| Resumo: | Aim: To verify the accuracy of the diotic and antiphasic digits-in-noise (DIN) test in
Brazilian Portuguese in four criteria for analyzing the gold standard test and the
influence of demographic and socioeconomic variables. Methodology: Two studies
were designed:Study 1 Hearing Accuracy applying DIN with diotic and antiphasic
stimuli, via 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 DIN 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 DIN 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 DIN. There was a positive correlation between diotic
and antiphasic DIN and degree of hearing loss. In study 2, 151 normal hearing subjects
demonstrated worse answers with older age, less education and socioeconomic level
on the DIN, 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, education and socioeconomic level influence the response to diotic DIN. |
