Before spending a lot of money on high-end audio systems, it would be a good idea to do this test first:
 
Hmmmz... At a medium volume level I was capable up to ~13kHz. Hearing age 49.
 
Again, moderate volume. I got to 13500, hearing age 43. 19 years younger than my actual age. And this with mild right ear tinnitus.

I moved my head side to side slightly to avoid comb filtering effect at the higher frequencies.
 
I'm 55 years old and I've tested by sending these frequencies to my system by generating signals using the audacity software (not too strong so as not to take the risk of degrading the tweeters). I hear well at 14 Khz and almost nothing at 15 Khz).
 
Hmmm. 23 years older than I actually am.

Not surprising though.

Military. 30 years. Aircrew, choppers

30 years working 1-2 feet away from screaming jet engines, straight cut gear Helo transmission whine, whining hydraulics, unexpected max volume coms squeals in headsets and then when things went all "electronic", screaming cooling fans.

I'm actually a bit surprised it's not worse......

O' that's what that was. I was experiencing slight fade in-out at L & R at ~8kHz and then 11kHz.
 
btw there is no content in the above video past 16-17kHz (I assume due to YT compression)

For these tests one is better off with REW:

Yep - that'll do it.
 
Pretty much right on my real age... Let's just say the second half of that video was silent. :facepalm:

Is there any room tuning software or headphone tuning software that takes the listener's physical hearing limitations into account?

Sure. Use parametric EQ or EQ.
 
Got to 12500, big surprise, but will not tell the Misses. ;)
 
Between the end of 15,000 and the beginning of 16,000 I didn't hear anything anymore, but considering the post about yt compression cutting high frequencies it might simply not have reproduced anything anymore. In any case I hear over 15,000 at 41 years old and I'd say that's fine. My 43 year old partner didn't hear anything over 12,000
 
14.5kHz at medium level (I almost jumped to shut it down at around 5-7kHz,my annoying area)
I suppose I should be grateful considering age and use (55 yo) .

I'll test on headphones too,I'm curious.
