What difference does that make? The upper limit of a person's hearing
has nothing to do with whether the high frequency signal is associated
with a lower frequency one. If anything, it'd be harder to detect the
presence or absence of a very high frequency component along with a
lower frequency fundamental because the latter would be much stronger.

Prove to me that you can HEAR 42 KHz and I'll believe you.
