although i'm skeptical, i'm willing to leave a tiny amount of doubt in the

air. i think the evidence is clear that we cannot hear these frequencies.

there is some slightly woo-ish stuff about how they might still interact

with us physically and contribute something to the experience of being "in

the presence of" the live instrument(s). i suspect its totally bogus, but i

also don't think that the science has been done to clearly establish that

it is, and that 22kHz is a hard limit for human experience, not just human

hearing.
