摘要：A method of measuring electrically evoked auditory brainstem responses of a patient or animal body is provided. The method includes surgically implanting an auditory prosthesis having an electrode array, the electrode array positioned either intracochlear or substantially proximate a brainstem of the body. At least one electrode is stimulated in the electrode array. Electrically evoked auditory brainstem responses resulting from said stimulation are recorded using, at least in part, an electrode in the electrode array as a negative electrode, and a positive electrode positioned substantially proximate the vertex of the head of the body.

主权项：1. A method of fitting an auditory prosthesis using electrically evoked auditory brainstem responses of a patient or animal body, the prosthesis including an electrode array, the electrode array divided into a plurality of predefined groups, the method comprising: for each predefined group of electrodes, simultaneously stimulating the group of electrodes at a stimulation level;increasing the stimulation level until a measured evoked auditory brainstem response is observed;decreasing the stimulation level to determine the Threshold Reference (TR) stimulation level at which the measured evoked auditory brainstem response disappears; anddetermining, based at least in part on Threshold Reference (TR), at least one parameter selected from the group consisting of mean Most Comfortable Level (MCL) and a mean Threshold (T) for the group of electrodes; and determining at least one parameter selected from the group consisting of Most Comfortable Level (MCL) and Threshold (T) for at least one electrode in the electrode array.
