目的：分别应用言语清晰度测试词表 (材料一)和汉语测试词表 (材料二)对1组听力正常的受试者进行言语识别阈 (speech recognition threshold,SRT )测试，对所得结果进行相关分析，以期了解所选两种材料于听力正常人群的测试结果在临床上是否具有等价性，可否交互使用。方法：选取1组听力正常受试者 (50名，100耳)，先后通过两种材料下的言语识别阈测试，对所得结果进行比较。结果：受试者平均纯音听阈 (pure-tone average，PTA)为4.902 dB HL±3.12，言语清晰度测试词表与汉语测试词表所得 SRT值分别为6.90 dB HL±3.20和6.60 dB HL±3.63；两份材料所得SRT值与PTA的差值，分别为1.998 dB HL和1.698 dB HL。上述结果两两比较，P>0.05，差异均无统计学意义。结论：两种测试材料测听结果SRT与受试组PTA一致性好，两种材料所得SRT间比较显示测试结果具有可比性，在临床上可交互应用。

【Abstract】Objective：Applying Speech articulation test vocabulary test (material I)and Chinese glossary (material II)for 1 group of normal hearing subjects for speech recognition threshold (SRT)test,carrying out correlation analysis,to understand if the test results of two kinds of selected materials in normal hearing people in clinical is equivalent or could be used alternately.Methods：1 group of normal hearing subjects (50 people,100 ears)were selected,and the results were compared with the speech recognition threshold test of two kinds of materials.Results：The mean pure-tone average(PTA)of the group is 4.902 dB HL±3.12,and speech intelligibility test vocabulary and Chinese vocabulary test of the SRT values were 6.90dB HL ±3.20,and 6.6 dB HL ±3.63.The difference between the SRT value and the PTA value of the two materials was 1.9980 HL and 1.698 dB HL respectively.The results of the above comparison,had no significant difference(P>0.05).Conclusion：The results of the two tests were consistent with the PTA of the tested group,and the comparison between the SRT of the two materials showed that the test results were comparable and can be used in clinical practice.

语言是人类所特有的，用来表达意思，交流思想，传达信息的工具。在日常生活工作中，能否听懂言语是判断听功能状态的最重要的指标。检查受试者能否听懂言语，是对人类听功能评价的最重要的检查项目。因此，应用言语信号作为声刺激来检查受试者对言语的听阈和识别言语的能力是听力学检查中的基本方法之一，即言语测听法[1-2]。

言语测试始于20世纪初，测试时要求受试者重复所听见的单字、单词或者句子。在临……
