方面的实用性，同时也强调了需要一个全面的测试组合来全面衡量他们的语音感知能力。
