Abstract: Providing stimulation signals for an implanted auditory prosthesis including receiving first and second sound signals at first and second signal receiving devices, each of the first and second signals having a signal-to-noise ratio; determining a signal parameter related to said signal-to-noise ratio of each of the first and second signals; selecting one of the first and second signals which has the greater signal-to-noise ratio; and generating stimulation signals for the implanted auditory prosthesis based on said selected sound signal.

Abstract: System and methods for fitting a cochlear implant for a recipient. In a fitting method, receiving, at an acoustic domain user interface, an acoustic target intensity for each of a plurality of frequency channels at which the recipient is to experience a desired percept; loading into a speech processor unit of the cochlear implant a MAP specifying a stimulation signal current level corresponding to a selected acoustic target; presenting the selected acoustic target to the cochlear implant so as to cause the cochlear implant to deliver electrical stimulation to the recipient at the current level corresponding to the selected acoustic target; and upon receipt of an external command: adjusting the current level corresponding to the selected acoustic target; and repeating the loading and the presenting steps.
