Beltone Hearing Intruments – with Tinnitus Sound Generator (TSG)
Description of the device
The Tinnitus Sound Generator (TSG) Module is a software tool that generates sounds to be used in tinnitus
management programmes to relieve suffering from tinnitus.
Explanation of how the device functions
The TSG module is a frequency and amplitude shaped white-noise generator. Noise signal level and fre-
quency characteristics can be adjusted to the specifi c therapeutic needs as determined by your doctor,
audiologist or hearing healthcare professional.
Your doctor, audiologist or hearing healthcare professional can modulate the generated noise with the
purpose of making it more pleasant. The noise can then resemble, for example, crashing waves on a shore.
Modulation level and speed can also be confi gured to your likes and needs. An additional feature can be
enabled by your hearing healthcare professional that allows you to select predefi ned 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 synchronization this functionality can be ena-
bled by your hearing healthcare professional. This will cause the Tinnitus Sound Generator to synchronize
the sound in both hearing aids.
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. For hearing aids where ear to ear

synchronization is enabled your hearing healthcare professional can also enable environmental monitoring
synchronization so that the TSG noise level is automatically adjusted simultaneously 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.
The scientifi c 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.
