Introduction
Automatic REM automates the process of incorporating Real Ear Measurements
(REM) into the fitting process. The solution provides seamless, step by step
workflows that take advantage of the features of the Aurical FreeFit solution
for Automatic REM, and the Auditdata Primus, Interacoustics Affinity Suite and
Signia Unity fitting systems for Automatic REM 2, guiding the user through the
various steps of Real Ear Measurements and matching to targets from within the
Unitron TrueFitTM fitting software. This creates an easy and effective way of
incorporating Real Ear Measurement into the fitting process. The fitting
software will automatically identify the correct workflow based on the
measurement system installed. For additional details on programming and
fitting Unitron hearing instruments, please refer to the Unitron TrueFit user
guide.

Automatic REM workflow
Compatible with the Aurical FreeFit solution
Automatic REM can be accessed via the Fitting tab. It is accessible within
Unitron TrueFitTM fitting software when running Noah and connected to an
Aurical FreeFit system. If there are Automatic REM results from a previous
session, they will be visible regardless of connection status.
Note: If the Automatic REM is being run when the Automatic Adaptation Manager
is not yet at 100%, the percentage will be set to 100% for the duration of the
Automatic REM workflow. In addition, the app equalizer values will be set to
zero for the duration of the workflow. Both will be returned to their original
values on completion of the workflow.
Preparation probe tube calibration
Follow the on-screen instructions to calibrate the probe tubes. Click Close to
proceed.
The workflow can be run for either Left or Right or both ears. Click R / Start both / L to start Automatic REM.
Preparation configuration
While running Automatic REM for the first time, the only option is to select
Measure new real ear data. The software will guide you through the steps to
calibrate the probe tube, measure the REUG, Acoustic coupling, REOG, and MLE
(Microphone Location Effect).
REUG measurement
Follow the on-screen REUG preparation instructions then click R Start / L
Start to start the REUG measurement.
For a follow-up session with Automatic REM, you have the option to repeat
measurements for either or both ears. Select Reuse previous real ear data and
then one of the following two options:
· Reuse REUG measurements and run the workflow from the acoustic coupling and
REOG
· Reuse all measurements to re-run only the automatic match portion of the
workflow
Place the probe tip close to the eardrum and then press Start.
When the results of the REUG measurement are displayed, a green check mark
indicates that the measurements were completed successfully. If there were any
issues encountered with the measurements, a warning icon will be shown with a
brief status message. The user then has the option to repeat the measurement
if needed.

Real Ear Measurements: acoustic coupling, REOG, and MLE
Follow the preparation instructions:
Measure and match targets
Select the program that will be active during verification.
Set the maximum level at the eardrum at which to stop the measurement.
Note: Please make sure that the probe tube position doesn’t change while
inserting the hearing instrument(s).
Click Measure to perform the acoustic coupling, REOG, and MLE measurements.
Click Measure to automatically apply acoustic information (i.e. REUG, acoustic coupling, and REOG), run aided response measurements, adjust the hearing instrument output to match targets and obtain the hearing instrument responses.
In the summary of the results, a status indication in bold with a warning or an error symbol indicates an issue occurred during one or more of the measurements and a similar icon next to the specific measurement indicates if it was impacted. A green check mark indicates that the measurements completed successfully.
In the above scenario the REOG and MLE measurements completed successfully, but the acoustic coupling measurement was impacted by high ambient noise. Clicking on the Details button will provide additional details and recommendations.
In the above example, the green check marks indicate that all measurements completed successfully. If any one or more of the measurements encounter an issue, an appropriate warning/error icon and status message will be displayed. Select Details for each of the measurements to see an explanation of the results.

Finishing Automatic REM
Click Save to apply the changes to the fitting and store all measurements
within the current session in the Unitron TrueFit fitting software with the
option to add notes.
Once saved, you can view the results for the REUG, REOG, acoustic coupling and
aided measurements on the Fitting > Automatic REM screen.
Note: The REUG measurements are also displayed in the Client > REUG screen.

Automatic REM 2 workflow
Compatible with Auditdata Primus, Interacoustics Affinity Suite and Signia
Unity fitting systems
Automatic REM 2 can be accessed via the Fitting tab. It is accessible within
Unitron TrueFit fitting software when running Noah and connected to an
Auditdata Primus, Interacoustics Affinity Suite or Signia Unity fitting
system. If there are Automatic REM 2 results from a previous session, they
will be visible regardless of connection status.
Calibration
Follow the on-screen instructions to calibrate the probe tubes or select Skip
to move to the next step.
The workflow can be run for either Left or Right or both ears. Click R / Start both / L to start Automatic REM 2.
Check the calibration result and repeat if necessary. Measurements can be repeated bilaterally, or unilaterally as required.
Preparation
Choose the preferred fitting formula and select the REM system being used. If
launching the workflow within a training session, `Training Device’ will be
listed under REM system, as pictured below.
5
Unaided
This is the REUG measurement. Follow the on-screen preparation instructions
then click R / Start both / L to start the measurement or select Skip to move
to the next step.
Note: Please make sure that the probe tube position doesn’t change while
inserting the hearing instruments.
The ambient noise, acoustic coupling, REOG and MLE will all be measured during
this step, before automatically proceeding to match to target.
When the measurement is completed, results will be displayed for review. The
measurement can be repeated for any or all the input levels from this screen.
When the results of the REUG measurement are displayed, a green check mark indicates that the measurements were completed successfully. If there were any issues encountered with the measurements, a warning icon will be shown with a brief status message. The user then has the option to repeat the measurement if needed.
Confirm
The Automatic Adaptation Manager will be set to 100% upon completion of the
workflow. Should adjustments to the Automatic Adaptation Manager be required,
navigate to Fitting > Tuning.
Aided
Follow the on-screen preparation instructions. Select the input levels
required (65 dB is mandatory), then click Start to start the measurement.
6
Save
The final step presents a summary of the measurements, a reminder that the
gain level is set to 100%, and the option to leave a note on the session.
Click Save and Exit to complete the workflow.
Once saved, you can view the results for the REUG, REOG, Acoustic Coupling and
Aided Measurements on the Fitting > Automatic REM 2 screen.
Note: The REUG measurements are also displayed in the Client > REUG screen.

Glossary
Acoustic coupling – a measurement performed to characterise the acoustic
impact of the physical coupling of the hearing instrument to the client’s ear.
This is also known as the ear-to-coupler level difference (ECLD).
Aided Measurements – Real Ear Measurements (REM) performed with the hearing
instrument inserted in the clients ear and turned on.
Automatic REM and Automatic REM 2 – automated system for REM that provides
users with a seamless, step by step workflow that incorporates Real Ear
Measurements into the fitting process, directly in Unitron TrueFit fitting
software.
MLE – Microphone Location Effect
REOG – Real Ear Occluded Gain
REUG – Real Ear Unaided Gain
