Hearing sensitivity is most commonly still reported in terms of pure tone thresholds. Unfortunately, simple procedures for predicting Speech Recognition Thresholds from Pure Tone Thresholds are not currently available. To remedy this problem, pure tone thresholds were collected from 802 individuals over the range of 250 to 8000 Hz. Five subsets of pure tone thresholds which are commonly used to report hearing status were then considered. An average correlation of 0.878 was found between the various pure tone indexes and the speech recognition threshold. Using regressions between pure tone and the speech measure, a table was constructed that allows conversion of the various pure tone indexes to a predicted speech recognition threshold and involves only a very simple computation.
听力敏感度目前最常仍以纯音听阈来报告。不幸的是，目前尚无从纯音听阈预测言语识别阈的简单方法。为解决这一问题，收集了802名个体在250至8000赫兹范围内的纯音听阈。然后考虑了常用于报告听力状况的五个纯音听阈子集。发现各种纯音指标与言语识别阈之间的平均相关性为0.878。利用纯音与言语测量之间的回归关系，构建了一个表格，该表格可将各种纯音指标转换为预测的言语识别阈，且仅涉及非常简单的计算。
