METHOD OF ACTIVE TINNITUS SUPPRESSION Russian patent published in 2020 - IPC A61F11/00 A61N1/36 

FIELD: medicine.

SUBSTANCE: invention refers to methods of treating tinnitus. Sound exposure is combined with translingual neurostimulation. Treatment involves two stages. At the first stage, audibility thresholds of the patient are determined, and a frequency region of ear noise generation is evaluated. At the second stage, ear noise is suppressed by sound exposure combined with translingual neurostimulation. At the second stage, signals are presented through a device for personal listening to sound in the area of ear auricle generation based on data obtained at the first stage. For this purpose noise is used with bandwidth of 1 or 2 kHz, central noise frequency within range of 0.5 to 15 kHz. Patient notifies whether he hears his own ear noise against the background of the audio signal or not, by means of signals supplied from the panel in his hand. In a special case, at the first stage, tones and white noise are presented through the device for personal listening of sound with monaural or binaural signal intensity from 0 to 140 dB. In a particular case sound tones from 0.1 kHz to 16 kHz are presented, white noise is band-pass with width of 1 and 2 kHz, central frequency of noise varies from 0.5 to 15 kHz, duration of signals is 500 msec, period of presentation is 1 s. In a particular case, the patient either independently chooses the sound that is maximally similar in sound and volume with its own ear noise, or such selection is carried out according to the patient's reactions or instructions. In the special case at the second stage signals are white noise with duration of 5 sec. In the particular case, the noise is separated by pause of 5 s. In a particular case, translingual neurostimulation is carried out with a pulse frequency of 50–200 Hz with length of 20–35 min using a non-invasive neurostimulator.

EFFECT: method enables treating any type of tinnitus by using noise with central frequencies of 0_5 to 15 kHz and width of 1 and 2 kHz, and reducing the length of treatment.
