对 10 名听力正常的成年人和 8 名植入 Nucleus 人工耳蜗 (CI) 的成年人进行了语音识别评估，这些成年人采用多种不同的信噪比 (SNR) 并采用三种调频 (FM) 系统布置：台式、体戴式和微型直接连接。参与者被要求在课堂环境中重复噪音听力测试（HINT）句子，并确定正确的单词重复百分比。使用桌面声场系统对正常听力和 CI 参与者的表现进行了评估。此外，使用与语音处理器电耦合的两个 FM 系统对 CI 参与者的语音识别进行了评估。当比较桌面声场和No-FM条件时，只有听力正常的听众在噪声中的语音识别方面有显着改善。当比较 CI 听众在三种 FM 条件下的性能时，两个电耦合 FM 系统相对于桌面声场系统在噪声中的语音识别方面具有显着的改进。
Speech recognition was evaluated for ten adults with normal hearing and eight adults with Nucleus cochlear implants (CIs) at several different signal-to-noise ratios (SNRs) and with three frequency modulated (FM) system arrangements: desktop, body worn, and miniature direct connect. Participants were asked to repeat Hearing in Noise Test (HINT) sentences presented with speech noise in a classroom setting and percent correct word repetition was determined. Performance was evaluated for both normal-hearing and CI participants with the desktop soundfield system. In addition, speech recognition for the CI participants was evaluated using two FM systems electrically coupled to their speech processors. When comparing the desktop sound field and the No-FM condition, only the listeners with normal hearing made significant improvements in speech recognition in noise. When comparing the performance across the three FM conditions for the CI listeners, the two electrically coupled FM systems resulted in significantly greater improvements in speech recognition in noise relative to the desktop soundfield system.
