TL;DR: The audiologic performance of 54 postlingually deafened adults wearing cochlear implants was uniformly evaluated and the multichannel designs enabled participants to recognize more environmental sounds, provided more speech reading enhancement, and enabled most users to understand limited speech in the sound‐only condition, compared to the single‐channel implant group.

Abstract: The audiologic performance of 54 postlingually deafened adults wearing cochlear implants was uniformly evaluated. The participants had 9 months' or more experience with one of five different cochlear prostheses (Los Angeles Single Channel (N = 11), Vienna Single Channel (N = 4), Melbourne Multichannel (N = 18), Utah Multichannel (N = 19), San Francisco Multichannel (N = 2). The multichannel designs enabled participants to recognize more environmental sounds, provided more speech reading enhancement, and enabled most users to understand limited speech in the sound-only condition, compared to the single-channel implant group.

TL;DR: In this article, the authors developed a nonparametric two-step procedure that enables them to estimate group effects under a very general form of correlation across time, and proposed several methods to estimate the bandwidth and show their asymptotyc optimality.

Auditory prostheses research with multiple channel intracochlear stimulation in man.
TL;DR: Results of pitch-matching experiments with the unilaterally deaf volunteer were consistent with tonotopic maps of the cochlea, and experiments indicated that a pitch continuum may be achieved by combining place and periodicity pitch modulation.

Speech recognition for 40 patients receiving multichannel cochlear implants.
TL;DR: Patients who received the Nucleus multichannel cochlear implant demonstrated significant improvement over preoperative results with a hearing aid for both lipreading enhancement and speech recognition without lipreading.

Four years of experience with cochlear prostheses.
TL;DR: It is shown that it is possible to reestablish some understanding of open speech through the use of the cochlear prosthesis without additional lipreading and a program has been established which aims at achieving experience with this prosthesis in a larger number of deaf people.

Evaluation of four Cochlear Implant Designs
TL;DR: Multichannel cochlear implant systems that provide spectral information in addition to temporal and intensity cues are consistently allowing profoundly deafened postlingual adults to recognize some words without visual cues.
