Mapping is the term for programming a cochlear implant to the specifications and needs of its user.
MAPs are programs that help to optimize the cochlear implant user’s access to sound by adjusting the input to the electrodes on the array that is implanted into the cochlea.
The cochlear implant processor is connected to the audiologist’s computer for MAPping. Using a series of “beeps,” and measuring the CI user’s response, the audiologist sets T- and C- levels for each electrode. T-Levels, or Thresholds, are the softest sounds the CI users can detect. C-Levels, are Comfortable loudness levels that are tolerable for the CI user.
The audiologist might also adjust the stimulation rate or programming strategy used for the MAP.
