Ease and Accuracy with the FP35 Touch Hearing Aid Analyzer! Move your hearing aid fittings into the world of the touch screen! The new FP35 Touch adds a new interactive dimension to hearing instrument verification. Touch the screen to navigate to the desired test screen or to make changes to important settings. Swipe the screen and move to the next one or call up local menus—real control at your fingertips! Real Ear Measures Real-ear measurements ensure that your hearing aid fittings are solid and based upon actual data not just predictions. Patients will really appreciate you going the extra mile for them to provide great customer service. And if the patient comes back, complaining that the hearing aid is no longer working like before, real-ear measurements can save you valuable time in troubleshooting the problem. Visible Speech Real-ear measurements can be performed conventionally using the newly improved Digital Speech signal or you can use Visible Speech with live or pre-recorded actual speech signals. Switch between using the built-in signals and the Visible Speech signals with a simple touch to the screen. Want to see the exact sound level values at the ear? Switch between the graphical and numerical displays with another simple touch of the stylus. Fitting Formulas The fitting formulas available on the FP35 Touch include DSL i/o, NAL-NL1, MOD NAL (for mild/ moderate gain open fit aids), and the usual linear fittings rules. Two simple swipes from any of the realear measurement screens will bring up the target menu and allow you to adjust the formula settings. Return to the measurement screen with a closing swipe.

To create coupler targets customized to the patient’s ear response, measure the real-ear to coupler difference (RECD). This allows you to simulate realear measurements while providing the convenience of sound chamber measurements. This technique was developed primarily for fitting hearing aids on children, but it can also be a time-saver in pre-fitting hearing aids for adult patients before they come into the office for their fitting. It is even more convenient and accurate if you use the FP35 Touch Audiometer Option to measure the patient’s threshold levels. The FONIX NOAH Real-ear Module...
