If you're ears aren't what they once were, your best friends are increased dynamic range, focus, detail and a more defined space between the notes."
Except you don't possess the same ability to hear dynamic range you once did, and turning it louder, only gives temporary relief but hastens the decline. You likewise will never get the high frequencies back, no matter what you do. Without the ability to hear as quiet of notes, and inability to compensate by cranking it even louder, you have now lost the ability to hear detail too, and putting more into the music, does not allow you to hear more if you are already at the limit. Refined space between the notes is interesting, that would be more an acoustics things, fast decay to reduce instantaneous complexity, because your brain is also a bit slower.
Don't worry, it is not all bad. Music is mostly under 10K, and almost all the acoustic cues for position are at even lower frequencies. Best thing about older, is usually less distracted and more time to relax and enjoy and to the point, actually listen, not just hear.
