为了研究认知功能和助听器使用之间的可能关系，进行了两个实验。在实验1中，72名首次使用助听器的人在戴助听器和不戴助听器的情况下进行了噪声中的语音识别测试(Hagerman语句测试)。通过工作记忆(阅读广度测试)和言语信息处理速度测试来评估认知功能。结果表明，在控制了年龄和听力损失后，无论戴助听器还是不戴助听器，在噪声中的认知表现和语音识别的测量之间都存在显著的相关性。高认知表现与高语音识别任务中的高表现相关。在实验2.17中，工作记忆容量高或低的首次助听器用户测试了一种实验助听器，该助听器根据是否检测到语音而对声音进行不同的处理。结果表明，高工作记忆容量的被试比低工作记忆容量的被试更善于识别和报告辅助剂的具体加工效果。这可能会影响到如何在研究背景下解释报告的结果，如何制定个人的康复需求，以及如何监督助听器控制。总之，应该仔细关注听者的认知状态，因为它可能会对他们使用助听器的能力产生重大影响。
Two experiments were conducted to investigate possible relationships between cognitive function and hearing aid use. In Experiment 1, 72 first-time hearing aid users were tested for speech recognition in noise (Hagerman sentence test) with and without hearing aids. Cognitive function was assessed by tests of working memory (reading span test) and verbal information-processing speed. The results indicate that, after controlling for age and hearing loss, significant correlations exist between the measures of cognitive performance and speech recognition in noise, both with and without hearing aids. High cognitive performance was associated with high performance in the speech recognition task. In Experiment 2. 17 first-time hearing aid users with either high or low working-memory capacity tested an experimental hearing aid which processed the sound differently depending on whether or not speech was detected. The results revealed that those with high working-memory capacity were better than those with low capacity at identifying and reporting the specific processing effects of the aid. This may have implications for how reported results should be interpreted in a research context, how a person's rehabilitation needs are formulated, and how hearing aid controls should be supervised. In conclusion, careful attention should be paid to the cognitive status of listeners, as it can have a significant influence on their ability to utilize their hearing aids.
