The Tinnitus Sound Generator (TSG) is designed as a
sound therapy tool for tinnitus management. The TSG
features are the same in all technology levels, and can
be activated in any program.
Notes:
•
The TSG volume slider is in dBSPL.
•
The TSG settings overlayed on the audiogram can be
displayed in dBSPL or dBHL.
•
The binaural link option is not available for all features in
TSG. Only Amplitude Modulation, Modulation Speed and
Volume Control can be linked during the fitting.
•
For a TSG only program ensure the HI Microphone
option is turned ‘Off’.
1. Activate the TSG
• Select the program you want to activate the TSG in.
• Select the menu option in the upper right corner.
(Figure 1)
• Under the Fitting heading, select Tinnitus Sound
Generator. (Figure 1)
• Turn the Tinnitus Sound Generator slider to ‘On’.

2. Set the TSG volume
The volume of the TSG is set using the volume slider. The
volume should be set to a level that provides relief, but does
not completely mask the tinnitus. (Figure 3)
Note
: The volume slider is in dBSPL.
Below is a suggestion on how to first fit the TSG. It uses
the threshold of audibility as a starting point.
Find the TSG threshold of audibility (three steps)
• Using the volume slider, turn up the volume until the
patient reports that they can just barely hear the TSG
white noise. This is the TSG threshold of audibility.
• Increase the volume slider until the patient reports
they can no longer hear their tinnitus over the TSG
sound. This is the level at which their tinnitus is com-
pletely masked. This is the minimum masking level
(MML).
• Set the volume 5–10 dB above the threshold level.
(You can go higher than 10 dB if necessary, but do not
completely mask the tinnitus signal. This is where the
MML is important)
3. Set the TSG bandwidth
• Our TSG defaults to a broadband white noise setting.
There are 4 sound preset options to choose from. They
can be customized using the Range option to adjust the
frequency shaping. (Figure 4)
4. Customize the TSG features according to patient
preference
• Amplitude Modulation can be activated if the patient
finds it to be comfortable. (Figure 5)
• Amplitude Modulation causes the TSG to fluctuate in
volume, creating an “ocean-like” noise sequence. A Mild
setting offers less fluctuation, whereas a Strong setting
offers more fluctuation.
• Modulation Speed controls how quickly the volume
fluctuations occur. A Slow setting allows more time
between fluctuations, whereas a Fast setting allows
less time between fluctuations. (Figure 5)
• Selecting ‘Synchronize’ will enable ear-to-ear
commu nication, ensuring the features of the TSG are
automatically functioning symmetrically. (Figure 6)
5. Customize the Volume Control options
• The Volume Control options determine how the
volume of the TSG will be controlled. (Figure 7)
• Selecting ‘Volume Control’ will reassign the function
of the manual volume control to the TSG only for that
program.
• Selecting ‘Environmental Steering’ will allow the volume
of the sound generator to automatically adapt to the
listening environment, ensuring comfort in all situations.
• Selecting ‘Volume C Environmental Steering’
will combine the use of these two features. It allows
manual volume adjustments while the Environmental
Steering features is also active.
