    A multiple-channel cochlear implant: an evaluation using open-set CID sentences
    Clark, Graeme M. ; Tong, Yit Chow ; Martin, Lois F. A. ( 1981)
    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 been confirmed with open-set CID everyday sentence tests. Using the implant alone, the patients obtained 8% and 14% scores with pre-recorded 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 conjunction 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.

    A patient with a total hearing loss had a multiple-electrode cochlear implant performed on 1 August 1978 (Clark et. Al. 1979). Preliminary findings (Tong et al 1979) have shown that low and high pitch are discriminated on a place basis. Stimulating different electrodes produced the vowel colours.......
