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… CONTINUE READING
