Pitch-ranking-based electrode deactivation provides no measurable benefit for ACE implant users.

Evidence

Results indicated that there was no measurable benefit for deactivating channels based on pitch ranking for ACE users. … For an n-of-m strategy this number of deactivated electrodes may have been too small to demonstrate differences in performance; the selection of channels to deactivate was based purely on electrodes that were indiscriminable from one another in pitch ranking and for many users the number of indiscriminable electrode pairs was low so only small numbers were deactivated. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2111

• QUESTION: Would larger electrode deactivation counts, or selection based on other criteria, show benefits that this underpowered study missed?
