1. An apparatus constructed and arranged to determine operating parameter values for each of a plurality of stimulation channels of a cochlear implant, the apparatus comprising:

  • a measurement module configured to objectively measure values of the operating parameter for selected stimulation channels of the cochlear implant;

    an interpolation module configured to interpolate the measured values to derive an estimated value of the operating parameter for one or more non-selected stimulation channels of the cochlear implant; and

    a validation module configured to assess the accuracy of each estimated value by;

    determining an infra-test value and a supra-test value of the operating parameter that is less than and greater than the estimated value, respectively;

    applying stimulation to the cochlear implant based on the infra-test and supra-test values, respectively; and

    determining the estimated value to be accurate if the infra-test value does not whereas the supra-test value does elicit a neural response, respectively.
