Introduction: Early identification of hearing loss in students is essential to ensure adequate
educational and social development. Objective: To evaluate the agreement between hearing screening
procedures and the digits-in-noise test (DIN) in students. Method: This is a cross-sectional, observational,
and prospective study conducted with 83 students from the Federal Institute of Education, Science, and
Technology of Rio Grande do Norte (IFRN) – Parnamirim Campus (52.2% female; aged 15 and 45 years;
mean age: 19.79 years), who underwent audiometric screening, transient-evoked otoacoustic emissions
(TEOAE), distortion-product otoacoustic emissions (DPOAE), tympanometry, and the Digits-in-Noise test
(DIN) in both biotic and antiphasic modes. The DIN was administered via an online link on personal
smartphones with personal headphones, using an automatic adaptive procedure, with cutoff points of -6,7dB
SNR (diotic) and -11 dB SNR (antiphasic). A Frequency analysis of pass/fail outcomes was performed for
each procedure individually and in combination. Results: Among the participants, 38 (45,8%) passed all
procedures and none failed all tests. A total of 45 (54,2%) failed at least one test, with 21 (46,7%) failing
exclusively in TEOAE and 13 failing TEOAE combined with other tests. Only one student fails the biotic
DIN, also presenting failures in audiometry, tympanometry, and antiphasic DIN. Seven (8,4%) failed the
antiphasic DIN, of whom five (6,0%) also failed TEOAE; in one case (1,2%(, failure was isolated to the
antiphasic DIN, and in another (1,2%) there was failure in both DIN modes, associated with alterations in
audiometry and tympanometry. Conclusion: The DIN, particularly in the antiphasic mode, showed
agreement with the findings of conventional hearing screening, suggesting its applicability as a tool for
detecting hearing alterations in students.
