14.2.3 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 neu-
tral sound, which is easily ignored. Sound enrichment is an important component of most approaches to
tinnitus 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.
14.2.4 TSG volume control
The sound generator is set to a specific loudness level by the hearing care professional. When switching
the sound generator on, the volume will have this optimal setting. Therefore, it might not be necessary to
control the volume (loudness) manually. However, the volume control provides the ability to adjust the
volume, or amount of stimulus, to the liking of the user.
The volume control is an optional feature in the TSG module used for adjusting the sound generator
output level.
14.2.5 Using TSG with smartphone apps
The tinnitus sound generator control via hearing aid push buttons can be enhanced with wireless control
from a TSG control app on a smartphone or mobile device. This functionality is available in supported
hearing aids when a hearing care professional has enabled the TSG functionality during fitting of the
hearing aid.

NOTE:
To use smartphone apps, the hearing aid must be connected with the smartphone or
mobile device.
