A coding strategy is a series of calculations used by the cochlear implant system to measure the sound that is presented to the microphone, analyze its components, and then determine which electrodes should be stimulated and how they should be stimulated to best represent the original sound. Next, it generates a code that is set to the implanted portion of the system. This code tells the implant which channel address to stimulate within the cochlear implant, when to stimulate it, and how loud that stimulation should be to accurately represent the sound at the microphone. This happens many thousands of times per second. Two coding strategies for example are CIS and SAS.
