Third-order synthetic sentences were aligned to make them suitable for dichotic presentation. These dichotic sentence materials were then administered to 14 normal listeners and 48 hearing-impaired subjects to determine the influence of peripheral hearing loss on test performance. Results suggest that the Dichotic Sentence Identification test is resistant to the influence of peripheral hearing loss until the pure-tone average of 500, 1000, and 2000 Hz exceeds approximately 50 dB. Beyond this level, degree of peripheral hearing loss limits its value for detecting central auditory disorder. Data are also provided on six persons with either confirmed or suspected lesions involving retrocochlear structures.
对三阶合成句子进行了调整，使其适合用于双耳分听呈现。然后将这些双耳分听句子材料施用于14名正常听力者和48名听力受损受试者，以确定外周听力损失对测试表现的影响。结果表明，在500、1000和2000赫兹的纯音平均值超过约50分贝之前，双耳分听句子识别测试对外周听力损失的影响具有抗性。超过这个水平，外周听力损失的程度会限制其在检测中枢听觉障碍方面的价值。还提供了关于6名患有已确诊或疑似蜗后结构病变患者的数据。
