REOR/REOG measurements

REOR (Real-Ear Occluded Response): The REOR accounts for the SPL across frequencies measured in
the ear canal with the hearing aid in place and turned off.
REOG (Real-Ear Occluded Gain): The REOG accounts for the gain across frequencies measured in the
ear canal with the hearing aid in place turned off. This is obtained by subtracting the input signal from the
REOR.
The REOR/REOG is often used to assess the venting of a hearing aid and whether it is functioning as
expected. It may also help in revealing if the vent is introducing unwanted acoustic effects.
The REOR/REOG is a good check of whether you are blocking your probe tube ahead of beginning your
aided measurements.

1) Open the REM440 module by selecting the REM tab.
2) If needed select a test protocol in the List of Protocols. If you do not select a protocol the system
will automatically select a standard protocol.
3) Explain the procedure to the client.
4) Perform otoscopic examination.
5) Mount the probe tube on the in-situ headset and place it on the client who should be seated in ½-1
meters distance from the speaker.
Ensure that the probe tubes are calibrated before placing them in the ear canal (see section 0 about
tube calibration).
6) Carefully insert the hearing aid without moving the probe tube. Ensure that the hearing aid is
switched off.
7) Click on the REOG/REOR button if it is not already marked automatically.
A right click on the REOG/REOR button allows you to enter the Settings menu or Change colour of
the curve.
