Foundations of Cochlear Implants: Electrical Stimulation of the Ear

---

1.  The mode of stimulation that is most commonly used in modern Nucleus implants is: Bipolar Monopolar Unipolar Tripolar

2.  In a cochlear implant system, charge is equal to: Maxima x Rate per channel Current level The T & C levels Current level x Pulse width

3.  In the ACE coding strategy, maxima are: The frequency bins with the largest amplitudes that are selected for stimulation The full range of frequencies available for stimulation The maximum rates that are possible for an individual Not useful

4.  The clinician's main goal when creating a MAP (i.e., measuring T and C levels) should be to: Concentrate on C levels only Get a stable MAP that never has to change Establish and maintain a true and comfortable loudness percept for the recipient Ask the recipient if the MAP sounds good to them

5.  In regards to MAPping, the following are possible benefits of a perimodiolar electrode: Less channel interaction More focused stimulation Higher T and C levels Both A and B

6.  SCAN technology is used to: Ensure the best SmartSound options are chosen in each situation Give the recipient manual control over their hearing Improve recipient performance significantly Both A and C

7.  Master Volume is ideal to use in which of the following circumstances? A recipient who wants an automatic hearing experience A recipient with a stable MAP whose speech perception results are poorer than they expected A recipient who has a narrow dynamic range, can understand advanced features on their Remote Assistant and who is not coming back to the clinic for several weeks A recipient who does not understand how to use the volume or program controls on their Remote Assistant

8.  What can SmartSound iQ options provide to a recipient? Better hearing in noise Better hearing for quiet sounds An automatic hearing experience All of the above

9.  When used by a recipient, sensitivity adjusts: The input to the microphone The output of the electrodes The T levels for the recipient The number of maxima

10.  If a recipient wants more control over their hearing, clinicians may consider giving them: Volume Control Manual Programs Sensitivity Control All of the above
