9.3 Using TSG with smart phone apps
The tinnitus sound generator control via hearing aid push buttons can be enhanced with wireless control
from a TSG control app on a smart phone or mobile device. This functionality is available in supported hear-
ing aids when a hearing care professional has enabled the TSG functionality during fitting of the hearing aid.
To use smart phone apps the hearing aid must be connected with the smart phone or mobile device.
9.4 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.

9.6 Prescription use of a Tinnitus Sound Generator (TSG) hearing aid
The TSG module should be used as prescribed by your doctor, audiologist or hearing care professional. In
order to avoid permanent hearing damages, the maximum daily usage depends on the level of the gener-
ated sound.
Should you develop any side effects from using the sound generator, such as dizziness, nausea, head-
aches, perceived decrease in auditory function or increase in tinnitus perception, you should discontinue
use of the sound generator and seek medical evaluation.
The target population is primarily the adult population over 18 years of age. This product may also be used
with children 5 years of age or older. However, children and physically or mentally challenged users will
require training by a doctor, audiologist, hearing care professional or the guardian for the insertion and
removal of the hearing aid containing the TSG module.
