Abstract:
BACKGROUND AND OBJECTIVES: Automated DPOAE (Distortion product otoacoustic emission) was tested on workers exposed to a noisy environmnent to determine its feasibility as a screening test for noise-induced hearing loss. SUBJECTS AND METHOD: Sensitivity and specificity were analyzed for in both automated DPOAE and Pure tone audiometry conducted on 300 subjects working in a noisy environment. Of these subjects, a subgroup of 40 workers who were available for a follow-up study underwent the same experiment again a year later, and the results were compared with the first one. RESULTS: In terms of the frequency of automated DPOAE, it was noted that it showed 91% sensitivity with a 9% false negative rate. The pass rate according to the period of service indicated statistical significance, although the results of a 1 year follow-up experiment did not indicate statistical significance. CONCLUSION: The automated DPOAE seems feasible to use as a screening test when frequency and adjusted reference criteria are considered.
