The new SAMBA, with its key features Automatic/Ambient Sound, Intelligent Sound Adapter and Remote
Control, sees the beginning of a new era for VIBRANT MED-EL’s audio processors. The Vibrogram function, for
direct threshold measurement through the SAMBA, integrated within the SYMFIT . software, is now
available for all SAMBA variants and for both the VIBRANT SOUNDBRIDGE and BONEBRIDGE implant
systems. SAMBA‘s sleek and ergonomic design allows for easier handling, and gives users
the option of personalizing their SAMBA by choosing from the wide selection of
cover colours and designs.
The SAMBA Fitting Guide enables the professional to follow a
straightforward tting workow. It provides step-by-step instruc-
tions and describes how the new features of the SAMBA function.
Hardware and Software setup
For hardware and software requirements, please refer to the SYMFIT . user manual and the SAMBA
user manual.
Introduction
Explaining the SAMBA features and functions
Handling of the SAMBA audio processor is explained
straight forward in the SAMBA IFU. Handy videos
showing quick demonstrations of how to use the
SAMBA audio processor can be found by selecting the
demo tab within the Hearing Instruments section of
the CONNEXX software.

THE AIM OF THIS CHAPTER IS TO OFFER A SIMPLE, YET EFFICIENT WORKFLOW FOR THE INITIAL FITTING OF THE
SAMBA AUDIO PROCESSOR BASED ON THE VIBROGRAM FITTING METHOD. IT WILL GUIDE THROUGH THE PROCESS
OF CREATING A CLIENT WITHIN THE CLIENT LIST, PERFORMING THE VIBROGRAM AND FURTHER ON APPLYING THE
FIRST FIT PROCEDURE.
Starting the tting session – entering client data
After starting up the CONNEXX software the Client
List and Data window appears (Figure ). In the First
Fit session a new client will be created. The elds Last
Name, First Name and the Date of Birth must be lled
in, other entries are optional.
If the client already exists respective data can be loa-
ded via selecting the client from the name list.

Detecting the SAMBA audio processor
First it is neccessary to detect the hearing instrument
via the detect connected instruments button on the
toolbar (Figure ). It is not necessary to select the
audio processor variant at this point. The detection
function automatically recognizes which audio proces-
sor is connected. Select Follow-Up tting (go to Fine
Tuning) on the window which appears and select Ok.
You will be forwarded to the Fine Tuning tab.

CHAPTER
The Vibrogram
The Vibrogram is a pure tone audiogram measured by direct stimulation of the inner ear through the Vibrant
Soundbridge or the BONEBRIDGE implant system. This innovative approach shows the response of hearing
thresholds at each measured frequency by directly driving the inner ear with the implant. The obtained levels
result in a specic, individual dynamic range which allows you to create a more precise rst t to optimize the
hearing benet for each patient. This method is applicable for all users, independent from hearing loss, surgical
technique, and placement. It can be performed with all versions of the SAMBA audio processor as well as with the
Amadé audio processors.
Loading the Vibrogram settings
To obtain the Vibrogram thresholds, calibration set-
tings have to be temporarily loaded into the audio
processor. Therefore, in the CONNEXX main menu bar,
Fitting > Test Settings should be selected and the
corresponding Test settings window (Figure ) will
appear. Now select Vibrogram Settings to load the
calibrated test settings.
The audio processor is now placed over the implant
coil on the patient’s head.
DO NOT CLOSE THE TEST SETTINGS WINDOW UNTIL YOU
HAVE PERFORMED THE VIBROGRAM MEASUREMENT.

CHAPTER
Completing the Vibrogram measurement
When the measurement is nished, close the Test Set-
tings window and the following message will appear
(Figure ).
Always select Yes in order to reprogram the previous
settings, as the calibrated test settings should not be
left in the SAMBA. The Vibrogram thresholds obtained
can now be entered in the Audiogram tab.
Measuring the Vibrogram
Select the Vibrogram tab from the six tabs available.
The Vibrogram table will appear (Figure ).
THE SAMBA AUDIO PROCESSOR MICROPHONES WILL BE
AUTOMATICALLY DEACTIVATED DURING THE MEASURE-
MENT AND ARE REACTIVATED WHEN CLOSING THE TEST
SETTINGS WINDOW. PLEASE NOTE: DO NOT MUTE THE
MICROPHONES MANUALLY DURING THIS PROCEDURE.
The method of obtaining a Vibrogram is the same as
obtaining an audiogram. Please advise the patient
accordingly. It is recommended to start the measure-
ment at kHz and dB above the bone conduction
threshold, introducing the user to the stimulus. Select
the corresponding button within the matrix to activate
the tone and start the measurement. The tone will
remain active until either another test tone is activated
or the stop button is used.
Please note down the individual Vibrogram thresholds
obtained for the whole frequency range.
In case the dynamic range of the user is limited, it
might also be useful to obtain uncomfortable loudness
levels (UCL values) with the Vibrogram tab and then
transfer them into the CONNEXX audiogram using the
UCL symbols.

CHAPTER
Entering the Vibrogram thresholds in the
Audiogram Tab
Open the Audiogram tab which is the rst of ve
tabs in the CONNEXX software and insert the Vibro-
gram thresholds obtained. This data will be used by
CONNEXX to calculate the target gains for the audio
processor.
THE VIBROGRAM THRESHOLDS MUST BE ENTERED USING
THE AIR CONDUCTION (AC) SYMBOLS (SEE ARROW).
PLEASE EXTRAPOLATE THE VALUES AT Hz AND
Hz AS MARKED IN THE AUDIOGRAM (FIGURE ).
First Fit of the SAMBA audio processor
After entering the Vibrogram thresholds in the Audio-
gramm tab, select the symbol Detect connected inst-
ruments (Figure ).
The Detect hearing instruments
window will open (Figure ).
Select New tting (go to First Fit congurator) and
conrm your selection. You will be prompted in the
Save session window to store changes from the previ-
ous session. Press Ok to store the changes. The audio
processor will
be detected
and the Re-
mote control
conguration
window will
appear.
Figure
Select the Remote
Control tab and
activate the
VIBRANT MED-EL
remote control via
the checkbox and
select Ok (Figure
). The remote
control allows the user to switch between the different
tting programs as well as to change the overall volume
in each of these programs. If no remote control is selec-
ted only the Universal program is available in the SAMBA
audio processor.
AT THIS STAGE, IT IS ALSO POSSIBLE TO REGISTER THE
SIEMENS miniTekTM * AS AN ALTERNATIVE REMOTE CON-
TROL IF AVAILABLE. FOR A MORE DETAILED DESCRIPTI-
ON ON HOW TO USE THE miniTekTM, PLEASE REFER TO
THE CORRESPONDING APPENDIX.
