本研究的目的是：（1）调查语音材料对响度不适水平（LDL）的影响； (2) 评估三项 LDL 试验的会话内稳定性； (3) 检查语音 LDL 与纯音阈值和听音阈值之间的关系。九十六名患有轻度至中度感音神经性听力损失的成年人接受了测试。调查结果显示，五种市售演讲材料之间几乎没有差异。因此，得出的结论是，在比较平均 LDL 数据时，语音材料的差异并不构成研究之间变异的主要来源。然而，群体平均值可能会掩盖由不同语音材料导致的 LDL 的显着个体差异。研究发现，具有相似阈值的听众之间存在相当大的 LDL 变异性，这表明预测错误率极高。
This study was undertaken to: (1) investigate the effects of speech materials on the loudness discomfort level (LDL); (2) assess the intrasession stability among three LDL trials; and (3) examine the relationships between the speech LDL and the pure-tone and spondee thresholds. Ninety-six adults with mild-to-moderate sensorineural hearing loss were tested. Findings showed little or no difference among five commercially available speech materials. Thus, it was concluded that differences in speech materials do not comprise a major source of variability among studies when comparing mean LDL data. Group means may, however, obscure significant individual variations in LDL's that result from differing speech materials. Considerable LDL variability among listeners with similar thresholds was found, suggesting an intolerably high error rate for predictive purposes.
