The scientific concepts that form the basis for the device

The TSG Module provides sound enrichment with the aim of surrounding the tinnitus sound with a neutral
sound which is easily ignored. Sound enrichment is an important component of most approaches to tin-
nitus management, such as Tinnitus Retraining Therapy (TRT). To assist habituation to tinnitus, this needs
to be audible. The ideal level of the TSG module, therefore, should be set so that it starts to blend with the
tinnitus, and so that you can hear both your tinnitus as well as the sound used.
In a majority of instances, the TSG module can also be set to mask the tinnitus sound, so to provide tem-
porary relief by introducing a more pleasant and controllable sound source.
