Prefitting Evaluation of Cochlear Implant Patients

Arrangements are described for assessing potential fitting processes for a cochlear implant patient. A test stimulation sequence at a given test frequency is delivered to the cochlear implant patient. The test stimulation sequence includes jittered stimulation periods when the test frequency varies due to a jitter variation component, and unjittered stimulation periods when the test frequency is constant without a jitter variation component. At least two different responses of the cochlear implant to the test stimulation sequence are measured in parallel. The different responses include an objective electrophysiological response, and a subjective psychophysical response. A correlation between the different responses is evaluated to determine an appropriate fitting process for the cochlear implant patient.
