Exploring spectral and temporal resolution in the apex for speech processor optimization

Brief description of study

This study will psychophysically explore the temporal and spectral parameter space in the apex to gain an understanding of the potential capabilities and limitations of apical stimulation. Additionally, we will correlate performance on our psychophysical tasks with performance on a speech in noise task and musical pitch task to determine how temporal and spectral cues relate to clinical performance. A correlation between either temporal or spectral resolution in the apex and clinical performance could be used to both guide future refinements of speech processing strategies as well as clinically predict who would benefit from specific processing strategies. We are looking to enroll patients with a 1. MED-EL cochlear implant.
