Hearing Aid Transition (HAT)

What is the hearing aid transition (HAT) test?

We understand you have new patients who attend with their existing hearing aid and sound preferences, but you do not have their historic fitting sessions to be able to relay those benefits and continue that satisfaction.

The Hearing aid transition test has been created to help you to copy fine tuning preferences from hearing aids which you do not have previous sessions stored for. This can be especially useful in the following scenarios:

Upgrading a patient’s hearing aid to a newer one where you do not have historic sessions

Upgrading a patient’s hearing aid to another brand compared to their current hearing aid

Enter/Select an audiogram from Noah or from the AUD module. If no audiogram is entered or selected, no independent targets will be displayed.

Enter the REM module and choose a test protocol which contains the Hearing Aid Transition Test. When prompted choose settings for your independent target algorithm, i.e. NAL-NL1, NAL-NL2 or DSL v.5.0.

Connect probe tubes to the REM reference microphones.

Click on the Tube Calibration button and follow the instructions on the screen, this process ensures that the probe tube is made acoustically invisible – enabling an effective display of the actual gain achieved at the tympanic membrane by the hearing aid.
