Pitch-based electrode deactivation provides no speech benefit for ACE users

Evidence

Results indicated that there was no measurable benefit for deactivating channels based on pitch ranking for ACE users. Effects were negligible regardless of whether the deactivated channels were indiscriminable or discriminable based on pitch ranking. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2050
