Step by Step: The Audiologist’s Guide to Fitting the Inductive Earlens Contact Hearing Solution

---

1.  Choose the statement that describes Earlens placement and fitting process accurately: The Earlens device can be programmed at any stage of the fitting process. A trained physician places the lens on eardrum followed by fitting of the device by an audiologist. Lens placement is not necessary for programming of the Earlens device. Only one hearing professional is involved in placement and fitting of the Earlens devices.

2.  Signal processing features in the Earlens system include: Directional microphones Noise reduction Feedback measurement Directional microphone, noise reduction, and feedback measurement

3.  Earlens devices are recommended to be fit for patients who experience: Mild to moderately severe sensorineural hearing loss Mild to moderately severe mixed hearing loss Both sensorineural and mixed hearing losses. Mild to moderate conductive hearing loss

4.  Which of these statements is NOT true about calibration? Calibration is needed to determine the minimum signal level required to produce perception of sound Calibration can help to check the current status of the Earlens device Calibration can be used in-lieu of an audiogram Calibration should be performed at every visit

5.  New Earlens users may be unaccustomed to hearing high frequencies. This can be managed by: Adjusting low frequency gains per the comfort level of the patient Enabling auto-acclimatization for high frequencies only Enabling auto-acclimatization for the entire frequency range. Adjusting mid and high frequency gains per the comfort level of the patient.

6.  Choose the statement that lists the correct order of steps for programming the Earlens device. Audiogram entry, feedback measurement, fine-tuning Feedback measurement, fine-tuning, calibration Audiogram entry, fine-tuning, feedback measurement, calibration Audiogram entry, calibration, feedback measurement, fine-tuning

7.  The presence of oil and/or the Lens on the eardrum may result in: Own voice sounding tinny Own voice sounding too loud Own voice sounding muffled Others voice sounding too loud

8.  ELF Rx prescribes gains using: Hearing thresholds at a given frequency Calibration at a given frequency Loudness discomfort levels at a given frequency Both hearing thresholds and calibration at a given frequency

9.  The rationale for the Earlens fitting formula is: To maximize audibility Loudness equalization and normalization Comfort for loud sounds Loudness equalization only

10.  The fitting formula used to prescribe gains in ELF Rx is NAL-NL2 CAM2 DSL-version 5 Proprietary fitting formula developed by Earlens CORRECT
