Objectives: This study aimed to assess if a short tinnitus treatment, combining counseling with broadband noise filtered by the hearing loss curves, provided significant relief in tinnitus patients.
Materials and methods: 25 tinnitus subjects of heterogeneous etiology were subjected to sound therapy, 1 hour per day, for 4 months. All of them underwent a unique initial counseling session aimed at undoing previous negative perceptions of tinnitus and highlighting the real expectations from tinnitus therapies. Customized stereo sound stimuli were designed by filtering broadband noise using the hearing loss curves of each ear. A monthly follow-up was carried out by assessing the severity of tinnitus through a validated Spanish version of the Tinnitus Handicap Inventory (THI).
Results: 88% (22 of 25) of the patients completing the treatment obtained significant relief after 4 months. After 4 months of treatment, the average decrease in THI from its initial value for the 22 successful participants was 29.
Conclusion: The average THI score reduction after 4 months of treatment can be considered to be an excellent improvement when compared with other similar studies. The proposed customized sound therapy was effective in reducing tinnitus in patients of heterogeneous etiology.
