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 completely masked. This is the
minimum masking level (MML).
• Set the volume 5–10 dB above the threshold level. (Volume
can be set above 10 dB if necessary but should not exceed
the MML).
Set the TSG bandwidth
• Our TSG defaults to a broadband white noise setting. There
are 4 sound preset options to choose from.Each option’s
frequency range can be customized to patient preference
using the Range option. (Figure 4)
3. 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 ‘Ear to Ear Synchronization’ 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. Off is the default
setting in TSG. (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, allowing manual
volume adjustments to override the Environmental Steering
in any environment.
