'deaf' above 14kHz, appear to hear above that frequency -- hypothesis as to how.

Because hearing also involves processing in the brain. It's not just your ears. That's why I can still (with typical age compromised ears) still tell mp3 from CD. Many younger people can't. It's not their ears, it's their brain, which hasn't been taught the difference, so they don't notice it.

 

I would love to have been there for the blind testing. 🙂

For the interested ones I point out the differences. Like other things in listening, once you are aware of them, you can suddely hear them. The downside is that I've ruined mp3 listening for them.😃

 

I assume you are talking about 320 Kbps MP3s (and especially not 48 or 96 Kbps as found on some internet radio streams)?

 

As an aside, I always wondered why most audio engineers and mixers are mature/old people. Why is this if they can’t hear as good?  Maybe they can hear "good enough"?

Because unless your hearing deficiencies are severe, experience and listening ability counts for a lot.

In addition, frequency sensitivity depends on sound levels. At lower levels, our ear sensitivity in the bass and treble areas, drops significantly.

 

So that explains why I always listen to my music loud -- I let my brain do the EQ.
