Hi,
I am 34 and can still hear up to 16 kHz and even more (20 kHz it seems, if I pay good attention).
My speakers (Epos K3) have a range of 41Hz - 30kHz. Amplifier and DAC range are even larger.
Frenquency reponse of my system is quite flat after EQ (measured with a calibrated Behringer ECM8000 and REW, and corrected by convolution with an impulse created in RePhase and processed in JRiver), with a descending curve of 0.6 dB per octave from 40Hz to 20kHz.
Recently I've tried a Low Pass filter (Linkwitz-Riley 96dB/octave @ 22kHz). Up to 16kHz, it doesn't change anything. But it gives -2dB at 20 kHz and works plenty afterwards.
I listen to FLAC 44.1kHz/16bits, so there shouldn't be much in the 20kHz - 30kHz range.
But still, I find the sound smoother and less tiring with this filter.
It is theorically less "Hi-Fi" though.
Is it really possible that the huge attenuation after 22kHz make my ears/brain feel more confortable? Is it just because of the -2dB @ 20kHz? Is the trick elsewhere?
Thanks!
EDIT: As you will read below, I can't spot the supposed differences in "smoothness" in an ABX test.
I'm still interested in replies if someone has successfully taken an ABX in that frequency range.
