2.2.3 Equalization of active speaker (REM)
During the speaker equalization procedure, the headset with the REM
probes must be placed in front of the speaker, at the same distance and in
the same position as will be occupied by the patient's head when the test is
actually conducted. For best results, it is advisable to fit the headset directly
to the patient before running the equalization procedure. The distance of 1
m from the speaker is the optimum distance both for equalization purposes
and for conducting the REM test. Make certain that there are no
obstructions (e.g. hair) covering the microphones.
For more details, refer to the manual entitled Maestro – Fitting and hearing
aid test functionalities – User Manual.
