1. A method of visualizing and controlling stimulation parameters for a hybrid hearing prosthesis having both electric and acoustic channels for delivery of electric and acoustic stimulation, respectively, the method comprising: displaying, at a display screen of a computing device, a graphical user interface (GUI) that includes a set of electric channel indicators indicative of threshold and comfort levels within each electric channel; and displaying, within the GUI at the display screen, a set of acoustic channel indicators indicative of threshold and comfort levels within each acoustic channel, wherein the set of electric channel indicators and the set of acoustic channel indicators are scaled and displayed so as to be visible simultaneously on the display screen within the GUI with visually comparable ranges, and wherein the GUI allows for the electric channel indicators and the acoustic channel indicators to be individually adjusted; detecting adjustment of at least one of the electric channel indicators or the acoustic channel indicators; and in response to the detected adjustment in of at least one of the electric channel indicators or the acoustic channel indicators, initiating an adjustment in a setting of the hybrid hearing prosthesis.
