2nd Bilateral Mapping - Balancing the Two

April 18, 2008
posted by  Carole M - Cochlear Volunteer


By the time I went for my second mapping I knew I needed to bump up the volume. I could not really tell if the second one was on or not unless I took the magnet away for a minute. I wanted more sound from it. I discussed everything with my Audi and told her I rather liked how music sounded even though it sounded far away.

            First, of course, we did the “beep dance”. It was a little stressful and I felt I needed to really pay attention to hear the number of beeps. I pretty much got most of them and afterwards realized how tense I was. Okay, now we are going to do some beeps with the older CI. Piece of cake – I could hear them loud and clear. They just sounded different so I asked if they were the same frequency as the ones I was listening to with the new CI. To my amazement they were. Of course! I was really struck with how much my first implant has improved. The new one is just a baby…awww.

            My Audi then told me that they were going to turn each one on to see how it sounded, then both together and try for a comfortable, balanced sound. After just a little tweaking of both for quality and comfort level of hearing she then told me she was going to turn them both on. I realized that I will really be hearing out of BOTH ears at the same time after 40 years of not being able to. Emotional moment? Oh yeah!

            With almost no adjustment the sound out of both of them was balanced and sounded great. It was interesting how she had me look at her nose and then listen to what she was saying. Already I could tell that the quality of sound was much richer than with just one. Since I was getting sound out of both neither one was putting out a lot of volume but both together had all the volume I needed. Now the older one does not have to work so hard to listen…how cool.

I was still experiencing each ear doing their thing. In a way it made me think of those lizards whose eyes rove around in different directions. I mean you are listening to the same thing with both ears but at the same time you are still aware of each one. It didn’t take even a day this time for my brain to put it all together.

I now have both programmed with the same thing. The first two are for everyday listening and music with smart sound 2 Adro. The second one is the same as the first only louder for when I am ready for more volume. The third program on both is for listening in noise and the fourth is “focused listening”. It is a combo of Adro, auto-sensitivity and beam…real fancy! Can’t wait to try that one.

I'm so excited and appreciative that you are being so detailed. I have been scheduled for my bi-ci on June 23 and it helps me so much to have some idea of what having two is going to be like. Please keep adding new details, and I wish you a wonderful journey to bilateral hearing! Marcy

Hi Carole, I'm a little confused. You call this your 2nd map but report as if you were hearing with both implants together for the first time? Were you only wearing the new one alone for a while, or was it not yet effective enough to balance with the other when mapping? Just curious. Is your everyday program ADRO + Whisper? (I believe this is what Cochlear has labeled the "music" program). I volunteer once a week in my younger (teacher) daughter's kindergarten class, and find ADRO/Whisper works GREAT with hearing softer spoken small children. I also like this program to hear TV from a distance. You mentioned that with "both together (you) have all the volume (you) needed". This is called 'bilateral summation'. People experiencing this usually find that they turn their processor settings down a little bit on each side from the levels the processors were individually mapped at. If for some reason they are only wearing one processor, they usually need to turn it back UP to the originally mapped setting because it's too soft sounding when using by itself. A nice spinoff of bilateral summation is that the lower processor settings will save you a teeny bit of battery life! ; ) Camille

Hi Macy and Camille - First, I am really happy to hear that you got your approval Macy! Camille - sorry for the confusion. I did have both turned on from the first activation and was listening with both. At the activation I just had the new CI mapped - not the older one. My new one was turned on but was very soft. It was my Audi's idea to just get the nerve use to being simulated while still relying on my older one to do the listening. So I really could not tell if it was on until I moved the magnet away from the receiver. This second mapping was done for both and as you mentioned it was the bilateral summation. Wow - I did not know that. All I knew was that now the sum is greater than the parts. I plan to get a copy of my new mappings soon and will see if she combined Adro with whisper.

So now you've got the "real deal" with both implants programmed at the same sound level! Have you noticed anything specific about how you're hearing differently now? Localization better? Hearing TV without captions more clearly? Hearing without looking at a person more accurately, or hearing something you didn't expect to from further away or in an undertone? ANYTHING different??? ; ) Camille
