9 Tinnitus Sound Generator module
Your Interton hearing aid includes the Tinnitus Sound Generator (TSG) module, a tool for generating
sounds to be used in tinnitus management programmes to relieve suffering from tinnitus.
The TSG can generate sounds adjusted to the specific therapeutic needs and your personal preference
as determined by your doctor, audiologist, or hearing care professional.
Depending on the selected hearing aid programme and the environment you are in, you will sometimes
hear the therapeutic sound resembling a continuous or fluctuating noise.
9.1 Indication for use of the TSG module
The Tinnitus Sound Generator Module is a tool to generate sounds to be used in a Tinnitus Management
Program to relieve patients suffering from Tinnitus. The target population is primarily the adult popula-
tion over 18 years of age. This product may also be used with children 5 years of age or older.
The Tinnitus Sound Generator module is targeted for healthcare professionals, which are treating
patients suffering from Tinnitus, as well as conventional hearing disorders. The fitting of the Tinnitus
Sound Generator module must be done by a hearing professional participating in a Tinnitus Manage-
ment Program.
9.2 User instructions for the TSG module
9.2.1 Description of device
The Tinnitus Sound Generator (TSG) Module is a software tool that generates sounds to be used in tin-
nitus management programmes to relieve suffering from tinnitus.
9.2.2 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 specific therapeutic needs as determined by your doctor,
audiologist or hearing care professional.
Your doctor, audiologist or hearing care professional can modulate the generated noise with the pur-
pose of making it more pleasant. The noise can then resemble, for example, breaking waves on a shore.
9.2.3 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 neu-
tral 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, so to provide
temporary relief by introducing a more pleasant and controllable sound source.
9.2.4 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.
