Personalized Music-Embedded Sound Therapy Based on Gating Modulation and Neural Decoupling Reduces Tinnitus Severity

This clinical trial evaluated a personalized music-embedded sound therapy for adults with chronic subjective tinnitus. Tinnitus is the perception of sound, such as ringing or buzzing, without an external source and can negatively affect quality of life. Participants were randomly assigned to one of two groups. One group received personalized music-embedded desynchronization sound therapy, using tones selected according to each participant's tinnitus frequency and embedded in music. The comparison group received low-frequency sound stimulation embedded in music. Both interventions were designed to be similar for participants. The main objective was to evaluate whether the personalized music-embedded sound therapy reduced tinnitus severity compared with low-frequency sound stimulation. Tinnitus severity was measured using the Tinnitus Handicap Inventory at baseline and during follow-up.
