A system for analyzing operation of a cochlear stimulation system implanted in a patient, the system comprising: a sound generating system for generating a sound stimulus signal at a desired sound intensity level and frequency to detect operation of the cochlear stimulation system, an electrical cochlear response, ECR, detection system to determine if an ECR waveform is detected in a plurality of electrical signal responses received from the patient using surface electrodes, the electrical signal responses being generated in response to the sound stimulus signal having a desired low threshold sound level, and the ECR waveform being indicative of operation of the cochlear stimulation system; the ECR detection system being further configured to identify an intracochlear electrode associated with frequency of the sound stimulus signal that generated the response and to set a minimum current stimulation level for the identified intracochlear electrode to the current stimulation level used to generate the response; the ECR detection system being further configured to set a maximum current stimulation level for said intracochlear electrode by: calculating said maximum current stimulation level as: minimum current stimulation level + x% * minimum current stimulation level; or generating a sound stimulus signal at a desired maximum sound intensity and measuring said electrical signal responses generated in response to the sound stimulus signal, increasing the current stimulation level for the identified intracochlear electrode until the ECR waveform begins to show distortion, and setting the maximum current stimulation level for the identified intracochlear electrode to the current stimulation level where the ECR waveform begins to show distortion. a sound generating system for generating a sound stimulus signal at a desired sound intensity level and frequency to detect operation of the cochlear stimulation system, an electrical cochlear response, ECR, detection system to determine if an ECR waveform is detected in a plurality of electrical signal responses received from the patient using surface electrodes, the electrical signal responses being generated in response to the sound stimulus signal having a desired low threshold sound level, and the ECR waveform being indicative of operation of the cochlear stimulation system; the ECR detection system being further configured to identify an intracochlear electrode associated with frequency of the sound stimulus signal that generated the response and to set a minimum current stimulation level for the identified intracochlear electrode to the current stimulation level used to generate the response; the ECR detection system being further configured to set a maximum current stimulation level for said intracochlear electrode by: calculating said maximum current stimulation level as: minimum current stimulation level + x% * minimum current stimulation level; or generating a sound stimulus signal at a desired maximum sound intensity and measuring said electrical signal responses generated in response to the sound stimulus signal, increasing the current stimulation level for the identified intracochlear electrode until the ECR waveform begins to show distortion, and setting the maximum current stimulation level for the identified intracochlear electrode to the current stimulation level where the ECR waveform begins to show distortion. calculating said maximum current stimulation level as: minimum current stimulation level + x% * minimum current stimulation level; generating a sound stimulus signal at a desired maximum sound intensity and measuring said electrical signal responses generated in response to the sound stimulus signal, increasing the current stimulation level for the identified intracochlear electrode until the ECR waveform begins to show distortion, and setting the maximum current stimulation level for the identified intracochlear electrode to the current stimulation level where the ECR waveform begins to show distortion.
