1. A system comprising:
a memory storing instructions;
a processor communicatively coupled to the memory and configured to execute the instructions to:
direct a display screen to display a graphical user interface that includes a selectable option to perform an electrode sweep with respect to a plurality of electrodes disposed on an electrode lead implanted at least partially within a cochlea of a recipient of a cochlear implant, the electrode sweep including all of the plurality of electrodes recording evoked response measurements in response to acoustic stimulation having a frequency being applied to the recipient;
detect a selection by a user of the option;
direct, in response to the selection of the option, an acoustic stimulation generator to apply, by way of a sound delivery apparatus, the acoustic stimulation having the frequency to the recipient;
direct the cochlear implant to use each electrode included in the plurality of electrodes to record an evoked response measurement in response to the acoustic stimulation;
determine an amplitude of each of the evoked response measurements recorded by the plurality of electrodes; and
present, within the graphical user interface, a tuning curve that graphically indicates the amplitudes of the evoked response measurements.
