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.

Available sounds
White noise signal which can be shaped with the following configurations:
The white noise signal can be modulated in amplitude with an attenuation depth of up to 14dB.
If your tinnitus troubles you only in quiet environments, your doctor, audiologist or hearing healthcare pro-
fessional can set the TSG Module so that it becomes audible exclusively in such surroundings. The overall
sound level can be adjusted via an optional volume control. Your doctor, audiologist or hearing healthcare
professional will review with you the need for having such a control.
TSG volume control
The sound generator is set to a specific loudness level by the hearing healthcare professional. When switch-
ing 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.

Caution
• The volume control is an optional feature in the TSG module used for adjusting the sound generator
output level. To prevent unintended usage by pediatric or physically or mentally challenged users, the
volume control must, if enabled, be configured to only provide a decrease of the sound generator output
level.

Tsg precautions
• Should the user develop any side effects from using the sound generator, such as dizziness, nausea,
headaches, perceived decrease in auditory function or increase in tinnitus perception, the user should
discontinue use of the sound generator and seek medical evaluation.
• Children and physically or mentally challenged users will require guardian supervision while wearing the
TSG hearing instrument.
