Modifying First Fit Based on Patient Psychoacoustics

---

1.  Which of these should be selected for patients with air conduction thresholds of 35 dB or better at 250 and 500 Hz? Open dome Double dome Closed dome Micro mold with 1.6 vent

2.  What indication would you have, upon First Fit, that the acoustical parameters selection might not be the most suitable based of the fitting formula selected, hearing loss and model selected? The hearing aids shut down to avoid feedback The patient reports hearing aids sound tinny The response curve in Connexx departs from target, especially in low frequencies There are no targets on screen

3.  What can be caused by the absence of measured Pure Tone UCL values? Connexx will estimate low UCL values and generate a conservative First Fit You will get the message that First Fit is not possible for lack of thresholds You won’t be able to run a Critical Gain on First Fit The hearing aids won’t have any gain

4.  What vent size is read by Connexx as an open fit when using custom hearing aids or earmolds? 1.3 mm 2 mm 3 mm None of the above

5.  The feature that allows to fit to target, modify the gain response to accommodate patient’s request and then have the hearing aids return to target over time is called: Automatic Equalizer Automatic Acclimatization First Fit Critical Gain

6.  A patient complains, upon First Fit, that everything sounds pretty good but voices are a little harsh. If counseling is unsuccessful, which of these response modifications would you use to accommodate the patients concern: Speech Power High Frequency Moderate

7.  A patient complains, upon First Fit, that everything sounds uncomfortably loud and that he/she doesn’t thing she can stand the hearing aids. If counseling is unsuccessful, which of these response modifications would you use to accommodate the patients concern: Speech Power High Frequency Moderate

8.  A patient complains, upon First Fit, that everything sounds too harsh or tinny. If counseling is unsuccessful, which of these response modifications would you use to accommodate the patients concern: Speech Power High Frequency Moderate

9.  Upon First Fit a patient states that he/she hears his/her own voice too much. The patient is using a RIC product, with a closed dome. The air conduction threshold at 250 Hz is 45 dB and 40 at 500 HZ. You decide to change the domes and do a new First Fit. Which of these would be your BEST choice? An open dome A semi open dome A double dome None of the above

10.  An experienced patient that has used CIC hearing aids for 5 years decides to give RIC hearing aids a try. This patient has a moderate flat hearing loss. Upon First Fit, the patient refers that sounds are not loud enough; they “don’t have power”. You first fitted the hearing aids using TwinCoreFit experienced with Closed domes. What would be the first change you should make? Change the Fitting algorithm to what the patient was using before, or as close as you can get it Change the dome for a custom ear mold Change the RIC hearing aids for CIC hearing aids None of the above
