2.6 Background on Real-Ear Measurements using REM440
When performing real-ear measurements there a certain things you should keep in mind in order to obtain
the best possible result. Some of these will inevitably also influence the precision of the curve obtained.
This section will walk through some important tips and tricks to remember when doing real-ear
measurements using the REM440.
2.6.1 Required Items
• The Affinity
2.0
/Equinox
2.0
hardware (if using Equinox
2.0
, note that you need an external loud speaker).
• The REM440 software.
• An In-situ headset (including a reference microphone).
• A probe tube microphone.
Note: If performing the RECD a couple of further parts are needed (see section 0 for details).
1) The Affinity
2.0
has a built-in loudspeaker in the lid through which the selected stimulus is presented.
The lid is opened by pressing the grey button on the front of the instrument.
If using the Equinox
2.0
plug the external loud speaker into the hardware and place it on the table in
front of the client.
The client should be seated in ½ - 1 meters distance facing this loudspeaker as illustrated above.
This distance is a compromise between measurement precision and client comfort. The client shall
be in this test position during all real-ear measurements.
If using the Equinox
2.0
an external speaker is required to present stimulus.
2) The real-ear measurements are controlled through the REM440 software. Open the software module
as described in section 0 or 0.
