The First Fit Configurator
After entering the Vibrogram as a basis for the first fit,
the first fit configurator can be started.
This is done via selecting
”Fitting”
and then
”First
Fit…”
from the menu or using the highlighted icon in
figure 15.
First fit approach
First select whether the first fit should be done for
the left, the right or for both connected hearing
instruments, in the case of a bilateral fitting. In the
following example (figure 16) an Amadé is connected
on the right side. Therefore the other two options
cannot be selected here. Click on

Fitting formula and acclimatization level
A modified version of the
DSL I/O, NAL-NL2
or
NAL-
NL1,
as the
Fitting Formula
in the
Fitting Method
window, is recommended (figure 17). All three fitting
formulas are optimized to the output characteristics
of the VIBRANT SOUNDBRIDGE system. Setting the
Acclimatization Level reflects the client’s experience
with amplification from conventional hearing systems.
Level 1 should be selected for inexperienced hearing
aid users. Level 1 has the lowest starting volume and
cautious high frequency gain so sounds are not un-
comfortably loud. Level 2 is for “beginners” with some
amplification experience and level 3 for experienced
hearing aid users. Acclimatization level 4 can be used
as the setting for patients who are the most experi-
enced with amplification. Level 4 provides the highest
volume for all settings.
Next, the
Number of Programs
will be selected. Up
to 3 programs can be stored in the Amadé. One or
more programs can be created during the first fitting.
Additional (up to 3 total) programs can be added, at
any time, after the first fitting. There are 3 default pro-
grams: “Universal”, “Noisy Environment”, “TV/Music”.
After selecting the number of programs, click
“Apply
First Fit”
. This will complete the first fit configuration,
target gains will be calculated and stored in the Amadé
audio processor.
The programming is now complete; place the audio
processor on the implant site.
