I'd typically limit that to headphones, as other listeners would find 
the cranked-up treble to be too "tinny"/

Increased volume can help some to compensate - its the basic principle 
of a hearing aid.  Overall, the loss for men is that we can expect to 
experience a drop in upper range after age 45, which IIRC is often 
around 33% by age 55-60 (and more later).

A lot can also depend on how much we proactively protected our hearing 
from high dB hazards such as lawn mowers, leaf blowers, power tools, 
etc:  if you weren't already wearing hearing protection in your 20's 20+ 
years ago, its pretty likely that your upper range is already shot.

Finally, the loss is slow over time so its easy to overlook.  My last 
formal hearing test at my employer was pre-CoVid (~2018) which is how I 
know that I definitely have ("age normal") loss.  Since then, I've 
learned that I can't hear some higher pitched electronic beeps (oral 
thermometer), or some automotive "water pump bearing is going". 
Probably within five years or so now of needing hearing aids.
