Speech discrimination in noise for patients with cochlear implants

The aim of the study was to evaluate the speech discrimination ability of postlingually deaf adults implanted with the Combi 40 cochlear implant in noise and to compare the results with the speech discrimination ability of patients provided with hearing aids. The 12-month postoperative hearing performance of 12 consecutive patients was tested using a sentence discrimination test in quiet and noise. The results of the present study demonstrate that all patients obtained substantial benefit from their implants even in situations coupled with noise. The speech understanding of cochlea-implanted patients appears to be better than that of patients provided with hearing aids. Very high scores (mean, 40.2%) were achieved at a signal-noise ratio of 15 dB.     

The cochlear implant--evolution of hearing and language with an artificial inner ear

One of the most spectacular progresses in modern medicine is the possibility to replace a deaf ear, a sensory organ in total by an implantable electronic prosthesis, a so-called cochlear implant (CI). The CI stimulates the auditory nerve by electrical pulses and thus generates the sensation of hearing along the auditory pathway. One of the most impressive aspects of cochlear implantation is the fact that small children with profound deafness who were able a few years ago to learn spoken language only to very limited extent may achieve nowadays an almost normal language development. Duration and intensity of the training of listening and spoken language vary considerably as a function of etiology and time of deafness. Most important for the development of language is sufficient stimulation of the auditory pathway during early childhood. Early diagnosis of a severe to profound deafness is most important in order to fit hearing aids or a cochlear implant without a time delay. Affected children need intensive training by professionals specialized in education and speech therapy. Adults and adolescents who lost their hearing when language acquisition was established may understand spoken language only a few weeks after receiving a cochlear implant. Several individuals are able to use the telephone. Preliminary results after bilateral cochlear implantation of children and adults show advantages. Not only do these subjects report "better hearing with two CI as compared to hearing with one CI," but some of them developed directional hearing in a rather short time lag after fitting the second implant. And in addition they achieve better speech discrimination in environmental noise.     

The influence of cochlear implantation on vowel articulation

PURPOSE: Speech of deaf persons differs considerably from that of speakers with normal hearing. The purpose of this study was to investigate the acoustic changes in articulation of corner vowels in deaf children and adults after cochlear implantation. METHODS: Thirteen prelingually deaf children and 12 postlingually deaf adults were included in the study. Voice samples of the isolated corner vowels /a/, /i/ and /u/ were analyzed before and 6-12 months after the implantation. The frequencies of the first (F1) and second (F2) formants, the F1/F2 ratio of all three corner vowels, and the area of the vowel triangle were calculated and compared before and 6-12 months after the implantation. RESULT: In the adults, no significant differences were detected in the formant frequencies, the F1/F2 ratio or the area of the vowel triangle. However, significant change in formant frequencies was detected in the group of 13 prelingually deaf children. After the implantation the F1 of /u/ decreased significantly, and favorable decreases of the F1 of /i/ and the F1/F2 ratio in /i/ and /u/ were close to being statistically significant. All changes caused better phonological difference between the two vowels. The significant change in the F1 of /u/ and the change of F1 of /i/ resulted in the expansion of the vowel space, which was expressed as an increase in the area of the vowel triangle. CONCLUSIONS: We suggest that in children the acquired hearing ability and further development of neuromuscular control of articulation are the reasons for the significant improvement after cochlear implantation. The results also suggest that the area of the vowel triangle is a useful and sensitive indicator of the more precise articulation after implantation. In order to achieve better and faster improvement of articulation, regular speech therapy should be included in the rehabilitation of deaf persons after cochlear implantation.
