can be adjusted via a 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 synchronization is enabled your hearing care 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, since the hearing aid has a
volume control, 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 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 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, to provide temporary
relief by introducing a more pleasant and controllable sound source.
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
