Could a mild electric zap to the brain silence ringing ears?
NCT ID NCT06628414
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a safe, low-dose electrical brain stimulation technique called tDCS to see if it can reduce the loudness and distress of tinnitus (ringing in the ears). Forty adults with tinnitus will receive multiple sessions, and researchers will measure changes in symptoms and brain activity. The goal is to gather the information needed to design a larger, more definitive clinical trial.
