Yesterday was my MAPping appointment, nothing exciting….just your usual MAPping appointment. The volume was increased and I was given additional programs (eg. Noise, Zoom, and Music). My MAP hasn’t changed that much.
My audiologist is very pleased with how quickly things are moving and she wants me to go one more week before going bilateral. However, she did say to wear the left CI at times so it doesn’t become lazy.
She did the NRT (Nerve Response Telemetry) to make sure the electrodes were stimulating the nerve and that it looked okay compared with my MAP. It looked great.
As for MAPping all it consists of is going through each electrodes and you let the audiologist know when you first hear something and when it’s at a comfortable loud level. It’s more tricky than it sounds since each electrode sounds different and you’re not sure what you’re listening for. You’re not sure if you’re hearing it or not at first because it’s so quiet. Only about 10 of my electrodes are mapped individually even though I have 22. If I remember correctly from my first implant, they do this since each electrode are really near each other and they can use the computer program to map the remaining…or something like that.
It also involves listening to two different sounds and then having to inform the audiologist if those two sounds are at the same volume or if one sounds louder than the other. This is also more tricky than it sounds since the two sounds are at different pitches. It took me forever with the first implant to figure out how to listen to the volume even though sometimes the differing pitches made it difficult. This helps ensure the sounds are balanced. I would say this is done about 20 times (10 times at a quieter volume and 10 times at a louder volume).
What we expect to do at next week’s appointment:
–Switch the speech coding strategy from a slower one to a quicker one (sounds will be processed quicker)
–Map the Nucleus 5 for my left ear so I can go bilateral
