The Hearing 2.jpg file is your audiogram. The Hearing 1.jpg file is your word recognition score and other basic measurements. You probably already know that your left hearing is worse than your right hearing. You really should be wearing hearing aids, at a minimum on your left year, but your right ear can definitely use the help, too.
There are ways to address your hearing issues that you’re complaining about. Open domes may seem like a logical fitting for your hearing loss, but if you have issues with and want to address the background noise problem more effectively, you may want to give up the open domes and use closed domes that come with one or two smaller vents. This is a compromise to give you some venting to minimize occlusion, but not so much as to let all the noise through and not be able to control it. It’ll also help make the sound not as tinny as it’ll contain more lows and mids from escaping through the vents. Your new audi can also give you a little more boost on the low end and mid area to balance out and make the sound not as tinny.
I suspect that your previous audi is a bit more passive (or lazy?) and didn’t want to deviate too much from the prescribed solution, even at the expense of you not liking the prescribed solution. Hopefully your new audi will be willing to work with you more to get it to your liking. And maybe you’ll also like the Signia sound better than the Phonak sound as well.
