Substantial mismatch negatively influences speech recognition in postlingually deafened CI recipients, and acclimatization may be particularly challenging for older adults due to effects of aging on the auditory pathway. The present report investigated the influence of mismatch and age at implantation on speech recognition within the initial 6\u00a0months of CI use.<\/jats:p><\/jats:sec><jats:sec><jats:title>Study Design<\/jats:title><jats:p>Retrospective review.<\/jats:p><\/jats:sec><jats:sec><jats:title>Setting<\/jats:title><jats:p>Tertiary referral center.<\/jats:p><\/jats:sec><jats:sec><jats:title>Subjects and Methods<\/jats:title><jats:p>Forty\u2010eight postlingually deafened adult CI recipients of lateral wall electrode arrays underwent postoperative computed tomography to determine angular insertion depth of each electrode contact. Frequency\u2010to\u2010place mismatch was determined by comparing spiral ganglion place frequencies to default frequency filters. Consonant\u2010nucleus\u2010consonant (CNC) scores in the CI\u2010alone condition at 1, 3, and 6\u00a0months postactivation were compared to the degree of mismatch at 1500\u00a0Hz and age at implantation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Younger adult CI recipients experienced more rapid growth in speech recognition during the initial 6\u00a0months postactivation.
