We wanted to assess the changes of speech perception ability and aided hearing thresholds as well as subjective satisfaction after upgrade to a new SP. Methods: Fifty-five patients who have used CI for 10 years or more and upgraded to a new SP were enrolled. Word recognition scores were assessed before the upgrade and compared to those assessed 1 year after the upgrade to the Nucleus 7 SP. Changes of aided hearing thresholds and C- and T-levels were analyzed. Results: Previous SPs were 3G in 5, Freedom in 40, N5 in 24, and N6 in 6. Speech perception remained relatively unaffected by SP upgrade. The C- and T-levels increased after SP upgrading and the aided thresholds with previous generation SPs were higher than those 1 year after SP upgrading at all frequencies. In questionnaires, subjects felt that there was a definite subjective benefit to upgrading while most (60%) felt no difference regarding the communication in noise. Conclusions: Speech perception remained similar, but there were improved hearing sensitivity and better satisfaction after SP upgrade.<\/jats:p>","DOI":"10.1177\/01455613241272467","type":"journal-article","created":{"date-parts":[[2024,11,9]],"date-time":"2024-11-09T03:57:21Z","timestamp":1731124641000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Speech
