这项对现有数据的回顾性分析来自一个以人群为基础的队列的957名成员，他们参加了先前的中枢性听觉功能障碍患病率研究。将三种强度水平的单词识别分数（WRS）与基于清晰度指数（AI）和Thornton-Raffin 95%临界差异的预测分数进行比较。在112名（11.7%）参与者中，一个或多个单词识别分数明显低于预测分数，我们认为这是可能的听神经病的微妙迹象。相比之下，使用语音平衡单词列表的性能强度函数翻转的人中只有3人（0.3%）发现了耳蜗后功能障碍的经典体征，使用Yellin等人（1989）的指南的人中有2人（0.2%），使用AI（x 100）和WRS之间的20点差异的人中有54人（5.6%）。可能的听神经病变的细微体征比经典体征更常见。建议将几个高呈现水平的WRS与AI进行比较，作为筛选细微神经病变的方法。WRS低于基于AI的Thornton-Raffin 95%临界差异的老年听众应考虑进一步测试与年龄相关的听神经病。
This retrospective analysis of existing data was derived from 957 members of a population-based cohort who participated in a prior study of the prevalence of central auditory dysfunction. Word recognition scores (WRS) at three intensity levels were compared to predicted scores based on the Articulation Index (AI) and the Thornton-Raffin 95 percent critical differences. In 112 (11.7 percent) participants, one or more word recognition scores were significantly below the predicted score, which we consider a subtle sign of possible auditory neuropathy. In contrast, classic signs of retrocochlear dysfunction were found in only three people (0.3 percent) using rollover of the performance-intensity function for phonetically balanced word lists, in two (0.2 percent) people using the guideline of Yellin et al (1989), and in 54 people (5.6%) using a 20-point difference between the AI (x 100) and the WRS. Subtle signs of possible auditory neuropathy were more frequent than the classic signs. Comparing WRS at several high presentation levels to the AI is suggested as a method to screen for subtle neuropathy. Elderly listeners whose WRS fall below the Thornton-Raffin 95 percent critical difference based on AI should be considered for further testing for age-related auditory neuropathy.
