Understanding how stress and arousal relate to tinnitus using eye and skin signals

Official title: Using sympathetic nervous system responses to evaluate distressing tinnitus: a pupillometry and skin conductance feasibility study.

Funded at James H Quillen VA Medical Center · NIH-11511699 · Data updated 2026-11-12

Researchers will test whether easy-to-measure signals like pupil size and skin conductance can reflect how distressing tinnitus feels in adults, especially Veterans.

Who could benefit from this research

Could help

Adults with tinnitus, particularly Veterans, who experience distress from their symptoms.

Less likely to help

People whose tinnitus is not distressing or who cannot participate in physiological testing may not benefit.

What this research studies

This project looks at whether objective bodily signals can reveal when tinnitus is bothering someone beyond what they report. It will measure pupil changes and skin conductance as participants with tinnitus perform listening tasks, to see if distressing tinnitus drives more mental effort and arousal. The study design is cross-sectional and will focus on adults, including Veterans, to explore the connection between tinnitus distress and physiological responses. Findings could help develop objective tools to better understand and track tinnitus impact in real life settings.

Why it matters

Potential benefit: If successful, patients could benefit from objective measures that complement personal reports, potentially guiding treatment choices and monitoring.

How similar studies have gone: Previous research has linked pupil dilation and skin conductance to listening effort and arousal, suggesting this approach could work for tinnitus distress.
