Equal loudness contours are based on that, it's where speech intelligibility is and it certainly is the most developed and we have the lowest threshold for hearing in that frequency range.BONES wrote: Tue Sep 13, 2022 8:58 am No, there isn't. Perhaps there can be but it's by no means a given and it is just plain stupid to suggest otherwise. I'd also suggest that 2-5kHz is nowhere near our ears' most sensitive range, especially as we age. I can barely hear anything at 5kHz these days and there has never been a time when I've cared what's going on up there.
Generally, hearing doesn't decline in the high mids first - you get gradually more and more high frequency roll-off.
A lot of musicians have damaged hearing, because it's the most sensitive it's also prone to damage a lot. I suspect you might have hearing damage, from all the loud shit in your life.
However as you get much much older (70+), your hearing will also decline in the speech ranges.

Also it's not all that high. The fundamentals of upper piano octave are in 2-4k.
