【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(P0.01)。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。
[Abstract]:Objective to compare the speech recognition threshold and speech recognition threshold obtained from manual test and software automatic recording. Methods 128 normal subjects (normal hearing group) and 57 normal subjects (normal hearing group) were selected. Workers engaged in noise work (noise group) were subjects, Using Madsen Conera clinical diagnostic audiometer in Denmark, a group of dicyllabic vocabularies with identical difficulty equivalence were used as test materials. The initial acoustic intensity of the test was 20 dB on PTA. The speech recognition threshold obtained by manual measurement was compared with the speech recognition threshold generated automatically by Conera audiometer software. Results the average hearing threshold of normal hearing group was 7.63 卤5.78 dB HLand. The obtained SRT was 7.84 卤3.98 dB HLand the manual value of SRT was 9.19 卤4.47 dB HL.The average of hearing threshold of noise group was 27.18 卤19.13 dB HLL, the SRT of automatic value was 16.10 卤8.40 dB HLL, and the SRT of manual value was 18.81 卤9.52 dB HL.The SRT value of both groups was higher than that of SRT value. Conclusion there is a difference between automatic SRT and manual SRT. The speech recognition threshold of normal hearing people can be measured by automatic measurement method, which is convenient for the screening of normal hearing people. The SRT test of hearing impaired people is more suitable for manual testing.
