A Longitudinal Comparison of Environmental Sound Recognition in Adults With Hearing Aids Before and After Cochlear Implantation.

摘要: Purpose The aims of this study were (a) to longitudinally assess environmental sound recognition (ESR) before and after cochlear implantation in a sample postlingually deafened adults (b) the extent which spectro-temporal processing abilities influence ESR with implants (CIs). Method In longitudinal cohort study, 20 tested hearing aids on Familiar Environmental Sound Test-Identification AzBio sentences quiet pre-CI 6 months post-CI. A subset 11 participants also 12 Pre-CI was assessed using Spectral-temporally Modulated Ripple Test. Results Average accuracy (M = 63.60%) not significantly different from at 65.40%) or 69.09%) (55%), however, improved following by 10.91 percentage points, average. correlated moderately 12-month post-CI scores, trend toward significance for performance months. associated but speech Conclusions present findings failed demonstrate an overall significant improvement implantation. Nevertheless, more than half our showed some degree ESR.
