My ears of tin are over 50

Only if the acoustics are right and the Dr. is the one you want to examine you....

My missus thinks I am deaf because every time she calls me
to do a chore or something I never fail to not hear her.

I got MORE sensitive to bad sound at 50. I could not tolerate piercing highs, uncontrolled bass (especially midbass) and shouty, punchy midranges. Thus I needed to upgrade a lot. I can hear the differences between interconnects and power cables loud and clear, more than ever (maybe from experience, but it sure seems like my ears hear it). I really need those Stealth Indras now, unfortunately. So there.

Rgs,

I am similar. Its almost as if losing ability to hear the higher frequencies one can when younger facilitates an improved focus on what you can still hear.

I consider myself fortunate that my ability to appreciate good sounding music has perhaps waxed and not waned with age, at least so far.

I'm also over 50 and had my ears checked last year. I was told I still have surprisingly good hearing for the most part BUT some higher fequencies were issues if the volume is lower 50db. Not a problem I listen at higher volumes than that.
Considering I work on large commercial HVAC equipment I think I am very lucky.
