Modulation level and speed can also be configured to your likes and needs. An additional feature can
be enabled by your hearing care professional that allows you to select predefined sounds that simulate
sounds from nature, such as breaking waves or running water.
If you have two wireless hearing aids that support ear-to-ear synchronisation this functionality can be
enabled by your hearing care professional. This will cause the Tinnitus Sound Generator to synchronise
the sound in both hearing aids.
If your tinnitus troubles you only in quiet environments, your doctor, audiologist or hearing care professional
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 care professional
will review with you the need for having such a control.
For hearing aids where ear to ear synchronisation is enabled your hearing care professional can also en-
able environmental monitoring synchronisation so that the TSG noise level is automatically adjusted simul-
taneously in both hearing aids dependent on the background sound level. Additionally if the hearing aid
has a volume control then the background noise level monitored by the hearing aid and the volume control
can be used simultaneously to adjust the generated noise level in both hearing aids.
9.2.3 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.
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.
