[Mass data and psychoacoustic interpretations of patients with 8-channel cochlear implants (author's transl)]

Six patients are described following insertion of an 8-channel cochlear implant. The prosthesis was modified from the Vocoder technique, and was implanted by a simplified method of the procedure previously reported by us. In addition to the perception of background noise as well as the differentiation of periodicity and frequencies, a distinct improvement of the patients' speech discriminations could be observed with this technique.
