Currently, the most used technique for fitting cochlear implants involves setting the maximum stimulation levels
for each cochlear electrode, ignoring the thresholds. Even more, some clinical engineers are recommending
setting thresholds levels to null, to be sure an artificial tinnitus is not induced, as a result that free field
audiograms are usually not taken. After gathering experience with more than 300 fitted patients, all MED-EL
users, results show that this practice may be greatly ameliorated if correct free field audiograms are used for
setting the thresholds. Also, performing many fittings over a short period of time, with high maximum values have
adverse effects, “blurring” the understandability of speech, in an irreversible manner.
The presentation shows a better method for fitting, valid for everyone, but focused on children and toddlers,
because of the minimal feedback from them. The rationale for the method is also explained with concrete
examples.
