A system for determining cochlear implant operating parameters for electrode contacts in an implantable electrode array. A first electrode contact is stimulated with an initial stimulation signal, and a channel fitting process is performed including: checking for a channel fitting response condition; if present then setting a channel operating parameter for the current electrode contact based on the channel fitting response condition, and ending the channel fitting process if parameters have been set for all electrode contacts. Otherwise, if the channel fitting response condition is not present or if channel operating parameters have not been set for all electrode contacts: selecting a next electrode contact, changing the stimulation level by a channel fitting increment, if a stimulation level limit has been reached, ending the channel fitting process, otherwise, stimulating the currently selected electrode contact with the stimulation signal at the current stimulation level and repeating the channel fitting process. |
