Introduction: The early identification of hearing loss in students is essential to ensure appropriate educational and social development. Objective: This study aims to evaluate the agreement between different hearing test procedures and the digits-in-noise test (DIN) among students. Method: This is a cross-sectional, observational, and prospective study conducted with 88 students from the Federal Institute of Education, Science, and Technology of Rio Grande do Norte (IFRN) - Parnamirim Campus, of whom 52.2% were female, with ages ranging from 15 to 45 years (mean age of 19.79 years). The results of tonal audiometry and otoacoustic emissions screenings (both transient-evoked and distortion product) were compared with the DIN test using the Mann-Whitney and Spearman correlation tests. Results: The findings indicated that most participants showed normal results across all tests, with high pass rates. In the Diotic DIN, 98.36% of the students did not present hearing loss, while in the Antiphasic DIN, 99% did not present hearing loss. Regarding the Spearman correlation, specifically, both Antiphase TDR and Diotic TDR show a positive correlation with ATL (r = 0.1454), but without statistical significance (p = 0.1766). For the other variables, EOAT (both OD and OE) and EOAPD (both ED and OE), the correlations are close to zero, ranging between -0.0115 and -0.0319 for Antiphase TDR and between -0.0115 and -0.0319 for Diotic TDR. The p-values also indicate a lack of statistical significance for all these correlations, with p ranging between 0.7693 and 0.9154.
