Abstract

This study determined the accuracy of an AudioScope (AS) and pure-tone audiometer (PTA) screening at 40 dB HL from 500 to 4000 Hz in reference to a pure-tone threshold (PTT) test on 1210 ears of adult subjects 20 to 96 yr old. The overall results (averaged over age group and frequency) indicated that the AS and PTA screenings were equally accurate in reference to the PTT test. Averaged over the screening tests, the sensitivity was 91.4% with a false negative rate of 8.6% and the specificity was 93.5% with a false positive rate of 6.5%. As a function of age (averaged over frequency), the AS and PTA screenings had similar accuracy and decreased as age increased to about 60 yr old and then remained stable. As a function of frequency (averaged over age), each screening test had similar accuracy for each frequency. It was concluded that the results of a 40 dB HL AS or PTA screening are very accurate in reference to a PTT test.

摘要

本研究针对20至96岁成年受试者的1210只耳朵，以纯音阈值（PTT）测试为参照，测定了AudioScope（AS）和纯音听力计（PTA）在500至4000Hz、40dB HL下进行筛查的准确性。总体结果（按年龄组和频率平均）表明，与PTT测试相比，AS和PTA筛查的准确性相当。在筛查测试中，平均灵敏度为91.4%，假阴性率为8.6%；特异性为93.5%，假阳性率为6.5%。作为年龄的函数（按频率平均），AS和PTA筛查具有相似的准确性，随着年龄增长至约60岁时准确性下降，之后保持稳定。作为频率的函数（按年龄平均），每种筛查测试对每个频率的准确性相似。研究得出结论，与PTT测试相比，40dB HL的AS或PTA筛查结果非常准确。
