Ears arse ears
Sorry did I say arse? Must be your hearing.
Well have had three’ish days with the Prisma 2 Pros and the open fit ear pieces.
To be honest I have given up for the moment, the problem that I have is that although they have a feedback cancelling circuit, because they are “open fit” – no ear piece as such – just a tube that sits in your ear, some of the sound escapes and gets picked up by the microphones hence the feedback. Now the feedback cancellation stuff works – BUT it isn’t instant and takes a fraction of a second to kick in. The other problem is that because I wear a wide brimmed hat when I am out (and its sunny) is that the sound seems to get reflected back into the microphones even more and things get worse. Also because the high end has been turned down a tad – high notes now get confused by the antifeedback stuff and they get really confused.
Now the highend stuff I will take responsibility for, and will ask to be turned back up and I will live with the sibilance crackling up a bit.
But I cannot deal with the continual feedback that fades in and out all the time, its driving me nuts. Its sods law that it started up around an hour after I left audiology as when I left I was quite happy. But then tuning the aids in artificialy quiet confiditions means that although they are set clinically correctly, they don’t necessarily reflect normal life.
Also don’t forget I was advised that I was borderline on my right ear as to whether the open fit stuff would actually be effective and that it was my choice to try them. At the end of the day for mild loss I expect that the open fit ear pieces would be fine, but my right ear is I can see the wrong side of the line, I have tried it and well its not working for me.
So out of desperation I phoned audiology this morning and explained that I was last weeks guinea pig and have some issues. They have managed to bring the appointment forward two and a half weeks for me, which is not bad – I can live with that.
So whats will happen in two weeks time? I don’t know. I guess that the options are:
1. stick with the 2Ms and have them retuned for the updated audiogram
2. stick with the 2Pros and have them retuned and calibrated for use with full ear pieces
Hopefully because of the occulsion affect that I am suffering from then we will have another go with new ear pieces maybe made of a slightly softer material – the current ones fit a treat but are not at all flexible, but then I didn’t get on too well with the softer material pieces last time as they were uncomfortable but at least didn’t lead to occlusion.
At the moment I pleased that I had prescence of mind last week (and a slightly niggly feeling) to hang on to the 2Ms – otherwise I would be absolutely stuffed at the moment and really hacked off.
At least if I do stay with the 2Ms then I know that they have the direct audio input stuff in stock – oh I do wish that they had told me about that stuff before I asked I really do.
