有证据表明，认知能力可预测从非线性数字助听器的特定压缩释放设置中获益的能力。以前的研究已经调查了各种认知测试的预测价值，在噪声中使用压缩释放设置，已经经历了一段时间的辅助语音识别。然而，尚未研究使用新设置的认知测试的预测价值，用户还没有机会习惯。在本研究中，我们比较了两个认知测试的预测值，阅读广度和字母监测，在32个习惯性听力仪器使用者使用新的压缩释放设置的噪声中的辅助语音识别。我们发现，阅读广度是一个强有力的预测语音识别噪声与新的压缩释放设置。这一结果概括了以前的研究结果，经验丰富的测试设置新的测试设置，在本研究中使用的噪声测试，Hagerman句子和提示字母监测的语音识别，另一方面，没有发现是一个强大的预测噪声中的语音识别与新的压缩释放设置。
Evidence suggests that cognitive capacity predicts the ability to benefit from specific compression release settings in non-linear digital hearing instruments. Previous studies have investigated the predictive value of various cognitive tests in relation to aided speech recognition in noise using compression release settings that have been experienced for a certain period. However, the predictive value of cognitive tests with new settings, to which the user has not had the opportunity to become accustomed, has not been studied. In the present study, we compare the predictive values of two cognitive tests, reading span and letter monitoring, in relation to aided speech recognition in noise for 32 habitual hearing instrument users using new compression release settings. We found that reading span was a strong predictor of speech recognition in noise with new compression release settings. This result generalizes previous findings for experienced test settings to new test settings, for both speech recognition in noise tests used in the present study, Hagerman sentences and HINT Letter monitoring, on the other hand, was not found to be a strong predictor of speech recognition in noise with new compression release settings.
