The science of the particular effect or effects resulting from the
addition of frequencies to > 20kHz to those below that range and
within the audible spectrum have yet to be set in stone (or a thesis).
That is the exact opposite of the advice to handle subsonic
frequencies with great care; you can fly supersonic as far as your
ears cannot handle. Basically, even when you're in an Anechoic
Chamber, you will not be able to benchmark the two cases, but the
signal which has the "enhanced" additions (think exciters in a loose
way) will work its voodoo on your ears and brain receptors, leading to
a more pleasing result of the two. Yes, average Joe will "feel" it
Those kinds of experiments are hard to conclude, as there are very
little numbers aside from the amount of experienced industry guinea
pigs and multiple sittings across weeks or even months.
As you may or may not know, Science is part voodoo too.
