title: Experiences of the use of FOX, an intelligent agent, for programming cochlear implant sound processors in new users.
abstract: OBJECTIVE
  This report describes the application of the software tool "Fitting to Outcomes eXpert" (FOX) in programming the cochlear implant (CI) processor in new users. FOX is an intelligent agent to assist in the programming of CI processors. The concept of FOX is to modify maps on the basis of specific outcome measures, achieved using heuristic logic and based on a set of deterministic "rules".
  
  
  METHODS
  A prospective study was conducted on eight consecutive CI-users with a follow-up of three months.
  
  
  METHODS
  Eight adult subjects with postlingual deafness were implanted with the Advanced Bionics HiRes90k device. The implants were programmed using FOX, running a set of rules known as Eargroup's EG0910 advice, which features a set of "automaps". The protocol employed for the initial 3 months is presented, with description of the map modifications generated by FOX and the corresponding psychoacoustic test results.
  
  
  RESULTS
  The 3 month median results show 25 dBHL as PTA, 77% (55 dBSPL) and 71% (70 dBSPL) phoneme score at speech audiometry and loudness scaling in or near to the normal zone at different frequencies.
  
  
  CONCLUSIONS
  It is concluded that this approach is feasible to start up CI fitting and yields good outcome.
