Tinnitus affects 10-15% of adults and is frequently associated with impaired quality of life, anxiety, and sleep disturbance. Conventional sound therapies based on continuous masking provide inconsistent and short-lived relief, and the neural mechanisms underlying residual inhibition (RI) remain unclear. This study aims to determine whether 40 Hz burst stimulation with high-frequency carriers can achieve longer-lasting RI than continuous sound, and to explore its underlying neural mechanisms using EEG.
