Abstract: The application relates to a bilateral hearing assistance system comprising first and second hearing assistance devices a processing unit, which in a NORMAL mode of operation processes an input audio signal based on configurable processing parameters and provides a processed electric stimulation signal. The system further includes one or more stimulation units for—in a TEST mode delivers first and second electric TEST stimulation signals to output units of said first and second devices respectively. The application further relates to a method of fitting a bilateral hearing assistance system to a particular user. The disclosure provides a measure allowing an improved fitting of bilaterally implanted Cochlear Implant users. The system further includes an evaluation unit configured to analyze the recorded physiological response of the user and to provide an objective measure of the user's perception of said TEST stimulation signals.
