Hi,
You hear often you lose hearing (especially) for higher frequencies as you get older. Nobody gets younger, so it makes you wonder if it will affect your mixing performance when you get there. Any thoughts?

I have found that if I bow my head down towards my mix console my ears seem to "open up" and I can hear the top, or more top anyway. Very disconcerting anyway.  

Yes. We've had several threads here about hearing loss and related. It does affect your mixing and everything. And the loss comes so slowly that you don't react to it unless you have your ears examined and are told you have a dip here and a dip there. Many have found ways to compensate it. I thought my hearing loss is due to excessive
noise during rock'n'roll youth, but to my surprise the doctor said the graphs looks like normal age related hearing loss. So I know that if something sounds too treble to me, it's already intolerable to people with normal hearing.
That's one of the reasons I use SPAN and reference tracks a lot.
 

I have a hearing test scheduled for Thursday.  I know I have tinnitus.  I am starting to have difficulty hearing single voices in crowded rooms, restaurants, etc.  Women's voices have become difficult to hear some times.  I am sure that it has effected my mixing, but I haven't noticed it so far.  Having other to bounce the mixes off of, helps a lot as well.    

What?

That's called ignoring.

To the OP. I use hyped earbuds to to check my hi-freqs. And I pass mixes by some of my friends here who do not seem to have a loss (yet).
 

They say that what you can't hear, you can't mix. Partially true I think..... you can always use reference and visual material. Spectrum analyzers are one tool that let you see what's going on in the mix.  
Getting feedback on this forum and from friends who know music and don't have high freq loss would be good options as well.

The way I see it, my inner EQ curve as off when I was younger. With age it's settled down to perfection- yeah right.

Truth!!
 
I've had permanent tinnitus in one ear for nearly a decade now. Discerning single voices out of many is nigh on impossible, everything just sounds like a wash of noise inside my head.
