I think there are things about how we hear that we don’t know how to measure yet so I think there’s much more to our hearing than 20k-20hz. I have a friend who plays in an orchestra and has had a hearing problem his entire life ... never heard much above 10k ever but yet can tune an instrument better than anyone I know by ear. He certainly can tell the difference between reproduced music and the sound of the symphony at the symphony hall as most of us can. Live music unfolds in unique not predetermined ways depending on the venue and has other qualities that I think we all agree make live music a unique event that I’ve never heard recreated by even $1MM systems. If 20k-20hz was the defining factor in creating this event we would have solved this issue decades ago. Simply put it isn’t. There are many other factors that make live music special and we don’t really know how to measure that so why do we continue to use the fact that as we age and we hear less than 20k-20hz we somehow can’t appreciate the best in audio equipment? Asserting that we need to test our hearing for what is likely the least important factor in our perception of music makes no sense to me at all.
Agree? Disagree?
Interesting topic for sure
