FONIX FP35 Hearing Aid Analyzer v6.12

fp35w_probe.psdFrye Electronics is pleased to announce the new version of the FONIX FP35 Hearing Aid Analyzer. Version 6.12 brings improvements to both the software and the hardware of this great portable analyzer. Most existing analyzers can easily be updated to the new software changes (hardware changes are also possible).

Improved Analysis

We have improved the frequency analysis of the Digital Speech signal used for testing advanced hearing aids. The new software takes into account the special needs of hearing aids with feedback suppression algorithms that has sometime interfered with the Digital Speech signal. The new analysis routines should provide the clinician with better test results without needing to disable the feedback controls of the hearing aid.

New Test for Frequency-Shifting Hearing Aids

Hearing aids that shift the frequency response of the input signal have enjoyed increasing popularity in recent times. We have added a new test to the FP35 analyzer that presents a single (or double) tone to the hearing aid and graphs the entire frequency response. This allows the user the verify that the hearing aid is correctly shifting the frequency response of the signal.

1/3rd Octave Analysis

We have added 1/3 Octave analysis to the Real-ear SPL and Coupler Multicurve test screens. This analyzes the hearing aid response with 1/3 Octave analysis instead of the 100 Hz-based FFT that Frye analyzers have always used. This change will make it easier to compare results with competing analyzers that use fractional octave analysis.

Battery Current Drain

The new FP35 hardware now allows for the measurement of battery current drain. This is a feature that has long been requested by our customers. (Battery pill purchase required.)

Updated NAL-NL1 Targets

We have implemented a modified version of the NAL-NL1 target more suitable for fitting low gain hearing aids such as Open Fit styles. These targets match the SPL targets found on some competing analyzers. The standard NAL-NL1 targets are also still available.
