I have reverted back to my last mapping before we changed to 900hz. I apparently do not respond well to anything below 1000hz. However, I was getting this needle pinching whenever there was semi loud ssss or ssshh sound. It was painful that by the end of the day my right side of my head would just ache.

The lower channels caused the needle sensation and I already had channels 1-3 turned off, so I opted to turn off 4 as well. Feels much better now. I am running channels 5-16 which kind of balances out so I'm getting a full range of frequency but still I am missing some information. For example - say you have a piano with 22 keys (I forget how many keys they have), then you switch to a piano with 10 keys such as a keyboard. You still get full range from high to low tone, but not as much variation across the board. So my speech comprehension without context will be limited. Its like saying what is 4+_=_? You couldn't know what the answer was no matter how hard you tried, but when you add context, one is able to fill in the blanks.

Anyway, Cochlear has a new technology called bipolar channel or dual channel which increases frequency. I am current volunteering for that study in hopes to give them a chance to improve the mapping processes. The downside to that is it shrinks the battery life even more. I currently only get 2 days with 3 batteries.
