How to perform FM transparency verification

Step 1: Hearing aid alone (65 dB)

Note: FM transparency assumes that the hearing aid has already been programmed to match the target, according to the patient’s hearing loss.

Launch Affinity/Callisto Suite and select the REM module. Select the FM Transparency protocol from the drop-down menu (Figure 1).

Figure 1: FM Transparency protocol.

When the protocol has been selected, a setup guide will pop up with instructions on how to perform FM transparency verification (Figure 2). See below steps for further instructions.

1. Select the ‘HA Alone’ test.

2. Attach the hearing aid to the coupler/coupler microphone.

3. Position the hearing aid in the test chamber (Figure 3).
