The implants have been placed successfully within Harry’s head (and ears) so the next stage is for the Cochlear Implant Clinic ‘s audiologists to start programming the processor that feeds the information to the auditory nerve and then the brain . These are referred to as “mapping sessions” and Harry will have 12 weeks of mapping and observations as part of his intervention. Mapping is the name given to the process of measuring the amount of electrical current delivered to the cochlear by the implant. It is the process that ensures the patient receives comfortable sound levels. So our countdown to “switch on” (or ‘HHH’ as Dan and the girls call it, ‘Harry Hearing Hour’) next Thursday is the day that the audiologists will start to set his sound threshold levels and comfort levels. They will also hand over to us two James Bond gadget style huge suitcases full of the external part to the cochlear implant.
Check out the diagram on Cochlear’s website that shows you all the parts. There is a good video here too
