N-of-m strategies may resist improvement through electrode deactivation
Evidence
Some n-of-m (n channels with highest input amplitudes stimulated out of a possible m channels; e.g. ACE (8-of-22) or SPEAK) strategies may not benefit from deactivation of electrodes due to the simplification of the information delivery already inherent in the strategy. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2050 (

As speculated earlier it could be that the n-of-m strategies used in the Cochlear device may be less sensitive to channel overlap effects because not all channels are stimulated in each cycle. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2051 (

There is a wide range in performance for cochlear implant (CI) users and there is some evidence to suggest that implant fitting can be modified to improve performance if electrodes that do not provide distinct pitch information are de-activated. However, improvements in performance may not be the same for users of all CI devices; in particular for those with Cochlear devices using n-of-m strategies (ACE or SPEAK). — Dijk, Pim van, Physiology, Psychoacoustics and…, 2044 (
