%X <b>Objective: </b>To study the relationship between cortical auditory evoked potential (CAEP) thresholds and behavioral thresholds in pediatric populations with sensorineural hearing loss (SNHL). <b>Methods:</b> Fifteen children (mean age 6.8 years) with bilateral SNHL underwent behavioral pure-tone audiometry and CAEP testing at 0.5, 1, 2, and 4 kHz. CAEP thresholds were determined using tone bursts, and correlations between CAEP and pure-tone thresholds were analyzed using Pearson correlation and t-tests. <b>Results: </b>A strong positive correlation was observed between P1 thresholds and behavioral thresholds across all test frequencies: 0.5 kHz (r = 0.765, p &lt; 0.001), 1 kHz (r = 0.891, p &lt; 0.001), 2 kHz (r = 0.871, p &lt; 0.001), and 4 kHz (r = 0.922, p &lt; 0.001). Correction values between P1 and behavioral thresholds were established: 0.5 kHz (11 dB HL), 1 kHz (9 dB HL), 2 kHz (12 dB HL), and 4 kHz (13 dB HL). Mean P1 latencies ranged from 145.19 ms to 149.06 ms, and N1 latencies ranged from 212.34 ms to 232.26 ms across frequencies. <b>Conclusion: </b>The strong correlation between P1 and behavioral thresholds demonstrates the reliability of CAEP testing for estimating auditory thresholds in children. These findings support the use of CAEP testing as a reliable objective tool for threshold estimation, particularly in cases where behavioral responses cannot be reliably obtained. When adjusted with frequency-specific correction values, CAEP testing provides a reliable method for assessing hearing thresholds in pediatric populations.
