"Whatever hearing acuity curve you have is identical for listening to live music and for listening to recorded music at home."
That's about the silliest rationalization I've ever stumbled upon. How can a critic (or any other listener) meaningfully compare the performance of amplifier 'X' to amplifier 'Z', if they can't adequately hear the full frequency range output of the 2 amps, as is heard by a normal, healthy human ear?
With lenses, what's the bottom line that you can read on a standard eye chart. Inadequate performance and one's driver's licence is suspended (for your own safety as well as those with who you share the road). Ditto one's audio critic license.
Since loss of high frequencies with age (presbycusis) is normal, how old is a normal healthy human reader?
And while we are at it, spectral sensitivity is only one of several hearing attributes.
...the biggest change in hearing acuity is the loss of high frequencies as we age.
As JA has pointed out, he refrains from discussing the very high frequencies.
How much musical information occurs above 12kHz or even 10kHz? As you can see from the chart, probably 90% of the music is in the midrange (between 100Hz and 8kHz).
Regardless of extended HF hearing above the most important aspect of audio reviewing is the reviewer's critical listening skills.
Even with 20/20 vision, many can't see the forest for the trees.
Strange chart , no midbass ! Midrange at 240 hz ! Subbass at @60 hz ....
Uhhh Huh ...
Nice chart. Attribution?
Momentarily disregarding charts and statistics, I know from experience how the value of the resistor for the Tympani IV-A tweeter has changed over the last 25 years (in the same listening room/position). To derive *any* pleasure at all in listening to my 'test' standard CDs, I have NO resistor in place. ~30 years ago I started out by using Magnepan's supplied 2.5 ohm resistor. If I used that resistor today, my listening pleasure would be zilch. (Needless to add, I don't merely listen for the higher frequencies as heard by my dog.)
