摘　　要：目的比较手动测试取值与软件自动描记取值所得普通话双音节词汇表言语识别阈(speech recognition threshold,SRT),并探讨其临床应用的意义。方法选取128例正常人(听力正常组)以及57例从事噪声作业的工人(噪声组)为受试对象,均以普通话作为日常交流方式。应用丹麦Madsen Conera临床诊断听力计,采用难度等价性一致的一组双音节词汇表作为测试材料,测试初始给声强度为PTA上20dB,将手动取值获得的言语识别阈与Conera听力计工作软件自动生成的言语识别阈进行对比分析。结果听力正常组语频听阈均值7.63±5.78dB HL,自动取值所得SRT为7.84±3.98dB HL,手动取值所得SRT为9.19±4.47dB HL;噪声组语频听阈均值27.18±19.13dB HL,自动取值所得SRT为16.10±8.40dB HL,手动取值所得的SRT为18.81±9.52dB HL。两组手动取值所得的SRT值高于自动取值所得的SRT值(P<0.01)。结论自动取值SRT与手动取值SRT有差异,听力正常人的言语识别阈可用自动取值方法测试,便于听力正常人群的筛查;对听力障碍人群的SRT检查,更适合应用手动测试取值方法。Objective To compare the results of manually-tested speech recognition threshold （SRT） with automatically software-recorded SRT in the trial of Mandarin disyllahie test, exploring the significance to the clini-cal applying. Methods 128 normal people of different ages without hearing loss and 57 workers exposed to noise in an automobile manufacturing was selected. These two group of volunteers speak mainly Mandarin in their daily life. MADSEN Conera （Danmark） clinical audiometr was applied. A group of double syllable word list with the same dif- ficulty of equivalence was used as test material. The initial presentation level was 20 dB HL higher than PTA. Then compared the results of manually-tested SRT with automatically software-recorded SRT. Results In the normal group, the automatic value SRT was 7.84±3.98 dB HI., the manual value was 9.19±4.47 dB HL,and the average value of speech frequency threshold was 7.63±5.78 dB HL. In the noise group, the automatic value SRT was 6.10 8.40 dB HL,the manual value was 18.81±9.52 dB HL, and the average value of language frequency threshold was 27.18±19.13 dB HI.. There was significant difference between the values of SRT tested manually and recorded automatically （P〈0.01）. ConcLusion There are differences between SRT valued manually and automatically. The SRT in people with normal hearing can he tested using automatic-recorded method. This method is convenient for screening in people without hearing loss. To exam in people with hearing loss, the manual test is more appropriate.
