I’m using 5 year old aids these days - BTE Phonak Certenas. About a year in I discovered I had to replace the small foam filters on top of the “sound input” area (microphone) on the aid. It did seem to make a difference in sound quality. It’s just a small piece of foam cut to fit on top of the mic area. I can’t imagine that all aids would have them, but it’s a great example of something I now try to keep around for regular maintenance.
I have ear molds, as opposed to domes, so I have to keep my tubes changed on those - actually I found your thread in searching for an answer to another question - does tube diameter matter? Seems I am #13 thick tubes right now, the 13 I think refers to the diameter and the thick is the size of the wall. I read somewhere that low frequency losses like mine require a thicker walled tube. But now I’ve replaced my tubes and the “stuffy head” feeling I sometimes get seems a lot worse. So maybe I’m going to get rid of the thick walled tubes and try something around mediums. Not sure. The closest audi to me is 1.5 hours of curvy roads, so I’m much more interested in knowing how to do this stuff myself.
bherring1964, I wonder if you might have any thoughts on the tubing diameter question. I’m also definitely hoping to be building a little HA toolkit of my own - any recommendations of specific tools? I think the threaded part of my aid that attaches the ear hook is getting worn down, I’d love to replace it but I think I will wait until I have new aids (hopefully within a few months) until I see if I can find a screwdriver small enough to open the aid.
