The FONIX FP35 Hearing Aid Analyzer is a valuable tool for any hearing aid clinician. Within its sleek, compact design is the ability to check that the hearing aid is functioning properly as well as verify the suitability of its amplification for a particular patient. It also has excellent computer compatibility and can be controlled using a simple Windows-based interface from within NOAH.
REM
When the Real-ear Option is ordered, the FP35 Hearing aid Analyzer comes with the Integrated Probe Microphone, a lightweight, adjustable probe microphone for performing real-ear measurements (REM). REM is recommended by all the leading audiologists and researchers in the world for use in verifying the suitability of the hearing aid fitting for the patient. Hearing aid fitting software can only give you the best guess of the hearing aid amplification inside the patient’s ear. The only way you can know for sure is to test it with REM.

The Real-ear Option comes with the non-linear fitting formulas of DSL, NAL-NL1, and the new MOD NAL for mild to moderate gain hearing aids. Test results are available in both the traditional insertion gain format and the newer Real-ear SPL test screen that allows you to compare REM results with the patient’s HTLs and UCLs. All measurements are automatically converted between insertion gain and SPL, so you never have to duplicate curves to look at them from a different perspective.
