REOR/REOG measurements

REOR (Real-Ear Occluded Response): The REOR accounts f or the SPL across f requencies measured in
the ear canal with the hearing aid in place and turned of f .
REOG (Real-Ear Occluded Gain): The REOG accounts f or the gain across f requencies measured in the
ear canal with the hearing aid in place turned of f . This is obtained by subtracting the input signal f rom the
REOR.
The REOR/REOG is of ten used to assess the venting of a hearing aid and whether it is f unctioning as
expected. It may also help in revealing if the vent is introducing unwanted acoustic ef f ects.
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) Perf orm 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 f rom the speaker.
Ensure that the probe tubes are calibrated bef ore placing them in the ear canal (see section 0 about
tube calibration).
6) Caref ully insert the hearing aid without moving the probe tube. Ensure that the hearing aid is
switched off.
