I received conflicting information about running the feedback analyzer for the Genie 2 software on the OPN. Obviously this white paper says that you should run it every time something changes. I did have my audi run it on my OPN1 originally when I was fitted with 85dB receivers on bass dome with single vent fitting. And that was because I experienced feedback if I didn’t run it.
HOWEVER, if you go on audiologyonline.com and viewed one of the Oticon seminars on Genie2 programming, the presenter said that if there’s no feedback issue, they don’t encourage the feedback analyzer to be run and have feedback control turned on because it’ll take away some of the headroom gain which is one of the trade-offs of using the feedback analyzer.
When I mentioned this on this forum, one of the fitters who frequents the forum (maybe Um_bongo and Neville) said that this is old advice and the new advice from Oticon is to run it always.
Then when I recently changed my fitting with 105dB receivers using custom hard acrylic molds (still has a vent in it), I asked my audi about running the feedback analyzer again (because the new setup wiped away the old settings) and she asked if I experience any feedback. I said actually no I don’t (maybe the custom molds help in this regard, so she said that if I don’t have any feedback issue then she doesn’t want to run the feedback analyzer and enable feedback control, for the very same reason cited by the Oticon seminar I mentioned above, because it would require the tradeoff of losing some headroom if enabled.
I think that makes sense. If you have feedback issue then by all means run the feedback analyzer and enable feedback control. But if it’s not an issue then why run it?
