Overview
The goal of the present study is to use computationally driven models of speech understanding in CI users to guide the search for which combination of active electrodes can yield the best speech understanding for a specific patient. It is hypothesized that model-recommended settings will result in significantly better speech understanding than standard-of-care settings.
Description
Aim 1 is to quantify speech understanding and sound quality with model-recommended combinations of active electrodes compared to standard settings, and compared to two control active electrode combinations. Aim 2 is to translate the model-driven recommendations from Aim 1 into practical guidance about how many (and possibly which) CI electrodes to deactivate.
