I like Neville’s comments and suggestion a lot. It reminds me of when I first started to wear my OPN1. I was so used to the noise reduction on my old Rexton that any noise that I couldn’t control and reduce from the OPN aggravated me so much. And as you know, the OPN basically opens up all the sounds to you. Sure, they do some balancing and this and that, but you still hear them all. After understanding why the OPN does what it does, because of this new open paradigm, I came to accept and embrace how it is. Within about a month, all the surrounding noises don’t bother me as much anymore. I learn that you can train your brain hearing to ignore what you don’t want to hear, and it’s a battle of will power. It’s not gone, it’s still there if you pay attention to it. But if you ignore it and don’t let it bother you, eventually it stops bothering you. Of course I don’t have tinnitus so it’s easier for me to say this (about ignoring the noises) than for you to put up with your tinnitus. But I think the principle is the same and I guess tinnitus is just another, but very bothersome, noise, after all.
In talking about the imbalance, I remember that in my very first fitting with the OPN, I noticed immediately as they turn on the HAs that the volume on my right side is much louder than my left side. It was interesting because they just programmed the original setting based on my audiogram, so why would I hear the imbalance right away? And by the way, my right hearing at the time has worsened by a bit compared to my left hearing, so I’m sure the original setting based on the audiogram took that into account and therefore boosted up the volume on my right side a little bit more to be create the balance in theory, based on the numbers, if anything. I could only conclude that my brain must have compensated for the worsened hearing on my right side and become more volume sensitive on the right side to make up for the gradually more loss. So that’s why I perceived the imbalance on the new HAs, even though on paper, the settings are probably correctly uneven based on the numbers.
The point of this is that it seems like you also have asymmetrical hearing since you mentioned that your left ear has been your better ear all along. So we don’t know exactly what happened except that your hearing is asymmetrical in the first place, and you perceived the imbalance after the second fitting and the owner confirmed an imbalance but the fitter denied causing an imbalance, etc. It’s just all too confusing to really know who’s right and who’s wrong and maybe it was just perceived differences after all for all we know.
In the end, I think Neville has the right suggestion here. Focus on training your brain hearing to ignore the tinnitus so that you can enjoy wearing your new OPNs again. I also read some posts on this forum where people say that their tinnitus got better after they wear HAs. Maybe it simply helps them focus on hearing the sound they want to hear so that they can ignore the sound they don’t want to hear.
