Affinity Additional Information
If you have calibrated for open fit only the signals used for this calibration are available in the
stimulus selection dropdown (see section 0).
12) Select input level using the Input level slider
13) Click START and follow the instructions on screen.
14) Place the client in front of the loudspeaker as shown on the picture. Click OK and front microphone
curve will be recorded. New instructions will immediately appear.
15) Turn the client around and click OK. The directionality curve will then be finalised as shown above
Note: The continuous measurement button is disabled for Directionality. Measurement time must therefore
be set in the REM440 setup (see section 2.6.2.7).

Binaural REM Measurements

This is a feature which allows binaural measurement of real ear measurements simultaneously. This makes
it easier and quicker to perform this measurement.
This test involves the placement of the probe tube microphone in each of the patient's ears at the same time
and referencing is performed with only one of the reference microphones. As a consequence this test
requires that the patient is orientated at 0° from the speaker to ensure that there is equal distance to the
speaker from each ear.
Binaural REM can only be used with stimuli which do not require active referencing during the measurement.
Therefore Binaural REM is not suitable for measurement with Warble Tone, Pink Noise, Random Noise,
Pure tone and Narrowband Noise.
No specific protocol is required to perform Binaural REM as it uses the settings from your existing protocols.
However a protocol can be defaulted to start up in Binaural REM measuring mode by enabling the below
setting in the REM protocol.

If using the Affinity with external speaker the client does not need to be turned around (see section 2.6.2.7 for directionality setup
options)
