Interventions
- cochlear implant user performance prediction — DIAGNOSTIC_TESTA battery of visual cognitive tests will be combined to identify a set of tests that can predict user performance in speech-in-noise and music perception.
Study Details
Despite improved technology, many cochlear implant (CI) recipients still struggle to understand speech in noise (SIN). Because the bottom-up acoustic signal generated by the implant is distorted relative to normal-hearing acoustic input, CI users rely more on top-down processing to decipher masked speech. To better predict outcomes for CI recipients, top-down auditory processing ability should be assessed. However, hearing impairment makes testing top-down auditory processing ability through auditory means difficult. The study aims to determine whether testing visual top-down processing can predict auditory top-down processing capability.
