Frequency-Limiting Effects on Speech and Environmental Sound Identification for Cochlear Implant andNormal Hearing Listeners

摘要

Background and ObjectivesIt is important to understand the frequency region of cues used, and not used, by cochlear implant (CI) recipients. Speech and environmental sound recognition by individuals with CI and normal-hearing (NH) was measured. Gradients were also computed to evaluate the pattern of change in identification performance with respect to the low-pass filtering or high-pass filtering cutoff frequencies.
