A system comprising: a stimulation management facility configured to direct, during a fitting session, an electro-acoustic stimulation ("EAS") system (100, 600, 700) to concurrently apply acoustic stimulation to a patient by way of a loudspeaker and electrical stimulation to the patient by way of an electrode (108, 708) to be located within a cochlea of the patient; and a fitting facility communicatively coupled to the stimulation management facility and configured to detect, during the fitting session, an interaction between the acoustic stimulation and the electrical stimulation, and set, during the fitting session, one or more control parameters governing an operation of the EAS system based on the detected interaction, characterized in that the fitting facility is configured to set the one or more control parameters by designating the electrode as being disabled subsequent to the fitting session, if the interaction between the acoustic stimulation and the electrical stimulation results in the acoustic stimulation being suppressed by the electrical stimulation, and in that the fitting facility is configured to set the one or more control parameters by designating the electrode as an enhancing electrode through which enhancing electrical stimulation is to be applied subsequent to the fitting session, if the interaction between the acoustic stimulation and the electrical stimulation results in the acoustic stimulation being enhanced by the electrical stimulation. a stimulation management facility configured to direct, during a fitting session, an electro-acoustic stimulation ("EAS") system (100, 600, 700) to concurrently apply acoustic stimulation to a patient by way of a loudspeaker and electrical stimulation to the patient by way of an electrode (108, 708) to be located within a cochlea of the patient; and a fitting facility communicatively coupled to the stimulation management facility and configured to detect, during the fitting session, an interaction between the acoustic stimulation and the electrical stimulation, and set, during the fitting session, one or more control parameters governing an operation of the EAS system based on the detected interaction, detect, during the fitting session, an interaction between the acoustic stimulation and the electrical stimulation, and set, during the fitting session, one or more control parameters governing an operation of the EAS system based on the detected interaction, characterized in that the fitting facility is configured to set the one or more control parameters by designating the electrode as being disabled subsequent to the fitting session, if the interaction between the acoustic stimulation and the electrical stimulation results in the acoustic stimulation being suppressed by the electrical stimulation, and in that the fitting facility is configured to set the one or more control parameters by designating the electrode as an enhancing electrode through which enhancing electrical stimulation is to be applied subsequent to the fitting session, if the interaction between the acoustic stimulation and the electrical stimulation results in the acoustic stimulation being enhanced by the electrical stimulation.
