Overview

Assessment shows CAEP test effectively estimates hearing thresholds in individuals with and without hearing loss.

Key Points

  • The CAEP test matches behavioral thresholds closely, achieving a maximum difference of ≤ 15 dB.
  • Participants with hearing loss exhibited a mean difference of ≤ 10 dB between CAEP and behavioral thresholds.
  • Behavioral hearing thresholds were measured across multiple frequencies (500 to 4000-Hz) using a clinical AEP system.
  • These findings support the use of CAEP for estimating hearing thresholds, indicating its clinical relevance.
