- Abstract
<bold>Objective: </bold>Our aim was to determine the effect of acute changes in cochlear place of stimulation on cochlear implant (CI) sound quality.<bold>Design: </bold>In Experiment 1, 5 single-sided deaf (SSD) listeners fitted with a long (28-mm) electrode array were tested. Basal shifts in place of stimulation were implemented by turning off the most apical electrodes and reassigning the filters to more basal electrodes. In Experiment 2, 2 SSD patients fitted with a shorter (16.5-mm) electrode array were tested. Both basal and apical shifts in place of stimulation were implemented. The apical shifts were accomplished by current steering and creating a virtual place of stimulation more apical that that of the most apical electrode.<bold>Results: </bold>Listeners matched basal shifts by shifting, in the normal-hearing ear, the overall spectrum up in frequency and/or increasing voice pitch (F0). Listeners matched apical shifts by shifting down the overall frequency spectrum in the normal-hearing ear.<bold>Conclusion: </bold>One factor determining CI voice quality is the location of stimulation along the cochlear partition.
