A multiple-channel cochlear implant: an evaluation using open-set CID sentences.
A multiple-channel cochlear implant and speech processor have been used in two postlingually deaf adult patients with a total hearing loss, to enable them to perceive varying degrees of running speech. The results have veen confirmed with open-set CID everyday sentence tests. Using the implant alone, the patients obtained 8% and 14% scores with prerecorded material, and 34% and 36% scores for "live" presentations. This was equivalent to the perception of 35% of connected discourse. When the implant was used in conjuction with lipreading, improvements of 188% and 386% were obtained over lipreading alone, and the scores were 68% and 98% which were equivalent to the perception of 60% and 95% of connected discourse.
