The Scientific Concepts That Form The Basis For The Device; Technical Specifications - ReSound BE70 User Manual

in quiet environments, your doctor, audiologist or hearing healthcare 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 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.

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.
