Objective: The monosyllable speech perception ability after years of educational intervention was compared between prelingually deafened pediatric hearing aid users and their cochlear implant counterparts. Design: An open-set monosyllabic speech perception test was conducted on all subjects. The test required subjects to indicate a corresponding Japanese character to that spoken by the examiner. Fifty-two subjects with prelingual hearing impairment (47 hearing aid users and 5 cochlear implant users) were examined. Results: Hearing aid users with average pure-tone thresholds less than 90 dB HL demonstrated generally better monosyllable perception than 70%, which was equivalent or better performance than that of the cochlear implant group. Widely dispersed speech perception was observed within the 90–99 dB HL hearing-aid user group with most subjects demonstrating less than 50% speech perception. In the cluster of >100 dB HL, few cases demonstrated more than 50% in speech perception. The perception ability of the vowel part of each mora within the cochlear implant group was 100% and corresponding to that of hearing aid users with moderate and severe hearing loss. Conclusion: Hearing ability among cochlear implant users can be comparable with that of hearing aid users with average unaided pure-tone thresholds of 90 dB HL, after monosyllabic speech perception testing was performed.
Ive been doing my research on comparing CI vs. HA and I found this! I will keep looking for more articles that compare the two. But from what ive researched, CI today usually gives better hearing than what HAs can give for a profound loss. But CI appears to match the performance of HAs for a severe loss.
I also learned that those with severe losses generally score at least 70% speech on a difficult monosyllable test. I will do more research on speech scores for different degrees of hearing loss. But that article does show that those with profound losses generally scored below 50%. It's that group who with CI could hear comparable to those with severe losses and HAs. Speech would improve from perhaps 40% to perhaps 80% which is significent.
