This study reports on the long-term benefit of ultra-high-frequency masking with the UltraQuiet device. A commercial product, UltraQuiet provides a new form of high-frequency bone conduction therapy. To assess its effectiveness in tinnitus treatment, we selected 15 patients with problematic tinnitus and randomly assigned them to three variations of the medical-audiological tinnitus patient protocol modified for the UltraQuiet study. We assessed tinnitus relief by questionnaires directed at weighing patient response to overall effectiveness, tinnitus loudness, tinnitus severity, and tinnitus annoyance. Additionally, we performed audiological measures (including pure-tone and speech audiometry, minimal masking levels, pitch and loudness matching, and residual inhibition). All patients showed some long-term gains, and most exhibited relief in at least one measurement parameter, providing support for the use of high-frequency vibration in the treatment of tinnitus.
