No clear-cut answers but some options might include:
Noise generator hearing aid to treat tinnitus if it is hyperacusis rather than recruitment
Lower amplification in noisy restaurant type situations, combined with remote microphone. [If you have an iPhone the “Live Listen” feature is a simple but effective version of a remote microhpone]
High end hearing aids which can be programmed to address specific frequency ranges- such as Phonak Lumity or Paradise or Starkey Genesis
As a late-model Phonak wearer and DIY fitter this post piqued my interest! I will investigate compression of high frequencies. Meanwhile, I’m curious about which programs, er, programmes, you do use?
I do find that the new Phonak Lumity Life aids seem to help focus on speech even when I don’t have them in the dedicated “Speech in Loud Noise” program, but there are places where truly NOTHING works: like in the back seat of a car trying to hear what folks are saying up front. Even in that dedicated program, it lowers ALL volume down too much to grasp what’s being said. I’m hoping that if I keep the Roger V2 device on me, I could whip it out of my purse, point it at the speakers and go from there.
I’m on the road right now, so the Roger is in the hotel in it’s cradle. I’ve tried it out in restaurants, but not in that back-seat scenario yet.

P90s: I have the music programme as default, and comfort on echo as a 2nd setting. Autosense 4 is the 3rd setting. In all streaming settings (I’ve reduced the settings that are directional or reduce noise/wind/whistle)
M70s: Music as default, Speech in Noise 2nd, Autosense 3 3rd. Same with streaming as above.

I’m going to play around with the Speech in Car setting as I’ve just had my 3rd midlife crisis and bought a BMW Convertible. My wife tells me she doesn’t expect me to live until 126, so I may be getting too old for it 
Windblock will be the key here, but I expect it to be a double edged sword, in removing both wind, and speech frequencies. We shall see

I really empathize with your struggle to hear. I do a reasonable job hearing in absolute quiet. But any background noise really makes it hard for me to understand speech. And if that background noise IS human speech, I lose comprehension of the speech I’m trying to focus on. This happens even with Phonak hearing aids set to very tight beamforming. The assistive listening device I use, a Roger Pen, helps a lot. I use frequency shifting algorithms so some content from high frequencies becomes audible. Finally, earmolds with smaller vents than recommended by the audiogram prescription recommends help because the smaller vents block out more ambient sound. I hope this information is helpful.
The Live Listen feature on my iPhone has been a miracle for me. It’s the only way I can hear conversations or the TV.
Hey good luck to you in that 3rd MLC and the Speech in Car! Let us know if that works for you,
