AzBio Speech Understanding Performance in Quiet and Noise in High Performing Cochlear Implant Users

Objective: To evaluate high-performing cochlear implant patients’ performance on AzBio sentence testing. Methods: Retrospective review of prospectively collected database at a tertiary care hospital. Unilateral cochlear implant patients with AzBio testing were included. The primary outcome of interest was AzBio performance scores in quiet and at +10 and +5 decibels signal to noise (dB S/N). Results: One hundred eighty five subjects met inclusion criteria with scores for AzBio in quiet, 114 at +10 dB S/N, and 66 at +5 dB S/N. Linear mixed effects models showed performance significantly correlated with time since activation in all conditions (8.4%/yr; p
