The use of two types of speech-in-noise (SPIN) assessment, namely digits-in-noise self-tests and open-set, monosyllabic word tests, to assess the SPIN understanding performance of children with cochlear implants (CI) in mainstream and special education, was investigated. The tests' feasibility and reliability and the influence of specific cognitive abilities on their results were studied. The results of 30 children with CIs in mainstream and special education were compared to those of 60 normal-hearing children in elementary school. Results indicate that the digit triplet test (DTT) was feasible for all children tested in this study, as seen by the familiarity of all the digits, the high stability of the test results (<3 dB SNR), and a small measurement error (≤2 dB SNR). Remembering full triplets did not form a problem and results did not show systematic attention loss. For children with CIs, the performance on the DTT was strongly related to the performance on the open-set monosyllabic word-in-noise task. However, small but significant differences were observed in the performance of children with CIs in mainstream and special education on the monosyllabic word test. Both tests showed little influence of cognitive abilities, making them both useful in situations where the bottom-up auditory aspect of SPIN performance needs to be investigated or in situations where sentence-in-noise tests are too challenging.
本研究调查了两种语音干扰（SPIN）评估类型，即数字噪声自测试和开放式单音节词测试，用于评估主流和特殊教育中使用人工耳蜗（CI）的儿童的 SPIN 理解表现。研究了这些测试的可行性和可靠性，以及特定认知能力对其结果的影响。将 30 名主流和特殊教育中接受 CI 的儿童的结果与 60 名小学正常听力儿童的结果进行了比较。结果表明，对于所有接受测试的儿童，三数字测试（DTT）都是可行的，所有数字的熟悉度、测试结果的高度稳定性（<3dB SNR）和较小的测量误差（≤2dB SNR）都表明了这一点。记住完整的三数字并不成问题，结果也没有显示出系统注意力的丧失。对于 CI 儿童，DTT 的表现与开放式单音节词噪声任务的表现密切相关。然而，在主流和特殊教育中接受 CI 的儿童在单音节词测试中的表现存在小但显著的差异。这两个测试对认知能力的影响都很小，因此在需要研究 SPIN 性能的听觉方面或句子噪声测试过于具有挑战性的情况下，这两个测试都很有用。
