REIG Measurements

REIG (Real-Ear Insertion Gain): The REIG accounts for the gain across frequencies provided by the
hearing aid alone. This is obtained by subtracting the REUR from the REAR or the REUG from the REAG.
The REIG is most often used to verify if a given hearing aid setting is providing an acceptable level of gain
compared to the prescribed REIG target.

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 an otoscopic examination.
5) Mount the probe tube on the in-situ headset and place it on the client who should be seated ½-1
meters from the speaker.
Ensure that the probe tubes are calibrated before placing them in the ear canal (see section 0 about
tube calibration).
6) Measure the REUG/REUR (see section 0) or select a predicted REUG/REUR (see section 0).
Note: Since the REIG is a calculation the system will require that you perform the REUR before
performing the REIG.
