Due to the way in which this feature has been implemented you will not need to recreate new protocols
to use this function. It uses the settings you already have in your existing protocols.
Please note: when running measurements of this type you will only be using one reference microphone
to monitor the signal from the speaker. This is the right microphone by default but it can be swapped to
the left microphone by using the ‘use opposite ref. mic. Button’.
It is also essential that the position of the patient in relation to the REM speaker is maintained at 0° as
this will ensure that the same signal intensity is reaching each ear as they are equal distance from the
speaker.
3. Connect probe tubes to the REM reference microphones.
4. Click on the Tube Calibration button
and follow the instructions on the screen, this process
ensures that the probe tube is made acoustically invisible – enabling an effective display of the actual
gain achieved at the tympanic membrane by the hearing aid.
On running the calibration you will notice that in Binaural mode there is an automated procedure to
calibrate both Left and Right REM tubes sequentially, without having to manually start each individually.
5. Position the patient approximately 0.5 metres from the REM loudspeaker.
6. Perform otoscopy to ensure the ear canal is clear.
7. Snap the REM headsets on the REM headband and place on patient’s ear.
8. Choose a relevant protocol to perform your verification, in this example the default ‘Adult Insertion Gain’
protocol has been used.
Note: For this example, an Insertion Gain method has been used to demonstrate the Binaural REM feature,
however the feature is also compatible with protocols which perform this measurement in an Aided
Response method.
