U.S. Pat. No. 8,579,796, which discloses a method of treatment of tinnitus wherein an acoustic signal to is provided to a subject, wherein said acoustic signal comprises a non-sinusoidal pulsating electric waveform having a pulse repetition rate less than 100 Hz, and wherein said pulsating electric waveform is selected from the group consisting of square waves, triangle waves, and sawtooth waves, said pulsating waveform further comprises a sequence of three of said waves each of a predetermined duration, and said sequence comprises a first square wave, followed by a triangular wave, followed by a second square wave.

J Neurosci. 2015 Jun. 3; 35(22):8579-92 “Inhibition shapes acoustic responsiveness in spherical bushy cells” Christian Keine et al. This publication particularly discloses repetitive stimulations (100 ms duration, 5 ms cos 2 ramps, 300 ms interstimulus interval, 200-300 repetitions) with stimulation loudness was 20-30 dB SPLs above the respective threshold.”

Cognitive neuroscience and neuropsychology. Vol 13 No 4 25 Mar. 2002. “Lateral inhibition in the auditory cortex: An EEG index of tinnitus?” Alexander Kadner et al., This publication discloses that tinnitus related activity changes the intensity dependence of the N100 in a frequency specific manner. The experimental data show statistically significant reductions in the intensity dependence of the N100 in response to 2000 Hz tones and a non-significant increase in the intensity dependence of responses to the tinnitus frequency tones (4000 Hz tones).”
