Models of speech perception by users of auditory neural prostheses - Project 1

Brief description of study

The purpose of this study is to understand the ways in which users of cochlear implants and auditory brain stem implants understand speech. This study is looking to enroll postlingually deaf Cochlear Implant (CI) users with hearing loss who have at least one year of experience with their device. There will be two groups of ten subjects each, defined by their use of processing strategies spectral-peak (SPEAK) or continuous-interleaved- sampling (CIS). Each experiment will be performed once for each subject. Psychological experiments will require at least two 3-hour sessions, the speech perception experiments two additional 3-hour session, and the non-invasive physiological measurements two 3-hoursessions, all of which will be conducted within a one year interval.
