The purpose of this study was to investigate how accurately pure-tone (250-6000 Hz) loudness discomfort levels (LDLs) predict speech (CID Test W-22) LDLs. One ear was tested in each of 50 elderly subjects with mild-to-moderate sensorineural hearing loss. The results revealed poor-to-fair correlations (r = 0.00 to 0.42) and large standard errors of estimate (approximately 9.5 dB). Thus, it was concluded that pure-tone LDLs are not accurate predictors of the speech LDL, and, if the clinician wants to ascertain the upper intensity for listening to speech, this measurement must be made directly.
本研究的目的是调查纯音（250 - 6000赫兹）响度不适阈（LDLs）对言语（CID测试W - 22）响度不适阈的预测准确性。对50名患有轻至中度感音神经性听力损失的老年受试者的单耳进行了测试。结果显示相关性较差至中等（r = 0.00至0.42）且估计标准误差较大（约9.5分贝）。因此，得出的结论是纯音响度不适阈不是言语响度不适阈的准确预测指标，并且，如果临床医生想要确定聆听言语的上限强度，必须直接进行此测量。
