Key Findings
  • People without tinnitus reacted only to unpleasant sounds, showing a normal stress response.
  • People with severe tinnitus or hyperacusis showed heightened stress response where they even treated harmless sounds as threads.


Other Highlights
  • Tinnitus currently has no objective test-doctors rely on patient self-reports to gauge severity.
  • Harvard-affiliated researchers tested 100 adults, half with tinnitus or hyperacusis, using sound exposure, facial video, and pupil tracking.
  • These biometric patterns accurately predicted tinnitus severity reported by participants.
  • The approach could lead to the first objective way to measure tinnitus, improving diagnosis and treatment tracking.
  • The method is noninvasive and low-cost, using video and eye-tracking instead of expensive medical equipment.
  • Researchers plan to build an open-access platform so others can use the tool in clinics and studies.
  • Results are preliminary and need validation in more diverse populations.
  • Current relief options remain: CBT, sound therapy, mindfulness, stress reduction, and medical evaluation.
