18 Claims

1. A method for adjusting operation of a stereo cochlear implant system comprising:

detecting first incoming sound waves at a first input source of a first cochlear implant subsystem of the stereo cochlear implant system;

outputting electrical stimulation from the first cochlear implant subsystem based on the detected first incoming sound waves and a gain of the first cochlear implant subsystem;

detecting second incoming sound waves at a second input source of a second cochlear implant subsystem of the stereo cochlear implant system;

outputting electrical stimulation from the second cochlear implant subsystem based on the detected second incoming sound waves and a gain of the second cochlear implant subsystem;

receiving a command from an external device to adjust a volume of the stereo cochlear implant system; and

in response to the received command:

adjusting the gain of the first cochlear implant subsystem by a first amount; and

adjusting the gain of the second cochlear implant subsystem by a second amount, the second amount being different from the first amount, so that a wearer perceives an approximately equal change in output of the first cochlear implant subsystem and the second cochlear implant subsystem;

after adjusting the gain of the first cochlear implant subsystem and the gain of the second cochlear implant subsystem:

detecting subsequent first incoming sound waves at the first input source;

outputting electrical stimulation from the first cochlear implant subsystem based on the detected subsequent first incoming sound waves and the adjusted gain of the first cochlear implant subsystem;

detecting subsequent second incoming sound waves at the second input source; and

outputting electrical stimulation from the second cochlear implant subsystem based on the detected subsequent second incoming sound waves and the adjusted gain of the second cochlear implant subsystem.
