For hearing aids where ear-to-ear synchronisation is enabled, your hearing care professional can also enable
environmental monitoring synchronisation so that the TBP 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 TBP 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 TBP 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 TBP module can also be set to mask the tinnitus sound, so to provide temporary
relief by introducing a more pleasant and controllable sound source.
TBP 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. The tinnitus sound generator volume can only be adjusted within the range set
by the hearing care professional.
The volume control is an optional feature in the TBP module used for adjusting the sound generator output level.
