SUMMARY:

Aim: To verify the accuracy of the diotic and antiphasic digits-in-noise (DRT) test in Brazilian Portuguese in four criteria for analyzing the golden pattern test and the influence of demographic and socioeconomic variables. Method: Two studies were designed: Accuracy Study 1 with normal-hearing and hearing impaired subjects applying TDR with diotic and antiphasic stimuli, by smartphone with in-ear headphones. ROC curves were established to define the cutoff point, measures of sensitivity, specificity, positive and negative predictive values for diotic and antiphasic TDR considering four criteria for analysis of pure tone audiometry (best and worst ear ≤ 25 and 40 dB). Study 2 was cross-sectional and prospective with normal hearing subjects. The diotic TDR was applied and the influences of sex, age, socioeconomic level, and education were analyzed. Results: In study 1 there were 102 subjects (18 to 90 years), 15.68% normal hearing, 69.60% with sensorineural hearing loss and 14.70% mixed. The highest sensitivity measure (96.51%) was found in the antiphasic stimulus for the worst ear mean criterion (≤ 25dB) with a cutoff of -11.90 dB in the TDR. There was a positive correlation between diotic and antiphasic TDR and degree of hearing loss. In study 2, 151 normal hearing subjects demonstrated the influence of age, education and socioeconomic level on the TDR, with no influence of gender. Conclusion: The sensitivity and specificity values in the diotic and antiphasic conditions were above 75% among the analyzed criteria. Age, schooling and socioeconomic level influence the response to diotic TDR.
