Abstract: An exemplary system includes 1) a first sound processor included in a first auditory prosthesis system associated with a first ear of a patient, the first sound processor including a first volume control facility, and 2) a second sound processor included in a second auditory prosthesis system associated with a second ear of the patient, the second sound processor including a second volume control facility. The first volume control facility adjusts, in response to actuation of the first volume control facility, a first volume level perceived by the patient when electrical stimulation is applied by either the first auditory prosthesis system or the second auditory prosthesis system. The second volume control facility adjusts, in response to actuation of the second volume control facility, a second volume level perceived by the patient when acoustic stimulation is applied by either the first auditory prosthesis system or the second auditory prosthesis system.
