The importance and effect to and above 20kHz...

Hi Everyone -

I was wondering if anyone would care to elaborate on the importance of system frequency playback as the frequency range approaches and passes 20kHz. What effect does 15kHz have on music, for instance, and why is it important to keep the upper frequencies as linear as possible? How about 18kHz, or 20kHz, or 25kHz? What effect can these specific frequency regions have on the overall performance, and why should I keep them linear?

Let me clarify, I used those particular frequencies as examples, but if they can be expounded upon, then go ahead. I'm hoping everyone understands what I'm trying to get at. What effect can the upper treble frequencies have and why is linearity in these regions so important? Same goes for above 20kHz, say in the 22-30kHz region.

Can anyone explain?

Thanks for you help.

It's not important to me at all in my right ear, I can't hear the crickets in that ear anyway but if a system goes to 20khz and past it's a good indicator that the audible high frequency performance will be good. Systems that only claim 15 khz usually sound rolled off on the top end.

Thanx, Russ
