Preferential and non-preferential transmission of formant information by an analogue cochlear implant using noise: the role of the nerve threshold.

abstract：:The primary goal of most cochlear implant procedures is to improve a patient's ability to discriminate speech. To accomplish this, cochlear implants are programmed so as to maximize speech understanding. However, programming a cochlear implant can be an iterative, labor-intensive process that takes place over months. ...
