对兰州地区言语测听的几个常用数据进行了测算。供临床言语测听中参考。正常人言语接受阈(SRT):27.5±7.2dB;最大识别率(PBmax):正常听力(181耳)90.8±3.7％,传导性聋(85耳)87.0±5.6％,感音神经性聋(86耳)80.2±11.5％;校正值正常听力为17.5±5.5dB,传导性聋17.7±7.0dB,感音神经性聋18.6±8.9dB。感音神经性聋校正值受纯音听力图形的影响,陡降型听力校正值明显偏低。为提高测试的准确性,主张要求患者机械模仿,必须对每个测词应答。
Lanzhou area speech audiometry several commonly used data were measured. For clinical speech audiometry reference. Normal speech acceptance threshold (SRT): 27.5 ± 7.2dB; PBmax: 90.8 ± 3.7% for normal hearing (181 ears), 87.0 ± 5.6% for conductive hearing loss (85 ears), sensorineural hearing loss 86 ears) 80.2 ± 11.5%; the normal hearing value was 17.5 ± 5.5dB; the conductive hearing loss was 17.7 ± 7.0dB; the sensorineural hearing loss was 18.6 ± 8.9dB. The sensorineural deafness correction value is influenced by the pure tone audiogram, and the steep drop type hearing correction value is obviously lower. In order to improve the accuracy of the test, advocates requiring the patient to imitate the machine and must answer each test word.
