Overview

Review highlights diagnostic challenges for hidden hearing loss in audiometry, suggesting biomarkers like electrocochleography and therapies for improvement.

Key Points

  • Hidden hearing loss presents diagnostic challenges for speech comprehension in noise, affecting neural coding and presenting as tinnitus or hyperacusis.
  • Among the novel biomarkers for cochlear synaptopathy are reductions in neural coding metrics, like ABR wave I and electrocochleography outcomes.
  • Observational analysis gathered insights from animal and human research to assess the effectiveness of new therapies for HHL.
  • The findings suggest significant clinical implications for audiologists and indicate a need for standardized test batteries to accurately diagnose HHL.
