Treatment Evaluation of Neuromodulation for Tinnitus - Stage A3

The sound stimulus of PS6 is comprised of sequences of tones and is spectrally modified according to the participant's hearing thresholds so that different components of the sound stimulus can be sufficiently heard by the participant irrespective of their hearing characteristics (audiological profile). The tongue stimulus of PS6 is delivered by an array of electrical signals via 32 transmucosal electrodes contacting the anterodorsal surface of the tongue. The sound and tongue stimulus parameters are presented with certain stimulus rates and timing relationships between modalities.
