Abstract: By using a deconvolution technique, the outputs of a speech processor to the electrodes, based on current spread curves, the proper outputs of each eletrode are determined to provide the desired stimulation of the nerves. It has further been found that either overestimation or underestimation of the problem will result in improper stimulation and, in fact, a diminished accuracy of stimulation of the nerve rather than enhanced stimulation.Thus, the method relies on an inverse convolution of what amounts to the known desired stimulation of the auditory nerves to determine what information should be provided at the electrodes which are connected to the output channels of the stimulator system.
