Another update....in the rarefied atmosphere of home, things were working well, but in the real world things needed to be different. My discrimination was not as good as I thought and relying on low end gain to compensate resulted in a lot of sound that obscured, rather than clarified, speech. Home programming to the rescue! Continued experimentation has boosted a few more frequencies to viable ranges and backing off on the low/mid regions has helped balance sounds better. Feedback continues to be almost nonexistent and my speech recognition is now recognizably better in most situations. I tried out a couple of noisy restaurants in the past week and found them to be OK. The HAs have four potential programs and the algorithm for noisy places is pretty good. I haven't tried the telecoil program yet, or some of the other options, but compared to my previous HAs, I haven't needed to. Next I am going to try a foam dome. I'm doing OK but want more...If foam domes help I may stop there but I have two other options above that in the form of mini molds (thin tube + canal mold) or a large tube BTE with conventional concha molds. So far, the comfort of open fit is so much better I hope I can find a workable tuning/dome combination that allows me to maintain it.
Finally, DeafDude: I have been following your blog but unable to comment upon it as I said I would. I will, but am not sure how to do that. Feel free to enlighten me!
