Age 70. I have a different hearing related problem as well as tinnitus. Background noise on my rig above about 2.4kHz seems awfully hissy to me. Above that point I have to start using the filters in my head to try and shut the hissing out. The mental filtering takes some effort and can lead to fatigue.
I'm not sure how this came to be for me, but perhaps it is what became to seem natural for me after listening to HF SSB through a pair of cascaded 2.4kHz filters (Icom IC-751A) for 16 years. And even with that, I'd tend to crank the passband tuning towards the lower end. In my setup, I run my K3 through an LP-Pan, NaP3 software and onboard 192kHz sound card. In NaP3/K3 I rarely run the filters above 2.4kHz top / 0kHz at the bottom. As well, I use NaP3's equalizer dropping several dB above 4kHz. The rest of the audio system is a 5.1 surround sound receiver with decent bookshelf speakers + subwoofer. I can tolerate wide band audio above 2.4kHz as long as it is well above the noise level, but generally don't find the audio above that range as particularly useful. Costco - A good ham friend of mine, somewhat older than myself used to swear by the Costco hearing aids. He was a PhD EE and had a pretty good appreciation for audio. I'm not sure if Costco offers different brands, but if there is a make that most agree on, can someone mention that here?
