No, it means that if no mic in the world can record the mosquitos, they don=

The human reception is different then machines reception (not just the non-

Your nose is a lot worse in detecting smells then any mass-spectrometer is.
What makes the human different (some call it superior) is combining this=20

Of course there are legions of scientists and nerds working on making machi=
better in these parts too.
Going into psychoacoustics is not really contradicting the "machines can't=
measure it, still it exists". Machines can measure the frequencies the huma=

the effects aren't looked into as deep as the frequencies below 20kHz are. =

Which in turn makes most audio people discard frequencies >22kHz light-
heartedly. And they are right as the scientific (thus neutral) proof of the=
effect of the frequencies below 22kHz is _much_ greater then above. That=20
doesn't deny the psycho-acoustic effects, it only ignores them for the sake=
bandwidth, reliability and cost...
[*] Might also be that today's machines aren't good enough. Just compare th=
knowledge about the atom of today with that of 250 years ago...
