FM Transparency

FM Transparency can be defined as "The condition in which equal inputs to the FM and hearing aid
microphones produce equal outputs from the hearing aid."
Clinical Practice Guidelines for Remote Microphone Hearing Assistance Technologies for Children and
Youth Birth to 21 Years. For more information, please refer to the AAA Guidelines.
The FM Transparency consists of 3 easy coupler measurements:
1. Hearing Aid alone
2. Hearing Aid + FM receiver attached, FM transmitter on/muted
3. Hearing Aid + FM receiver attached, transmitter microphone unmuted and positioned inside the test
chamber. NOTE: the hearing aid is still attached to the coupler/coupler mic, but it needs to be taken
out of the test chamber.
1. Launch the Affinity suite through Noah or OtoAccess™ and choose a patient
2. Launch the REM module
3. Select the FM Transparency protocol from the drop down menu
NOTE: FM Transparency assumes that the hearing aid has already been programmed to match the targets,
according to the patient's hearing loss and patient needs. Therefore, there is no need to show targets on the
screen. Targets and Fitting prescription information will not appear on the main screen when the FM
transparency is chosen.
The FM Transparency setup guide will pop up when the above protocol is chosen, instructing the patient on
how to setup for FM Transparency verification:
