Cochlear implant mapping, also known as programming or tuning, is the personalized adjustment of a cochlear implant's settings to optimize sound perception for the user. During mapping sessions, an audiologist measures hearing thresholds, determines comfortable listening levels, maps electrodes to specific frequencies, and fine-tunes settings based on the user's feedback. The goal is to enhance speech perception and understanding. Cochlear implant mapping is an ongoing process, involving multiple sessions to ensure the best hearing outcomes for the individual wearer.
